摘要: The rheological properties of various polymer modified bitumens were studied. Three from two different sources mixed with styrene-ethylenbutylene-styrene (SEBS), ethylene vinyl acetate (EVA) and butyl acrylate (EBA) copolymers at contents. the binders investigated by means dynamic mechanical analysis creep test (bending beam rheometer). results indicated that modification increased binder elastic responses moduli intermediate high temperatures, reduced complex stiffness low temperatures. Polymer also temperature susceptibility, glass transition as well limiting temperature. degree improvement generally content, but varied bitumen source/grade type.
