Application of Pervious Concrete Principles on U-Ditch Covers in Overcoming Puddles

Based on data released by the Badan Metereologi dan Geofisika (BMKG), the average rainfall rate for Medan City in 2020 reached 9,907 mm in accumulation. The use of asphalt or concrete on most roads results in puddles and even floods often occur because concrete or asphalt has a smooth surface so that it is not able to infiltrate into the ground properly and results in larger surface runoff. For this reason, a research has been carried out on the application of Pervious Concrete principles on U-ditch covers with an experimental method that utilizes sidewalk’s paving block waste. This research was conducted by varying the addition of sidewalk’s paving block waste as much as 3 variations in composition, i.e.; 10, 20 and 30%. The results obtained that the optimum composition in the application of pervious concrete on u-ditch covers which was effective and capable of draining water was variation I (10% addition of paving block waste.). With a compressive strength of 8.862 MPa; split tensile strength of 1,556 MPa; flexure strength of 2.453 Mpa and infiltration rate of 1.93 × 10–4 mm/h. And u-ditch covers in this research had a good infiltration value so that rainwater runoff could be passed to the drainage.
