High-bondability recycled asphalt concrete and preparation process thereof
The patent of the present invention relates to the technical field of preparation of recycled asphalt concrete, and aims to provide high-bondability recycled asphalt concrete and a preparation processthereof. The recycled asphalt concrete and the process are characterized in that the recycled asphalt concrete comprises, by weight, 73-88 parts of mixed aggregate, 3-7 parts of SBS modified asphalt,0.5-0.9 part of coal ash, 22-26 parts of recycled asphalt mixed old materials, 0.15-0.25 part of a regenerating agent, 0.1-0.15 part of a defoamer, 5-13 parts of steel slag, 5-9 parts of reinforcingfibers, 5-10 parts of a filler, 5-9 parts of fluororubber powder and 5-8 parts of graphene. The recycled asphalt concrete has high bondability with old concrete during paving processes, good in adhesive force and not liable to generate cracks.
本发明专利涉及再生沥青混凝土制备技术领域，旨在提供一种高结合性再生沥青混凝土及其制备工艺，其技术方案要点是，包括以下重量份的组分：混合集料73～88份、SBS改性沥青3～7份、粉煤灰0.5～0.9份、再生沥青混合旧料22～26份、再生剂0.15～0.25份、消泡剂0.1～0.15份、钢渣5～13份、增强纤维5～9份、填充料5～10份、氟橡胶粉5～9份、石墨烯5～8份。本发明具有在铺路时与旧混凝土之间结合性能强、粘结性好、不易产生裂缝的优点。
