High-strength recycled asphalt mixture and preparation process thereof
The invention discloses a high-strength recycled asphalt mixture and a preparation process thereof. The mixture comprises the following components: 20%-30% of new asphalt, 30%-50% of new aggregate, 30%-40% of recycled asphalt concrete, 10%-15% of recycled rubber and 3%-5% of a regenerant. The regenerant comprises 60%-70% of matrix oil, 30%-40% of a plasticizer and 5%-10% of an anti-aging agent; the anti-aging agent comprises an antioxidant and an ultraviolet light absorber; the ratio of the two is 4: 3; the process is simple, and the prepared regenerant is fused, so that the aged asphalt can be repaired to a certain extent, and the plastic deformation capability of the asphalt can be improved; the oxidation resistance and ultraviolet aging resistance of the mixture can be improved, and the service life of the mixture is prolonged; the recycled rubber is added, so that the viscosity of the mixture can be increased, the overall structural strength can be enhanced, and the stability of the overall structure can be improved.
本发明公开了高强度再生沥青混合料及制备工艺，该混合料成分包括20％～30％新沥青、30％～50％新集料、30％～40％回收沥青混凝土、10％～15％回收橡胶以及3％～5％再生剂；所述再生剂包括60％～70％基质油、30％～40％增塑剂以及5％～10％抗老化剂；所述抗老化剂包括抗氧化剂和紫外线吸收剂；两者配比为4:3；该工艺简单，融合了配置的再生剂，不仅在一定程度上有助于修复老化沥青，而且能够改善沥青的塑形变形能力；还能提高混合料的抗氧化性和抗紫外线老化能力，延长其使用寿命；添加了回收橡胶，不仅能够增加混合料的粘度，而且能够加强整体的结构强度，提高整体结构的稳定性。
