Abstract
AbstractThe main purpose of this article is to evaluate the correlation between the indirect tensile strength and the permeability capacity of porous concrete (PC) pavements. The compaction method ...
Highlights
Cities have played a very important role in human development for centuries, as they concentrate the main economic activities, industry, resources, and waste and emissions generation (Sinha et al 2002)
This study evaluates five different compaction methods, with different procedures applied to the mixtures, in order to estimate the effects they have in terms of indirect tensile strength and permeability
The p-value corresponds to a onetail analysis, where the hypothesis is the probability of obtaining a value, μ, higher than 1.20, for the indirect tensile strength, and higher than 0.012 for the permeability
Summary
Cities have played a very important role in human development for centuries, as they concentrate the main economic activities, industry, resources (as well as their consumption), and waste and emissions generation (Sinha et al 2002). Water gets polluted because the natural water cycle is interrupted by the impermeable barrier formed by roads and buildings, where water cannot infiltrate through the natural soil, instead reaching city pavements, which causes runoff and adds pollutants (Rodriguez-Hernandez et al 2013). As part of the solution, porous pavements have gained increasing attention, since they are able to infiltrate rainwater into the ground, recharging the aquifers, or enabling water to be saved for other uses such as agriculture or human consumption (International Water Association 2017; Rodriguez-Hernandez et al 2013). These pavements consist mainly of asphalt or cement concrete. Different studies have been done around the world, and the implementation of these materials depends mainly on the characteristics of the place where they are being deployed (Alvarez, Martin, and Estakhri 2011; Tennis, Leming, and Akers 2004)
