Abstract

Continued urbanization in the Greater Jakarta area has caused a narrowing of the catchment area due to land use focused on housing and office development. The use of porous concrete as a road pavement can be a remarkable potential to counteract this problem, allowing rainwater to penetrate the concrete, thus reducing runoff and increasing the groundwater level. The study aims to analyseporous concrete's mechanical properties by looking at the influence of porosity level of concrete by 15% and 20% and the impactof maximum size aggregateused by 10 mm and 20 mm. This study's mechanical properties include compressive strength, splitting strength, flexural strength, and shrinkage of porous concrete. The results show that porous concrete with an aggregate size of 10 mm has a splitting tensile strength and flexural strength greater than the 20 mm and a shrinking process faster than the 20 mm. Besides, porous concrete with a porosity level of 15% has compressive strength, splitting tensile strength, flexural strength more significant than 20%, and the shrinkage process faster than 20%. Finally, this study proposed a design recommendation on porous concrete for low traffic pavement. Based on the soil and rain data in Depok City, this study recommends 200 mm thickness of porous concrete layer, 225 mm thickness of subbase layer, HDPE pipe with 100 mm diameter, and 0.38 mm thickness of the impervious liner. Further research on the porous concrete design based on field study is urgently needed to prove the recommended design.
