Análisis de desempeño del uso de grano de caucho reciclado en mezclas asfálticas para mejorar la resistencia a la fatiga
(Universidad de Cuenca, 2024-10-04) Cabrera Reyes, Felipe Esteban; Galarza Prado, Bryan Ismael; Mogrovejo Carrasco, Daniel Estuardo
The present study focuses on the design of asphalt mixtures with the incorporation of wet recycled rubber grains, with the objective of comparing their physical and mechanical properties, with emphasis on fatigue resistance, compared to a conventional flexible pavement, and to determine their sustainability in order to consider them as an environmentally viable alternative for the recycling of end-of-life tires. To ensure the reliability of the results, characterization tests were carried out on the aggregates, recycled rubber grain and asphalt bitumen, following the specifications of the INEN, NEVI-12 and ASTM standards. The Marshall method was used to prepare 48 test specimens with rubber percentages of 0%, 10%, 15% and 20%, and with an asphalt percentage of 6.7%. Of these, 12 were subjected to Marshall tests, 12 to loading and unloading tests, and 24 to indirect tensile tests. It was determined that, for fatigue resistance, the asphalt mix with 15% recycled rubber had the best performance. Therefore, this optimum percentage was used to perform the life cycle analysis of this asphalt mix compared to a conventional one. It was concluded that the asphalt mix with 15% recycled rubber showed a considerable reduction in environmental impacts according to the TRACI2.1 methodology.

Fiberglass concrete began in Russia in 1940, giving rise to fiber cement. Concrete has good compressive strength; however, its main problem is that it lacks tensile strength, the addition of fiberglass increases the tensile strength, mitigating this problem, in addition to providing other advantages such as: lightening, control of cracking, and there was a residual resistance causing ductile type failures. It should be noted that the use of fiberglass is not common in Ecuador, although it is cheaper than steel fiber (the most used fiber). In order to increase the tensile strength in concrete, we design a standard concrete and 3 alternative ones with different percentages of fiberglass, in order to find the optimal endowment that presents us with the best results of: traction, compression, workability and economy. Thus, demonstrating the feasibility and sustainability of this concrete. Based on research carried out by other authors, we chose a fiber length of 5cm in order to obtain the greatest adherence between the cementitious matrix and the fiber interface, and a starting percentage of 0.5% of the total mass of the concrete, the results demonstrated an excessive decrease in workability, making the concrete of rigid consistency, for this reason we decreased the fiber percentages to: 0.25% and 0.35%, obtaining concretes of plastic consistency, and in turn significant increases in tensile strength, and weight decreases, however the compressive strength is slightly affected, that is why a water-reducing additive (Viscocrete 4100) was used, in order to obtain compressive strengths greater than that of structural concrete ( 20Mpa) The results demonstrated that the fiberglass causes a significant increase (34%) in the tensile strength, directly proportional to the percentage of addition of the fiber. In addition, fiberglass causes an incorporation of air, causing an increase in its absorption and a decrease in its weight.
Análisis de la seguridad y accidentalidad de la Av. de las Américas, en función de las propiedades superficiales
(2019-10-29) Barriga Zhindón, María José; Chaca Guamán, Jéssica Alexandra; Mogrovejo Carrasco, Daniel Estuardo
The main pavement function is bonded to the circulation and displacement of the vehicles, which by providing adequate properties will increase the users’ acceptability and safety. The Americas Avenue is considered one of the main arteries for the traffic flow in Cuenca city, where is necessary to determine whether the surface properties of the pavement influence the accidentally of the road. That is the reason why this investigation is focused on the evaluation of the surface properties in the critical points of the Americas Avenue, considered one of the principal traffic flow arteries in Cuenca. Five lengths were chosen for the determination of macrotexture, rugosity and PCI (Pavement Condition Index), analyzing the existence or not of correlations between these properties and the accident rate, considering a treatment matrix based on the results. In terms of macrotexture, the sections that failed to comply with international standards in Spain, Mexico, Argentina, Peru, and Brazil, are Jacaranda Park, Miraflores Park and Carlos Vega Arìzaga - Francisco Aguilar (Fair Free), with MTD values <0.5 mm. For national regulations, all sections comply with the specifications except the section of the Jacaranda Park and half of the Carlos Vega Arizaga-Francisco Aguilar (Fair Free) section with MTD <0.3 mm. In the case of roughness, data were obtained that did not comply with national or international regulations as they have values greater than 5 m / km. Regarding the PCI, there were variable ratings between “Very Good”, “Good”, “Regular” and “Bad”. Which threw a "regular correlation" unlike that with the other properties there was an "absence of correlation." Depending on the correlation obtained between accident and PCI, they were suggested for the sections that have a “Regular” PCI, a bump, fissure sealing or replacement of damaged potholes. On the other hand, in the areas with a “Bad” PCI the application of a micropavement is proposed.
Análisis de la tensión de adherencia del hormigón con el acero de refuerzo en diferentes estados de oxidación y diferentes tratamientos de pasivación y protección
(Universidad de Cuenca, 2021-11-09) Barros Ochoa, Carlos Julio; Mogrovejo Carrasco, Daniel Estuardo
Reinforced concrete is one of the busiest construction materials in the world, its operation is based on the adhesion between concrete-steel, in this way it allows the steel to take the tensile forces, maintain the union between the two materials, taking into account the adhesion capacity it carries and the susceptibility of factors such as corrosion processes, the types of rebar of the steel rods and the passivation products, which can positively or negatively affect the adhesion capacity between these two materials. The study was developed using an experimental model based on the “pull out” test, which allows to measure the variations in tensile stress due to potential changes induced in the adherence between these two materials. In this way, the “pull out” tests were proposed with different configurations to carry out the study and thus obtain knowledge about the behavior of adherence in the construction field. Specimens were made with different oxidation configurations of the rod, the type of rebar of the steel and the passivating agent. By means of the hydraulic press of the soil laboratory, "pull out" tests were carried out and the load-displacement results were obtained, with which the adhesion stress was calculated and thus, the influence of the different factors could be statistically analyzed that were raised in the study.
Análisis de las propiedades y beneficios del uso de madera plástica como material sostenible en el área de la construcción
(Universidad de Cuenca, 2024-09-13) Peñafiel Vicuña, María Paz; Serrano Tapia, Ana Carolina; Mogrovejo Carrasco, Daniel Estuardo
In search of sustainable improvement in the construction field, this investigation explores innovative alternatives that promote more environmentally friendly and economically viable practices. The study focuses on the evaluation of plastic wood as a potentially sustainable construction material, compared to traditional natural wood. Standardized and experimental tests, including shear, bending, compression, fire resistance, and wear tests, were conducted to evaluate the mechanical behavior and durability of both materials. The experimental methodology incorporated the exposure of samples to simulate environmental stressors, such as immersion in fresh and saltwater, burial, and outdoor exposure. This approach allowed for an assessment of the materials' responses to different environmental scenarios, providing valuable data on their performance in real-use conditions. This study focuses on the analysis of the environmental impact and sustainability of both materials. To achieve this objective, the Leopold Matrix method was used. Plastic wood, manufactured from plastic waste, represents a prime example of a circular economy, significantly contributing to waste reduction and resource reuse. In contrast, the sustainability of natural wood is critically examined, considering the negative effects of deforestation and unsustainable logging practices. The research aims to provide information to motivate the adoption of more sustainable materials and techniques, showing practical applications where the use of each type of wood is intended to be simulated.
Análisis de optimización de la relación costo/resistencia para hormigones estructurales con el uso de aditivos, y cálculo de su sostenibilidad mediante herramientas de análisis de ciclo de vida
(Universidad de Cuenca, 2022-08-29) Gárate Ortiz, Juan Diego; Mogrovejo Carrasco, Daniel Estuardo
The following study seeks to determine the optimal values for the implementation of water-reducing additives for structural concrete mixtures. A 250 kg/cm2 control mix was designed using the ACI 318 standard from 2008, along with proposed concrete mixtures using: medium range, high range additives and superplasticizers, these being: Plastocrete 161HE, Sikament HE200 and Viscocrete 4100 respectively, dosed with the average and maximum percentage according to technical specifications of each additive. The process consisted of making 20 x 10 cm cylindrical concrete specimens in batches of 12 specimens for each concrete with a different percentage of additive, and an extra 12 control mix concrete specimens (concrete without additive). The specimens were used to determine their resistance with indirect compression and traction tests at 8, 16, 28 days after their casting. The compression test was intended to verify that the resistance is not significantly altered by maintaining the water-cement ratio of all mixtures while saving on the amount of cement, and the indirect tensile test was intended to analyze the physicalmechanical properties with the use of additives. Sustainability and cost analysis were also carried out, finally a weighted multi-criteria process to determine the most optimal concrete was implemented in order to decide the best structural concrete mix with a comprehensive and robust analysis tool.
Análisis de patologías en la plataforma de rieles del proyecto tranvía cuatro ríos de Cuenca
(2017) Vásquez Berrezueta, César Adrián; Vásquez Berrezueta, César Augusto; Mogrovejo Carrasco, Daniel Estuardo
The significant number of pathologies found at the "Tranvia de Cuenca" project, located in Mexico Avenue; represent a big concern for future performance of this infrastructure. Infrastructure evaluation was performed by the use of non-destructive testing, this information was used for structural modeling to understand the behavior of the analyzed infrastructure under the predicted loads. The results show that it was possible to determine the origin of the pathologies, and therefore the possibility of drawing the correct alternatives to solve the problems. The performed forensic tests and modeling were among others: cracking analysis, ultrasound monitoring, rebound hammer testing, carbonation depth tests, and infrastructure modeling using ANSYS software. The conclusions show that most of the cracks were originated by the lack of reinforced steel into the platform layers, along with concrete contraction and retraction due to temperature differentials and bad or no curing. Furthermore, the concrete analyzed on the platform presents properties and physical changes because of constructive flows like: insufficient vibration, inadequate curing, or added water (with no control) during construction to facilitate workability; potentials of active corrosion is also a problem, due to carbonation penetration at critical location (around 70% of the coating). . Recommendations focuses on sealing active cracks with non-rigid sealant i.e. polyurethane) and the passive cracks with epoxy resin injection, or micro cement. Finally, it is recommended as well to recover the structure’s monolithism on the slabs, in order to have a better stress distribution.
Análisis de propiedades del hormigón a través del ensayo no destructivo de ultrasonido
(Universidad de Cuenca, 2022-07-07) Yunga Guamán, Flavio Josué; Zumba Cabrera, Anthony Leonardo; Mogrovejo Carrasco, Daniel Estuardo
Non-destructive methods are a methodology used to determine the properties of concrete, these tests are of interest since they preserve the structural integrity, in addition to this, they are economical and with the adequate analysis the results are reliable; Among these tests is the ultrasound test, there are numerous investigations that have determined the factors that influence these measurements, which has limited their use. It is currently used to determine the depth of cracks and in certain cases it is applied to quantitatively analyze the condition of concrete. Various studies have been able to identify that a general relationship cannot be established, since the properties of the aggregates depend on the sector from which they come. Due to these backgrounds, the present work aims to determine if it is feasible to use the ultrasound test to determine the compressive strength, because the aggregates used in the area come from the same sector, the results obtained are applicable only in the locality. Therefore, we have worked with more than 500 samples from two local concrete mixers with which a statistical analysis was carried out, in order to determine the existing correlation. After this, the trial was taken to the field, where the results of ultrasound and rebound test were compared. Additionally, the influence of the presence of reinforcement and cracks on the measurements is established.
Análisis de sensibilidad de variables para evaluar el desempeño de pavimentos rígidos para aeropuertos, diseñados por el método de la FAA.
(2019-04-22) Bravo Palacios, Giovanna Janneth; Mogrovejo Carrasco, Daniel Estuardo
The following investigation consists in analyzing the sensitibilty of variables in the design of rigid pavements for airports, by varying and combining input parameters related to the quality of materials and traffic characterization. In the case of materials, these were defined according to the provisions of the FAA and the MOP, in order to establish an analysis that meets the needs of the environment, on the other hand the parameters related to air traffic are constituted by the characterization of two airports that supply the current requests for transport in the country. From the sensitivity analysis we will obtain the variables that mainly influence the design of rigid pavements, from which to establish a model that allows to design pavement structures in a practical and reliable way.To evaluate the performance of the designs obtained, analyzes will be applied in an integral manner, for which three study areas were established: structural, economic and environmental. In the case of structural analysis, the stresses and deformations to which the structure is subjected to different depths of the layers were determined; while in the economic analysis a life cycle cost analysis (LCCA) was applied, to determine the costs of the designs determined from the beginning until the end of its useful life, finally for the environmental analysis it applied a life cycle analysis (LCA), where the greenhouse gas emissions of the designs were established. From this integral evaluation, the functionality, safety and sustainability of the proposed designs can be defined with the mathematical model.
Análisis de trabajabilidad/ resistencia/ y costos de mezclas para hormigones de elementos prefabricados con el uso de aditivos
(Universidad de Cuenca, 2024-01-16) Medina Mejía, Magaly Katherine; Mogrovejo Carrasco, Daniel Estuardo
The present project focused on the analysis and design of concrete used for prefabricated elements with the implementation of water-reducing additives. The case study arose from the need to define an optimal dosage since the company currently does not have one, as their mix designs are empirical. The aggregates used in the mix designs were properly characterized and met the requirements set forth in ASTM C33. A concrete mix was designed with a stress of 300 kg/cm2 according to ACI 211.1. The water-to-cement ratio was kept constant in each design, and additives with different ranges of water reduction were implemented, ranging from medium, high, to superplasticizer. The additives selected were Plastocrete 161 HE, Sikament HE200, and ViscoCrete 4100, respectively, all from the brand Sika. Once the results of each proposed design were obtained, the properties in the fresh and hardened states were analyzed, as well as the cost per m3 of each mix. It was concluded that from an economic and strength perspective, the best alternative was the design that contained the ViscoCrete 4100 additive in its composition, as the price of the concrete per m3 was only $49.59 and its early-age strength was superior, reaching 225 kg/cm2 , which represents 75% of the required strength. After 28 days, it exceeded the required strength, reaching 402 kg/cm2
Beneficios físico-mecánicos y análisis de sostenibilidad de hormigones porosos elaborados con materiales locales
(Universidad de Cuenca, 2023-09-27) Sánchez Arízaga, David Federico; Mogrovejo Carrasco, Daniel Estuardo
Internationally, the use and study of porous concretes have been widely developed due to the sustainable benefits they have shown to bring. However, there are very few local studies dedicated to this subject. This paper investigates the contrasts of producing permeable concrete using two types of aggregates from the province of Azuay: rounded river aggregate, crushed aggregate, and a combination of both. The study characterizes the aggregates and highlights the benefits of each mixture by analyzing slump, indirect tensile strength, percentage of interconnected voids, permeability, and CO2 emissions. In addition, standard mixtures of conventional concrete were prepared using each type of aggregate to compare the advantages and disadvantages of the permeable samples. In order to thoroughly analyze the impact of the aggregate in each mixture, we maintained the same water-cement ratio and percentage of admixture. For the permeable mixes, only the percentage of cement paste (cement, water, and admixture) was varied, while the inclusion of fine aggregate was excluded. After the study, it was determined that the concrete with the best performance was the one made with coarse crushed aggregate. However, it was also found that incorporating a portion of coarse rounded river aggregate can enhance strength without significantly reducing permeability or slump, or impacting emissions.
Correlación entre el índice de rugosidad internacional (IRI) y deflexiones medidas mediante deflectometría de impacto (FWD) para la optimización del análisis de desempeño del pavimento
(Universidad de Cuenca, 2022-03-10) Armijos Garate, Mateo Patricio; Fernández Landívar, Ivan Schneider; Mogrovejo Carrasco, Daniel Estuardo
The road parameters of functionality and structural capacity are indicators to evaluate the pavements based on the service level and capacity. (AASHTO, 1993) In Ecuador, the lack of control and maintenance is due to the low availability of evaluation equipment such as the Falling Weight Deflectometer (FWD). In the present research, a relation between the International Roughness Index (IRI) and the deflection measured with (FWD) on the Cuenca – Molleturo road is search, in the section between the abscissa 10+000 and 30+000. For the IRI measurement, the mobile applications RoadRoid and IRI.Calc.Free are used, which must be calibrated in order to validate the measurements. Through the use of digital tools, georeference, tabulation and data filtration are used to analyze the parameters that affect this type of measurements. In addition, deflection measurements with Falling Weight Deflectometer are provided by the MTOP. A sensitivity analysis of variables is used to find the maximum coefficient correlation possible. The results reached using a sensibility analysis show that exist a better relationship between IRI and the deflection, if consider: the central deflections, an interval of 100m the implementation of the moving average of 10th order, a determination coefficient of 0.26. In addition, when estimating the IRI for the same date when deflections were measured, a determination coefficient of 0.406 is reached, concluding that the relationship decreases with the time.

(2019-10-30) Gómez Rodríguez, Diego Patricio; Hurtado Piña, Juan José; Mogrovejo Carrasco, Daniel Estuardo
In this work a road infrastructure management system of the Miraflores - Sinincay - Racar section is carried out, in the Cuenca canton, province of Azuay in Ecuador. The management methodology consists in developing an inventory of the elements that make up the road network and carrying out a survey of the deteriorations along the 9.2 kilometers that comprise this section of road, to generate a database that allows an evaluation of the surface condition of the pavement using the methods of the PCI and Windshield Survey. The results of the evaluation were categorized into four groups Good, Regular, Poor and Failed and from this it is proposed to carry out the alternatives of Patching, Bituminous double surface treatment, Overlay and Reconstruction respectively. Markov chains are used to predict future pavement conditions, based on the determination of the current condition and considering the condition that would be reached when implementing maintenance alternatives to correlate it with the deterioration of the pavement. The above will allow intervening in a timely manner with the appropriate maintenance alternative to improve the level of functionality of the road.

(Universidad de Cuenca, 2024-09-23) Rea Caldas, Juan Diego; Mogrovejo Carrasco, Daniel Estuardo
This thesis addresses the development of a road infrastructure management system for the segment encompassing the Guangarcucho Bridge, the Guarumales-Méndez roundabout, and April 16th Avenue, focusing on planning solutions aimed at cost optimization and sustainability. The research concentrated on creating a detailed inventory of the existing road infrastructure, assessing its condition using methods such as the Pavement Condition Index (PCI) and the Windshield Survey, and applying Markov matrices to predict the evolution of pavement condition. The methodology included collecting field data, which revealed that 56.42% of the segments are in average condition, 32.12% in poor condition, and 11.47% in bad condition, and modeling maintenance and rehabilitation scenarios to determine the most cost-effective strategies. Additionally, a sustainability analysis was conducted using tools like PaLATE, which showed water consumption of 8,958 kg for alternative 1 and 6,138 kg for alternative 2. The INVEST tool was also used to evaluate the environmental impacts of the different maintenance alternatives, achieving scores of 76 and 51, respectively. The results of this research demonstrate the effectiveness of an integrated pavement management system that incorporates cost and sustainability considerations.

(Universidad de Cuenca, 2025-03-31) Crespo Quintanilla, Juan Andrés; Orellana Salinas, Cristopher Teodoro; Mogrovejo Carrasco, Daniel Estuardo
This thesis project develops a road infrastructure management system for the Paccha-Nulti- Challuabamba route, located in Cuenca canton, Azuay province, Ecuador. The management process involves creating a detailed inventory of the 9-kilometer road, identifying the structural elements of each segment and documenting the various failures present. Based on this database, the pavement condition is evaluated using the Pavement Condition Index (PCI) method and the Windshield Survey technique, categorizing the segments according to their current condition. Furthermore, Markov transition matrices are employed to predict the evolution of the pavement condition over the next 25 years, considering the current state of each segment and incorporating various intervention alternatives for the road. Finally, an analysis of the proposed intervention options is performed, focusing on the benefit-cost ratio of each alternative to enhance the road’s functionality, safety, and user comfort, while extending its service life and optimizing economic resources.
Desempeño, factibilidad y sostenibilidad de hormigones hidráulicos estándares con el uso de agregados reciclados
(2019-10-15) Vásquez Vélez, Pablo Andrés; Mogrovejo Carrasco, Daniel Estuardo
The project focuses on the development of sustainable concrete, implementing recycled aggregates as partial substitutes for coarse aggregate. The materials that were recycled and incorporated into the mixtures come from waste from the production process of porcelain and ceramic pieces, just as glass from the collecting of broken bottles of ordinary use is implemented. The materials were duly characterized, and both natural aggregates and recycled aggregates, met the necessary characteristics to be incorporated into concrete mixtures under ASTM C33. Based on the characteristics, an ideal dosage for the tests called standard mixture was determined, it serves as a benchmark and based on it the performance of the other mixtures is quantified. The main objective of the project was to analyze the influence of recycled aggregates on the final strength of concrete, for which the realization of 12 types of mixtures with different components and quantities was defined, with 6 specimens of each. Destructive and non-destructive tests were used on the different concrete elements. The non-destructive test applied was the electrical resistivity, which indicates concrete quality parameters. For destructive tests, compressive strength and indirect tensile strength tests were performed. Curing times for the trials were considered 7, 14 and 28 days. The best performance of the recycled aggregates was that of the porcelain, defining as optimal dosage, which contains 30% natural coarse aggregate and 70% crushed porcelain. This mixture exceeded the final concrete strength of the standard mix reaching 373 Kg/cm2, unlike the other mixtures that reduced its strength by 15 to 40%. Qualitatively, the environmental alternatives contribute up to 60% in the necessary qualification for an environmental certification, and quantitatively it is possible to reduce 690.9 GJ of energy as well as reducing the emission of 47187 Kg of CO2e into the atmosphere.

(2019-04-03) Inga Bacuilima, Dennis Fernando; Paredes León, Celia Cristina; Mogrovejo Carrasco, Daniel Estuardo
The tests used to characterize the fiber reinforced concretes, HRF, are: beam tensile flexure test, EFNARC panel test, circular plate test and the Barcelona double punching test. In the present work, the existing correlations between the bending beam tensile test (ASTM C1609) and the double punching test (UNE 83515) are shown. For this propose, material that was found in quarries near the city was used. In order to find a correlation between both trials, a series of test hypotheses was established, raised by (Aire, Molins, Aguado, & Zárate, 2014), defining the variables that will be evaluated in each trial. These variables are the tenacity measured from the maximum load for the double punching test and the energy absorption for the beam test. In terms of tenacity, an average coefficient of variation of 12% and 16% was obtained for the flexo tensile test in beams for resistances of 350 kg/cm2 and 500 kg/cm2 correspondingly. In contrast, for the double punching test, the coefficients of average variation were 6% and 14% for the resistances mentioned above. In addition, good correlations were found between the tenacity of the double punching test, and the tenacity of the flexo tensile test of beams. The correlations found have a coefficient of determination R2 comprised between a range of 0.899 to 0.998, so it is inferred that the tests are fulfilling the hypotheses proposed.
Determinación de las propiedades físico-mecánicas en mampostería de ladrillo con morteros de junta
(Universidad de Cuenca, 2024-09-17) Lojano Fajardo, Verónica Leticia; Mogrovejo Carrasco, Daniel Estuardo
In the context of the construction development of the city of Cuenca, the materials used date back to various periods, highlighting the use of masonry bricks and both mixed and cementitious mortars. The evaluation of the physical-mechanical properties of these materials is carried out through laboratory tests to identify their characteristics and behavior. This study focused on the use of Portland cement, graded sand and lime in conjunction with brick masonry from Sinincay (Cuenca) and Susudel (Oña). One of the challenges identified in Cuenca is the lack of mathematical models developed to estimate the compressive strength of masonry prisms. The normative framework used included ASTM C109(2016), ASTM C1314 (2021) and ASTM E477 (1997), which guided the execution of the tests. In addition, for the compression tests of bricks and masonry prisms, plywood was used on the top and bottom faces. Several mathematical models were evaluated and the approaches proposed by Hendry and Malek (1986), Bröcker (1963), Bennet et al. (1997), Dymiotis and Gutlederer (2002), Kumavat et al. (2016), Lumantarna et al. (2014) showed consistency with the results obtained in the laboratory tests, providing a solid basis for the accurate estimation of the compressive strength of the prisms with the materials and reality of Cuenca.
