In this paper comparative study on the compressive strength and permeability of pervious concrete with and without fine aggregate is done. Sand and LLDPE (Linear low density polythene) with varying percentages are used as fine aggregates. Sand is added in percentages of 5%, 10% and 15% of the coarse aggregate in all the mixes. LLDPE powder is added in the percentage of 5%, 10% and 15% of the coarse aggregate in all the mixes. With the addition of fine aggregate the compressive strength of the pervious concrete increases but permeability reduces. The results show that the pervious concrete with LLDPE powder there is a considerable increase in compressive strength as compared to no-fines mix and mix with sand as fine aggregate. The study recommends the use of eco-friendly pervious concrete with LLDPE powder as an alternative to the existing pavements with low volume traffic.
