Issue of rubber additive in asphalt mixture has been discussed in asphalt industry Malaysia and its usage was suggested to be used in Pan Borneo Highway project. Using rubber additives can increase revenue rubber tappers in Malaysia. Hence, a study was conducted by the Public Works Department (PWD) and Malaysian Rubber Board (MRB) to investigate the properties of Cup Lumps Modified Asphalt (CMA) based on PWD specifications and its performance. The study area selected was at FT02, Jalan Kuala Lumpur - Kuantan, Temerloh Pahang. In this study, 5 % Cup Lump Modified Binder (CMB) were used. Tests involved were Penetration Softening Point, Flash Point, Dynamic Shear, Marshall, Road Scanner (RS), Falling Weight Deflectometer (FWD), Skid Resistance (Pendulum Test) and Dynamic Creep. The results indicate that CMB with bitumen 60/70 meet the specification. However, it will tend to rut when the temperature exceeds 70°C. For CMA mixture, it shows similar performance with conventional mixture. Meanwhile, at site, the performance for CMA pavement was better in surface condition (94 % good condition in roughness), structural condition (100 % good condition), skid resistance (SRV 63) and dynamic creep (32.01 MPa) compared to conventional pavement AC14. Thus, it can be suggested that the performance of CMA is better than conventional mixture AC14.
