▎ 摘  要

NOVELTY - A wave-absorbing asphalt concrete comprises 3.5-5 %mass modified asphalt, 40-62 %mass stone coarse aggregate, 15-25 %mass stone fine aggregate, 15-25 %mass magnetite slag or copper slag broken fine aggregate, 1-2 %mass cement, and 3-6 %mass graphene and ferroferric oxide mixed grinding absorbing powder. USE - Wave-absorbing asphalt concrete for deicing and snowing. ADVANTAGE - The wave-absorbing asphalt concrete covers on pavement wear layer which increases the wave absorbing and heating rate of the pavement surface layer and greatly improves the working efficiency of the microwave deicing and snow removal method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the wave-absorbing asphalt.
