Ultrathin overlay mixture for preventive maintenance of asphalt pavement, preparation method and additive
The invention discloses an ultrathin overlay mixture for preventive maintenance of an asphalt pavement, a preparation method and an additive. The mixture comprises the following components: 80-90% of aggregate, 5-15% of mineral powder, 4-4.8% of asphalt and 0.15-0.6% of an ultrathin overlay additive for preventive maintenance of asphalt pavement, wherein the ultrathin overlay additive for preventive maintenance of the asphalt pavement comprises the following components: 40-50% of a thermoplastic elastomer, 35-45% of 4006 industrial white oil, 1-10% of polyethylene wax and 5-15% of C5 petroleum resin. According to the present invention, the formula of the ultrathin overlay additive is reasonable, the anti-scattering ability and the water damage resistance of the ultrathin overlay additive can be improved, the flexibility of the surface layer concrete can be improved, and the good anti-fatigue and anti-cracking ability can be provided; and the additive is produced by directly putting the additive into a mixing station, special equipment is not needed, the process is simple, and wide popularization and application are facilitated.
本发明公开了一种沥青路面预防性养护超薄罩面混合料及制备方法和添加剂，混合料的组分为：集料80～90％，矿粉5～15％，沥青4～4.8％，沥青路面预防性养护超薄罩面添加剂0.15～0.6％；沥青路面预防性养护超薄罩面添加剂的组分为：热塑性弹性体40～50％，4006工业白油35～45％，聚乙烯蜡1～10％，C5石油树脂5～15％；本发明提供沥青路面预防性养护超薄罩面添加剂的配方合理，能够提升沥青路面预防性养护超薄罩面混合料的抗飞散能力和抗水损能力，同时改善面层混凝土柔韧性，具有良好的抗疲劳抗开裂能力，同时该添加剂采用直接投入拌合站的方式进行生产，无需专用设备，工艺简单，利于广泛推广应用。
