Abstrait:

Pakistan is facing adverse environmental issues peculiarly in major cities. The condition gets worst during monsoon period when the whole city faces the urban flooding due to stagnation of storm water on all major streets and areas. The main reason is the lack of infra-structure to mitigate the crisis which is faced by the country during whole rainfall season. The introduction of Pervious Concrete in major pavement infra-structure can easily limit the problems of sump of rain water. As a part of road infrastructure, the upper layer of pavement can be pervious, making runoff water to move to sub-base. This paper offers the exploratory research to ascertain the compressive strengths and infiltration rate of different samples of Porous Concrete following the American Concrete Institute guidelines. The experiments were done with varying the properties of Pervious Concrete. The effects which were considered are curing time, mix proportion, percentage quantity of fine aggregate, ratio of water to cement and varying coarse aggregate size. The mix design ratio considered were 1:4, 1:5 and 1:6. For further experiment of infiltration rate, the custom slab was formed with dimensions 2’x1’x4” and was tested for all the desired ratios. For the purpose of cost comparison, a fixed size on land is kept as standard. The cost is compared for construction on the land, using three different materials:   Pervious concrete,   Traditional concrete and   Asphalt premix.It was showed that the Traditional concrete is cheaper than the Pervious and Asphalt layer but Pervious concrete is also economical than Asphalt layer.
