【 摘 要 】

Based on its geographical location, Indonesia is a country with high annual rainfall that causes the country to face a number of environmental problems, especially in urban areas. Reduced catchment areas due to changes in land use into residential and industrial areas, causing surface runoff problems and groundwater level declines. The use of pervious concrete as an alternative to environmentally friendly pavement can overcome these environmental issues. Nevertheless, pervious concrete has low strength due to weak bonding between aggregates as pervious concrete uses little or no fine aggregate so that it is only fastened by paste and produces voids between aggregate. Styrene butadiene rubber (SBR) latex was proposed in this study to improve bonding between aggregates and increase the strength of pervious concrete. 0%, 5% and 10% SBR latex by weight of cement were added in pervious concrete mixture to investigate the effect of SBR latex to the strength and permeability performance of pervious concrete to drain stormwater into the soil. Recycled coarse aggregate also used in the experiment to promote sustainable construction. The results showed that SBR latex increased the compressive strength of pervious concrete. However, the use of SBR latex also decreased the void ratio and permeability of pervious concrete.
