A Review of Porous Concrete Block Pavement for Heavy Rainfall

Abstract

In recent years, the popularity of porous concrete block has grown in the industry but there is still lack of knowledge on how and when porous concrete block is appropriate. The objectives of this paper is to presents and study a pre-view of porous concrete block used for pavement by using different size of aggregate and effect of permeability on porous concrete block during heavy raining season. Large volume of surface water runoff needs to handle during this season to prevent water ponding on the roads surface. Porous concrete blocks has proved to be effective and meet most of the requirement to solve the problem. The investigation on the different size of aggregate use in porous concrete block and its performance is very limited. However, further researches are ongoing by the authors to study performance of porous concrete block for pavement in mechanical and chemical properties will evaluate. Various tests were carried out to evaluate durability of porous concrete block made with 10 to 8 mm and 8 to 5 mm size of aggregate in concrete mix. On the other hand, the results of compressive strength, porosity and clogging test from previous investigation were present in this study.
