This study examines the effect of addition of steel fibers on mechanical properties and permeability of pervious concrete (PC) for application in low volume roads. The PC mix was doped with hooked end (4-D) and crimped steel fibers with aspect ratios of 67 and 50 respectively in different percentages, i.e., 1%, 1.5%, and 2% by volume of concrete supplemented with a comb polymer super plasticizer. The test results confirm that PC with 1.5% hooked end (4-D) steel fibers showed the maximum increase in compressive and flexural strengths by 7.5% and 21.5% respectively over the control mix while maintaining adequate permeability. The improved flexural strength was later used for structural and hydrological design of pervious concrete pavement (PCP). The inclusion of hooked end (4-D) steel fibers in PCP reduced the slab thickness by 25 mm when compared to conventional PCP.@en
