Evaluación de la influencia del espesor de una carpeta asfáltica porosa, en la infiltración del agua superficial de una vía

Abstract

The deterioration that suffer the pavements asphaltic is caused by heavy rainfall that cause of traffic accidents and damage to the road, so new construction technologies promote the use of drainage asphalt pavement, which provide an efficient evacuation of water in the road by means of the permeability, providing to the users a good stability between the tire and the road, avoiding the splash and the hydroplane. The present study aims to evaluate the incidence of the thickness of the drainage asphalt layer during the evacuation rainwater, through the elaboration of tiles of 50x40 cm with thicknesses of 2 ", 3" and 4 "and the use of variable load permeameter LCS, obtaining as results the time of infiltration, coefficient of permeability K, infiltration rate and calculation of the Reynolds number. It was also used a computational fluid dynamics (CFD) program modeling a section of the drainage mixture of thickness of 4¨, validating the average velocity of infiltration.
