Pervious Concrete Utilized as a Base Slab of Pavement Edge Drains
The drainage base plate is generally made of normal concrete. The application of pervious concrete as base-slab of pavement edge drain will then be possible to infiltrate storm water runoff on the pavement surface that is not infiltrated through the pavement surface. The edge drain does not only accommodate storm water flow, but also transmits water to the ground so that it can restore the ground water level or can be reused through a reservoir in the ground underneath. The effectiveness of the application of pervious concrete as a drainage base plate on silt-clay soils was conducted experimentally. The thickness of the porous concrete slab in the modeling box is 7 cm, laid above 20 cm height of silty clay soil layer. Reference soil conditions as well as contours and cross-sectional characteristics of the edge drain are taken based on the condition of one of the existing drainages in West Bandung. Based on the results of numerical simulations using Geostudio SEEP/W, it can be seen that there is an increase in pore water pressure in the area of the pervious concrete slab and the surrounding soil. The pore water pressure at the bottom of the plate is in the range of 18.64 kPa. Overall, the pore water pressure in the first modeling tends to be higher than in the second modeling. On the third day of testing, the difference in pore water pressure between the two modeling conditions is 27.08%.
