Summary:This invention relates to compound modified asphalt that utilize discarded packet polymer. According to weight composition: discarded packet polymer EVA 3 to 6%, scrap tire powder 5 to 15% and matrices pitch 79 to 91%. First melt matrices pitch, then add discarded packet polymer EVA and scrap tire powder, whip, standing, another time high speed cut by guillotine after abundantly swelling, till discarded packet polymer EVA and scrap tire powder disperse in pitch uniformity. This invention adopts 'two step' modified craft, reduce cost and advance over-all properties of pitch, remit white pollution problem.
