Abstract : Pervious concrete is one among the evolving sustainable pavement materials due to its unique storm water storage and ground water recharge applications. The present study aims to develop a Pervious Interlocking Paver Block (PIPB) and to study its mechanical, functional and structural performance. In the current explorative research work, the influence of aggregate gradation, and the percentage of fines on mechanical, functional and structural performance of PIPB were evaluated. The mechanical and functional properties such as compressive strength, split tensile strength, flexural strength, and skid resistance are assessed. The structural behaviour of the PIPB pavement section is found using plate load test and large-scale direct shear test. FEM based software, PLAXIS, is used to validate the test results. Infiltration test is conducted on the plate load test section to understand the infiltration rate. Finally, 2D image processing was performed using MATLAB to conclude the test findings. The test results proved that the grade III mix possesses desirable mechanical properties, lower deflection, higher shear strength, and required permeability. The present study affirms that the PIPB can be an effective pavement material for the low volume roads, urban heat island and pavements with drainage problems.
