Study on improving the properties of natural asphalt using cork wastes

Abstract

This research is simply deal with two principles locally and internationally first is about environmental pollution which is the global problem and second about the economic as result of recycling and no need for costly materials and from the important pollutants we face is corks wastes.in this research cork was melted by benzene and used as filler to the natural Heet asphalt to get good paste with a weight percentage (cork paste-filler- g per 100 g of Heet asphalt) the percentage are 0%, 10%, 20%, then the asphalt properties was studied after and before adding filler and 29 g/100 g of aspects is the optimum percent that make the asphalt meet the international specifications (ASTM D312) and Iraqi specifications (88-1196) as a proofing material.
