The infiltration capacity of eco-concrete paving on different block shapes

Abstract

Abstract The study evaluates the infiltration capacity of the three eco-concrete paving block types, they are the three-diamond, the S, and the straight pavers. The objective of the study is to evaluate the infiltration capacity of those paving block types in different scenarios of slopes in high rainfall intensity. This research is carried out in the laboratory with some boundaries, namely: paving blocks used are 80 mm thick, gaps between pavers is 5 mm wide, the bedding layer thickness is 100 mm, the slopes of the test field are 0%, 2%, and 4%, rainfall intensities is 275 mm/hour. A box model for the infiltration capacity test was developed with a size of 1m 2 , which is equipped with a modified rainfall simulator. The main conclusions of this study are: (a) Each paving shapes shows different infiltration capacity characteristics; (b) The infiltration rate of pavement is strongly influenced by paving shapes; (c) The slope gradient increases, the volume of infiltrated water decrease; (d) The trihex type gives a better infiltration characteristic than that of the uni page and the rectangular types.
