Abstract
It has been well established that the rheological properties of the asphalt cement binder affect the pavement performance. In this paper 80/100 penetration grade of asphalt cement binder is modified by using of Oil Palm Fruit Ash (OPHASH) as modifier. The mixture is called OPFASH-Modified Asphalt Cement (O-MAC). Two parameters namely Penetration Index (PI) and Penetration-Viscosity Number (Pen-Vis Number or PVN) are used to characterize its rheological properties. Laboratory experiments which include penetration test, softening point test and viscosity tests were conducted. The results show that by adding 12.5%, 15%, and 20% of OPFASH by weight of asphalt cement, the rheological properties of O-MAC improve significantly compared with its original asphalt cement.
