Abstract
Concreting everywhere leads to environmental issues such as reduction in the discharge, which makes the life at major cities miserable. The solution to minimize this problem is by installing pervious concrete pavements instead of impervious concrete or asphalt pavements for low volume traffic areas. This paper explains in detail about the use of pervious concrete as pavement material. In this study, we considered mix proportion of pervious concrete from reference mix of M40 in that by changing the fine aggregate content to 0-18% by replacement method. i.e. the fine aggregate volume is replaced by coarse aggregate volume in mix proportion, there will be no change in volume of aggregate hence we had difficulty in finding volume of cement paste occupying volume of voids, because volume of aggregate and volume of cement paste will be constant in proportions ,therefore we found relationship of varying fines with permeability , porosity(without cement paste) , failure load and compressive strength . As it satisfies the criteria of using it of sub-base for concrete pavement as permeable and dry lean concrete sub base.
