Nanoclay-modified asphalt mixtures for eco-efficient construction

S. Ghaffarpour Jahromi and Shahid Rajaee,     Teacher Training University, Iran

Abstract:

Polymeric nanocomposites are among the most exciting and promising classes of materials discovered recently. A number of physical properties are successfully enhanced when a polymer is modified with small amount of nanoclay on condition that the clay is dispersed at nanoscopic level. In this research, comparative rheological tests on binders and mechanical tests on asphalt mixtures containing unmodified and nanoclay modified bitumen were carried out. Two types of nanoclay were used: Nanofill-15 and Cloisite-15A. Rheological tests on binder were penetration, softening point, ductility ...
