High-strength anti-cracking modified asphalt additive for cement pavement and preparation method of high-strength anti-cracking modified asphalt additive
The invention discloses a high-strength anti-cracking modified asphalt additive for a cement pavement and a preparation method of the high-strength anti-cracking modified asphalt additive. The high-strength anti-cracking modified asphalt additive comprises butadiene-styrene rubber, a linear triblock copolymer, rubber oil, an ethylene-vinyl acetate copolymer, tackifying petroleum resin and an antioxidant. During preparation, the butadiene-styrene rubber, the linear triblock copolymer, the rubber oil, the ethylene-vinyl acetate copolymer, the tackifying petroleum resin and the antioxidant are mixed and then extruded and granulated by a twin-screw extruder to prepare the adhesive. The low-temperature small beam bending strain of a mixture prepared from the additive is larger than 7000 mu epsilon, the fatigue life of the mixture at the temperature of 15 DEG C and the temperature of 1000 mu epsilon is larger than 200 thousand times, the APA anti-reflection capacity is larger than 500 thousand times, and the anti-cracking performance is excellent.
本发明公开了一种用于水泥路面的高强抗裂改性沥青添加剂及其制备方法，包括丁苯胶，线性三嵌共聚物，橡胶油，乙烯‑乙酸乙烯共聚物、增粘石油树脂，抗氧剂；制备时将丁苯胶，线性三嵌共聚物，橡胶油，乙烯‑乙酸乙烯共聚物、增粘石油树脂及抗氧剂混合后，经过双螺杆挤出机挤出造粒后制成。采用本发明的添加剂制备的混合料低温小梁弯曲应变＞7000με，15℃，1000με的疲劳寿命＞20万次，APA防反射能力＞50万次，抗裂性能优异。
