γ-(2,3-Epoxypropoxy)propyltrimethoxy silane surface modified layered double hydroxides (KH560-LDHs) were prepared and used to improve the ultraviolet ageing resistance of asphalt. The results of X-ray photoelectron spectrometry (XPS) indicated that KH560 has been successfully grafted onto the surface of LDHs. The agglomeration of LDHs particles notably reduced after KH560 surface modification a...

Using waste rubber in asphalt mixes has become a common practice in road construction. This paper presents the results of a study on the rheological characteristics of rubber-modified asphalt (RMA) concrete under static and dynamic loading conditions. A number of static and dynamic creep tests were conducted on RMA mix specimens with different rubber sizes and contents, and a series of resonant...

Construction of flexible pavements with hot mix asphalt (HMA) mixtures consumes huge energy which impacts the resources and the environment of the world. Warm Mix Asphalt (WMA) is an effective alternative as they produced with lower mixing and compaction temperature than those used in HMA production. This technology decreases energy consumption, saves money, and reducing the environmental pollu...
