An experimental study was conducted to evaluate the effect of compaction layer configuration, effort, and blow pattern on compressive strength and porosity characteristics of pervious concrete. Distinct types of compactions were applied to pervious concrete mixes with aggregate-to-cement (A/C) ratios ranging from 2.5 to 7.0. The results obtained from the experimental study revealed that three-layer compaction improved compressive resistance significantly compared with single-layer. In contrast, reduction in porosity was observed in three-layer compaction. Overall, by optimizing compaction effort and A/C ratio in three-layer compaction, compressive strength and porosity could be improved to be in the ranges 20.0 MPa to 30.0 MPa and 15% to 35%, respectively. In the three-layer compaction configuration, blow patterns have been identified to influence compressive strength and porosity. Findings of the study recommend deploying an A/C ratio between 3.5 and 4.5 with three-layer compaction to cast pervious concrete that would produce elements with compressive strength and porosity ranging from 10.0 MPa to 25.0 MPa and from 11% to 30%, respectively.
