Asphalt cements are often regarded as a colloidal system containing several hydrocarbon constituents: asphaltenes, resins, and oils. The high molecular weight asphaltene particles are considered to be covered in a sheath of resins and dispersed in the lower molecular weight oily medium [Whiteoak (1990) The Shell Bitumen Handbook (Shell Bitumen UK, Riversdell House, Surrey, UK)].

Experimental and Simulation Study of Phase

The evolution of morphology at the microscale of polymer-modified asphalt under thermal conditions is of interest due to its great influence on the macroperformance of asphalt. In this paper, a phase-field method is presented to model the evolution of microstructure and storage stability of ethylene-vinyl acetate (EVA)-modified asphalt.
