Increasing the Stability of Asphalt Concrete Mixture Using Crumb Rubber

Stability is a measure of the strength an asphalt mixture in resisting deformation due to loading. If road construction structure cannot withstand existing load, it will result damage that endangers users. This study aims improve stability concrete with use crumb rubber. Crumb rubber used because has good resistance and elasticity. The research was conducted experimentally by making test objects laboratory. In this study, five variations (2%, 4%, 6%, 8%, 10% weight mixture) were carried out size powder retained on 40 sieve. Marshall analysis volumetric determine characteristics asphalt-concrete mixture. results showed highest obtained at value 1422 kg. can significantly increase quality Thus, be used, percentage as reference manufacture mixtures order obtain pavement quality.
