Asphalt concrete and production process thereof
The invention relates to the technical field of asphalt concrete preparation, and discloses asphalt concrete, which comprises the following components in percentage by mass: 14%-20% of modified asphalt, 5%-13% of cement, 60%-70% of aggregate, 5%-6% of thermosetting plastic and 3%-5% of crushed asbestos cloth. The modified asphalt comprises matrix asphalt and a modifier, and the modifier is an SBSmodifier; the aggregate comprises any one or more of mineral powder, granite, quartzite, basalt and building aggregate; and the thermosetting plastic is selected from diallyl phthalate. According to the invention, the purpose of enhancing the cohesiveness can be achieved, and the crushed asbestos cloth is added into the asphalt concrete, so that the cohesiveness of the asphalt concrete is enhanced, and the asphalt concrete pavement can be more effectively prevented from splitting.
本发明涉及沥青混凝土制备技术领域，公开了一种沥青混凝土，沥青混凝土包括：以质量百分比计，改性沥青14％～20％、水泥5％～13％、集料60％～70％、热固性塑料5％～6％、石棉碎布3％～5％；改性沥青包括基质沥青和改性剂，改性剂选用SBS改性剂；集料包括矿粉、花岗岩、石英岩、玄武岩和建筑骨料的任意一种或多种；热固性塑料选用聚邻苯二甲酸二丙烯酯。本发明可实现增强粘固性目的，在沥青混凝土中添加石棉布的碎布，增强了沥青混凝土的粘粘性，可更为有效防止沥青混凝土路面分裂。
