Evaluación del diseño vial urbano utilizando resinas orgánicas para aumentar la capacidad soportante de la estructura de la vía

Abstract

The present investigation comprises the urban road design within the territorial reorganization plan of Sígsig. This design is necessary because the biggest problem for paved roads is the high cost of material, so to make them cheaper, it is necessary to use existing material in the area as well as organic resins to increase the support capacity of the structure of the road.

The material from three different mines was analyzed, the materials were analyzed in natural state and stabilized with cement and with organic resins, changing the CBR variation to stabilize them with different percentages of cement from 1% to 5% and from 0.5 to 1.5 weight for organic resins, and its influence on pavement design.

In order to determine the stresses to which the structure of the road is exposed, a traffic study was carried out by manual counting to determine the TPDA was determined and the AASHTO method was applied for different designs of the pavement structure .

The economic analysis of the different alternatives of the design structure was carried out and compared with the structure with Class 1 Type B base material from the Descanso mine. From an economic analysis it is more economical to carry out road projects in the area with material of the zone stabilized with 3% cement reaching a CBR greater than 80%, complying with the road regulations.
