Effect of various combinations of aperture diameter and pattern on concrete paver block

Abstract

In the heavy Rainfall areas water – logging on roads is the main cause for the early damage of roads, which requires frequent maintenance. In the permeable concrete block pavement (PCBP), through joints water is percolated with that reducing storm water runoff, urban heat island effects, and increasing groundwater recharge. To increase the rate of infiltration in PCBPs, concrete paver block (CPB) with an aperture was developed. To study the effect of aperture, an experimental program was conducted on CPBs with different combinations of aperture diameter and pattern, by keeping aperture area as constant. These blocks were tested for compressive strength, split tensile strength and water absorption. In CPBs, for different combinations of aperture diameter and pattern, there was no significant change in compressive strength and water absorption values. Split tensile strength of CPBs was impacted adversely with increase in the number of apertures, to improve this property appropriate aperture pattern should be adopted.
