摘要

Recycled ethylene vinyl acetate (REVA) modified bituminous binders can be used in pavement construction for improved durability and enhanced performance in resisting permanent deformation of bituminous layers. This paper reports the thermogravimetric studies conducted on REVA modified bitumen (REMB) binders. The activation energies were determined from thermogravimetric analysis (TGA) data using Kissinger method, which does not require knowledge of the reaction mechanism. The effect of different percentages of REVA addition, as modifier in neat bitumen on the rheological properties, surface energy and microstructure of the bitumen/ REVA blends has been investigated in this study, which ensured the successful modification of bitumen with REVA.
