Abstract: Deterioration of highway pavement resulting from flooding is on the increase because of climate change. Previous researches have succeeded in removing the run-off water using pervious concrete but for low traffic density. This research focused on improving the structural performance of pervious concrete for high-density traffic. The 168 test samples of pervious concrete comprising of 54 beams, 54 cubes and 60 cylindrical specimens were cast to undergo slump test, density and void content test, split tensile strength test, flexural strength test, compressive strength test and permeability test. Sawdust ash was added to replace cement with varying percentages of 5, 10, 15 and 20. The result shows that varying percentages of 5, 10, 15 and 20 sawdust ash mix exhibit poor mechanical properties.
