Diseño de prototipo de pavimento mediante un análisis comparativo de vías urbanas en zonas regeneradas de la ciudad de Machala

Abstract

The city of Machala is characterized for having roads in constant deterioration. However, this problem is not only localized in one city, practically the world's population suffers the consequences of damage to the roads they use daily. The increase in traffic volume, the territorial reordering for commercial zones, as well as terrible road constructions that prioritize cost reduction without taking into account the useful life of the work are just some of the aspects to take into account when designing a pavement. Due to the need to satisfy these situations, the creation of new pavement structures has become a matter of public interest. Therefore, this report tries to solve this problem by designing a pavement prototype, based on an exploratory analysis of several urban roads in the city of Machala and the search for international models that served as a comparative method of characteristics of an ideal pavement. Once the models were established, three in this case, the flexible structure with asphalt wearing course was chosen due to its reduced cost, quick application in situ and its high service life (20 years) exceeding the average local periods of 10 to 15 years. Its structural conformation consists of three layers: a wearing course of a 5 cm thick high-stiffness asphalt mix, a 15 cm thick base of granular material with fly ash, and a 23 cm sub-base of lime-stabilized soil.
