Diseño de pavimento permeable, a través de ensayos de diversas dosificaciones, para condiciones de tráfico pesado

Abstract

Several areas of Guayaquil are vulnerable to flooding due to insufficient drainage systems. In this context, this project proposes the design of a high strength pavement, and permeable by incorporating holes in the concrete slab based on defined porosity. This solution aims to strengthen flood resilience while promoting urban sustainability. The methodology included mechanical tests like compressive and flexural strength, permeability tests, and grading tests conducted according to ASTM Standard 2023, complemented by the calculation of IDF curves and retention efficiency, as well as pavement design according to AASHTO 93 using modeling software. The results show that the mixture with 5% rubber replacing the fine aggregate achieved a compressive strength of 58.7 MPa, a flexural strength of 5.6 MPa, and with a porosity of 2.8%, a retention capacity between 4% and 30% was obtained. These performances prove that the permeable pavement designed for high traffic studied has enough capacity to infiltrate to the stormwater system, consequently reducing the risk of flooding without compromising the load-bearing capacity of the concrete.
