This paper presents a study on the investigation of waste tyre rubber (rubber granule) as aggregate in the production of concrete paving block (CPB) with double layers. A series of tests were carried out to determine the properties of double layer rubberized concrete paving blocks (DL-RCPB). In this study, there are four series of concrete mix with 10 %, 20 %, 30 % and 40 % of waste tyre rubber replacement level. The dimension of CPB was 200 mm x 100 mm x 80 mm with 20 mm thickness of facing layer. The results showed that the percentage of waste tyre rubber content for DL-RCPB affects the density, porosity and compressive strength. The control concrete paving block (CCPB) and DL-RCPB (10 %) achieve the minimum strength requirement of 45 MPa. The density of DL-RCPB (40 %) recorded reduce 24 % as compared to CCPB. At 28 days, the percentage of porosity increased up to 55 % when 40 % of aggregate were replaced with rubber granule. The skid resistance of concrete block increased by 7 % with the incorporation of rubber granule particle size of 1 - 4 mm and 5 - 8 mm up to 40 % as the replacement of fine aggregate and coarse aggregate, respectively.
