Metodología para evaluación de pavimentos flexibles de vías urbanas, estudio de caso Ciudad de Pasaje año 2020

Abstract

According to the Territorial Development and Planning Plan PDOT of the Decentralized Autonomous Government GAD of the Pasaje Canton, it registers 56.64 kilometers of urban roads with flexible pavement, in which no evaluations have been carried out that allow knowing the surface and structural state from the pavement. The humid climate and traffic are key factors to induce and accelerate the deterioration of the flexible pavement González-Fernandez et al., 2019, in the study route there are rainfall that varies from 500 to 1500 mm / year, being the months of highest incidence January to April, therefore, it is important to implement an evaluation methodology that allows knowing the state of the pavement. The general objective of this research is to carry out the superficial and structural evaluation of flexible pavements in urban roads to identify the level of deterioration and the structural state that it presents, for this purpose, the Pavement Condition Index Method PCI will be used, a procedure visual inspection that is used to evaluate surface level deterioration, identifying and classifying them according to quantity and severity, and, for structural evaluation, the Impact Deflectometer FWD is used, state-of-the-art equipment that allows to know the deformations of the pavement produced by a load that simulates the action of traffic, in order to characterize the structural condition of the pavement-subgrade through correlations. Finally, as a result, a methodology is proposed to guide the criteria and steps to be considered in the superficial and structural evaluation of flexible pavements of urban roads
