A Review of Double Layer Rubberized Concrete Paving Blocks

Abstract

The objective of this paper is to presents and study a review of waste material i.e. tyre rubber granules as a partial aggregate replacement in different percentage and size of rubber granules; and different thickness of block layer. Waste tyre rubber is found to be very high in toughness. Owing to its technological and economical advantages, both strength and toughness of concrete can be increased. Incorporation of waste tyre rubber granules as aggregates in concrete mixture not only improves the toughness of concrete, but also improves the acoustics element by the increase of sound absorption level. Previous studies on rubberized concrete paving blocks (RCPB) especially on ability of pavement to absorb sound is very limited. Various tests will be carried out to evaluate engineering properties of double layer RCPB with 10, 20, 30, and 40% replacements of waste tyre rubber granules by weight of aggregate. The sound absorption level of double layer RCPB with different thickness of layer will be studied.
