The Porous Concrete for Rigid Pavement

Roads play an important role as a connection between locations and can facilitate the efficient mobility of people's economic activities. Five tests are involved in evaluating of the porous concrete, such as the slump test, compressive strength test, permeability test, flexure test, and load capacity test (loading test). Meanwhile, there are three types of soil: peat, clay, and hard. The compressive strength test measured an average compressive strength between 24.17-27.36 MPa. According to the permeability test, the average speed of water infiltration on the porous concrete rigid pavement was 20 seconds on clay soil and 55.344 seconds on peat soil, with large areas drained on porous concrete rigid pavement of 346.185 cm² with 5 litres of water used, whereas it was 6.554 seconds with a flow area of 288.75 cm² and 2 litres of water used on hard soil. The Loading Test was conducted with a 10-ton. The maximum difference in deflection was 1-2 cm. In addition, there were no cracks in the porous concrete rigid pavement with a porous concrete rigid pavement thickness of 15 cm in three different soil conditions. A track with porous concrete rigid pavement on clay, hard soil, or peat soil can accommodate a maximum payload of 10 tons.
