The objective of this paper is to presents and study a review of waste material i.e. rubber granules as a partial aggregate replacement in different percentage and size of rubber granules; and different thickness of block facing layer. Tyre is designed to be very high in toughness and owing to its technological and economical advantages, both strength and toughness of concrete can be increased. Incorporation of 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 low-noise concrete paving blocks are very limited. Physical, chemical and mechanical test will be carried out to evaluate properties of double layer rubberized concrete paving blocks (DL-RCPBs) with 10, 20, 30, and 40% replacements of RG by weight of aggregate and the blocks aredesigned with 10 mm, 20 mm, 30 mm and 40 mm of facing layer thickness. The sound absorption level and noise reduction coefficient of DL-RCPBs with different thickness of facing layer will be studied.
