Newer technologies such as warm mix asphalt (WMA) and reclaimed pavement (RAP) have gained international approval been considered appropriate solutions that support the sustainability goals of highway sector. However, both present some shortcomings. The lower mixing compaction temperatures WMA reduce binder aging bond between aggregates coating binder, thus resulting in less rutting resistance ...

Abstract The application of polymer in an asphalt concrete (AC) mixture has reached wide popularity lately to deal with the increasing demand for higher quality roads heavier traffic loading. Ethylene-vinyl acetate (EVA), classified as a thermoplastic, is currently one most popular polymers employed. This research attempts evaluate effect adding EVA by means dry method, namely pouring additive ...

An immense problem affecting environmental pollution is the increase of waste tyre vehicles. In an attempt to decrease the magnitude of this issue, crumb rubber modifier (CRM) obtained from waste tyre rubber has gained interest in asphalt reinforcement. The use of crumb rubber in the reinforcement of asphalt is considered as a smart solution for sustainable development by reusing waste material...

pavement permanent deformations due to lack of shear strength in mixture are a major reason of rutting. any simple test to determine mixtures resistance to permanent deformation isn’t distinguished in the 1st level of superpave mix design method and prevalent methods for evaluating mixture rut resistance are expensive and time-consuming. two aggregate types, gradations, asphalt cements and fill...
