Pervious concrete pavements are considered one of the well accepted stormwater management strategies as per environmental protection agencies. The interconnected pore structure in the pervious concrete allows the stormwater to percolate and thus reduce the runoff.


The laboratory and field investigations on the pervious concrete pavements have shown that the abrasion and clogging are major distresses that reduce the functional performance of these sustainable pavements. The open graded structure of the pervious concrete undergoes ravelling due to vehicular movement and they may also allow the suspended particles in stormwater runoff to get clogged inside the pore structure. In this study, 2-layered pervious concrete was designed to balance the trade-offs between strength and durability. The porosity and density of 2-layered pervious concrete were found to be in the domain of conventional pervious concrete.


The failure pattern in compression indicated that the failure of the specimen was concentrated on the bottom layer compared to the top layer. Further, the compressive strength was found to be in the range of 11.90 to 20.0 MPa. The pore distribution at the interface of the top and bottom aggregate was found to follow 3-parameter Weibull distribution, where the scale parameter increased as the aggregate size increased. The abrasion resistance was found to be lower compared to conventional pervious concrete.


Overall, it was found that 2-layered pervious concrete can be one of the alternatives to implement pervious concrete pavements addressing the demerits of conventional pervious concrete.
