Propuesta de diseño de firmes permeables para calles urbanas en la Ciudad de Machala

Abstract

n the present experimental type titration work, a permeable road design is carried out, in order to reduce rainwater runoff in an urban area of the city of Machala. As urban areas increase, the urban drainage system gradually becomes overloaded, with frequent spills into receiving water bodies of contaminated water and uncontrolled flooding in critical areas. The objective is to propose the design of a typical permeable road section for the zones that are prone to flooding in the Machala canton as sustainable alternatives for the control of floods. The methods that were applied for the design according to the AASTHO 93 standard and the methodological design proposed by Castro 2009. The materials for the design proposal are porous concrete using aggregates from the ElColorado Quarry in the city of El Guabo in the Province of El Oro, from which a structure for roads will be proposed, in order to make an optimal design for porous concrete, which due to Due to its physical and mechanical properties, it allows the drainage of runoff waters, thus avoiding water contamination, groundwater recovery and the reuse of rainwater. The strength values for the design were taken as reference in the ACI 522R for the porous concrete layer and should be between 2.8 to 28 MPa. The structure of the permeable road surface contains the following layers i a rolling layer that allows water to enter porous concrete ii a layer of fine granular material, which allows a proper installation of the rolling layer and iii a layer composed of a matrix of large granular material, or of plastic modules or geo-cells where water is stored Subbase. This proposal aims to reduce stormwater runoff primarily by retaining water, stopping, and improving infiltration before entering the drainage system. For the road design, the streets of the Los Ceibos neighborhood were taken as a sample.
