Evaluation of Warm Mix Crumb Rubber Modified Asphalt Mixture (WCRMA) on resisting permanent deformation

Abstract Crumb rubber (CR) is generated from the recycling of used or discarded car tires and has long been utilized in paving industry. can be asphalt mixes two ways: dry process wet process. However, compared to standard combinations, crumb modified (CRMA) requires much higher mixing compaction temperatures. As a potential substitute, using warm mix (WMA) technology significantly lower hot-mix (HMA) production placement temperatures through viscosity reduction. In accordance, objectives study are produce rubberized mixtures (WCRMA) evaluate WCRMA’s performance terms rutting resistance. WCRMA produced by adding 1, 3, 5% Sasobit® total weight binder. The was evaluated Dynamic Creep test. result showed that with largest percentages (5%) lowest accumulated strain permanent deformation. mixture performed better had greater resistance due replacement fine aggregate addition control sample.
