The modification of bitumen with synthetic reactive ethylene terpolymer and ethylene terpolymer

Abstract

The aim of this study is to improve features of 60/70 penetration grade modified bitumen used on highways. A new asphalt compound has been formed by an additive to decrease sensitivity to temperature and to increase resistance of bitumen. As additives, synthetic reactive ethylene terpolymer (SRETP) and ethylene terpolymer (ETP), which were recommended by DuPont, have been added in bitumen and made some trials. Infrared (IR) graphics and optical pictures of the modified bitumen have been examined and after analysis of the tests, a clear increasing at softening point but decreasing in penetration and ductility values have been observed as a result.
