Abstract

AbstrakPeningkatan pembangunan infrastruktur mengakibatkan perubahan tata guna lahan yang meminimalkan laju infiltrasi dan meningkatkan limpasan permukaan. Dibutuhkan alternatif penanganan yang tepat dalam mengatasi genangan air yaitu dengan penggunaan beton porous sebagai tutupan lahan. Limbah beton dimanfaatkan dalam pembuatan beton porous sebagai pengganti agregat kasar, yang disebut Recycled Coarse Aggregate (RCA). Untuk mengetahui kemampuan beton porous dalam mengatasi limpasan air pada permukaan miring dilakukan penelitian mengenai pengaruh kemiringan beton porous dengan agregat daur ulang terhadap kemampuan infiltrasi dan permeabilitasnya. Pengujian infiltrasi dilakukan pada kemiringan horizontal 2% dan kemiringan vertikal 0%, 10%, 20%, 30% menggunakan standar ASTM C 1701/C 1701M – 09. Dari hasil pengujian yang dilakukan, diketahui bahwa kemiringan vertikal dan horizontal beton porous mempengaruhi kemampuan infiltrasinya. Laju infiltrasi pada beton porous semakin berkurang seiring dengan bertambahnya kemiringan vertikal. Jenis agregrat juga diketahui mempengaruhi kemampuan permeabilitas beton porous. Beton porous dengan recycled coarse aggregate (RCA) memiliki kemampuan permeabilitas yang lebih besar dibandingkan dengan beton porous dengan natural coarse aggregate (NCA).AbstractIncreased infrastructure constructions have resulted in land-use change which minimizes water infiltration into the soil and increases the amount of surface runoff. An alternative solution is needed to handle puddles, which is by using pervious concrete as land cover. Concrete waste is used as a substitute for coarse aggregate, which is called Recycled Coarse Aggregate (RCA). To determine the ability of pervious concrete to overcome water runoff on sloping surfaces, a study was conducted to identify the effect of the tilt position of pervious concrete on its infiltration rate and permeability. The infiltration test is carried out with a 2% of horizontal tilt and 0%, 10%, 20%, 30% vertical tilt following the procedures of  ASTM C 1701/C 1701M – 09. Based on the results of the research, it can be concluded that the vertical and horizontal tilt position on previous concrete affects the infiltration rate. And the type of aggregate does affect the permeability of pervious concrete, pervious concrete with recycled coarse aggregate (RCA) has greater permeability than pervious concrete with natural coarse aggregate (NCA).
