Investigation of the effect of various additives on the strength of environmentally friendly permeable concrete

Abstract

Over recent years the development of one Water Sensitive Urban Design technology, known as permeable pavement has been researched to potentially eliminate the majority of runoff issues associated with road surfaces. Permeable pavements perform the dual functions of supporting traffic and of stormwater management. This paper aims to develop a new type of permeable concrete pavement material with enhanced compressive strength while maintaining its permeability. A series of laboratory testing have been conducted to evaluate the structural strength and permeability of various mixture designs of permeable concrete. The effects of adding different supplementary additives as well as applying two different layers have been discussed in details. The additives used in this project are silica fume, fly ash, and polymers. The associated failure pattern with each different mix design has also been discussed.
