Análisis comparativo de las propiedades físicas de mezclas drenantes para la aplicación en la construcción en pavimentos asfálticos

Abstract

This document refers to a wide bibliographic content of scientific articles, based on design criteria of draining asphalt pavements, which allows addressing the different problems that arise such as, traffic accidents due to hydroplaning caused by water puddling on the roadway, noise generated by the contact between tire and traditional pavement, soil contamination and wastewater,. The objective to be achieved is a comparative analysis of the physical properties of draining mixtures for the application in the construction of asphalt pavements, highlighting a porosity of 20 to 25%. This research assumes a methodology based on international design parameters for the construction of permeable asphalt pavements such as, type of mix, air voids, maximum nominal size, type of asphalt, voids in mineral aggregates, voids filled with asphalt, asphalt content, compaction methods, Cantabro loss, drainage, thickness of the wearing course. However, in this research it is determined that the most competent designs to achieve our objective are the designs presented in the countries of Costa Rica and Malaysia, with air voids of 21%, asphalt contents of 5.6% and 5% respectively, type of mixes used based on cellulose fibers and hydrated lime, achieving a reduced permeability of 0.15% and a wear loss of 21.5% in the design of the draining asphalt pavement.
