The increase of traffic volumes on the roads consequently increases the tyre pressures and produces heavier axle loads imposed on pavement structure. Hence, there is a need to enhance asphalt pavement mixtures that may prone to rutting, to withstand the increase traffic loading, mitigate adverse effects on pavement performance and reduce thermal pavement cracking. Therefore, it is important to study material such as reclaimed rubber that has a potential to be admixture in hot mix asphalt. In this study, old car tyre tubes were used as an admixture in hot mix asphalt. The reclaimed rubber were cut into various sizes to determined the effect of different size used. This study shows that size of rubber can affect the performance of reclaimed rubber modified asphalt mixes (RRMAM). Small size reclaimed rubber can provide more stability than bigger size of reclaimed rubber.
