Plan de intervención vial en base a la evaluación del PCI (Pavement Condition Index), caso de estudio Quinta Chica Baja, Cuenca-Ecuador

Abstract

This thesis develops a road intervention plan for the municipality of Quinta Chica Baja, east of the city of Cuenca, province of Azuay, Ecuador. The intervention plan is based on the functional evaluation of the rigid and asphalt pavement, considering the implementation of two methods; the first according to the ASTM D6433 standard regarding the determination of the Pavement Condition Index (PCI), and the second considering the Markov chain technique. The determination of the PCI is carried out on 76 sample units distributed in 15 sections. Two procedures are considered: a manual one and a computational one using the program PAVER. On the other hand, the projection of the future pavement condition is evaluated using Markov chains for preventive, corrective, overlay, rehabilitation or reconstruction interventions. The results obtained on PCI for the asphalt pavement show that 22.85% are currently in good condition, 43.24% are in fair condition and 33.91% are in poor condition requiring pavement rehabilitation and overlay from a functional point of view. The results for the rigid pavement show that 100% are in excellent condition and only preventive maintenance is required. Finally, based on the results of the functional assessment at the section level and the types of defects found, as well as the procedures to be followed and the associated costs, an intervention plan was prepared for each of the study sections. It is recommended that the intervention at the level of defects be carried out as soon as possible, as this would involve lower investment costs and improve the level of passability of the sector
