Abstract

This study investigated the fatigue properties of organo-montmorillonite modified bitumen mortar. Organo-modified montmorillonite(OMMT)with a content of 5 wt% was used to modified one base bitumen mortar which consist of filler and bitumen at a weight ratio of 0.8:1. The fatigue properties of these bitumen mortars have been determined using a dynamic shear rheometer(DSR)through time sweep test. Result indicated that, due to the addition of the OMMT, the fatigue properties of modified bitumen mortar was superior to those of pristine mortar. Therefore, the OMMT would be an alternative to modifiers used in the bitumen to improve the lifetime of asphalt pavement. Meanwhile, some fatigue equations were estabilished.
