Special high-performance modified asphalt for ultrathin wearing layer and preparation method thereof
The invention belongs to the technical field of modified asphalt, and particularly relates to special high-performance modified asphalt for an ultrathin wearing layer and a preparation method thereof.According to a scheme in the invention, the modified asphalt comprises the following component materials in parts by mass: 30 to 45 parts of asphalt, 15 to 20 parts of rubber, 1 to 10 parts of a modifier, 1 to 5 parts of a stabilizer, 0.3 to 0.6 part of fibers, 15 to 20 parts of coarse aggregate, 10 to 25 parts of fine aggregate, 15 to 20 parts of a filler and 0.05 to 0.1 part of an anti-aging agent. According to the special high-performance modified asphalt for the ultrathin wearing layer, ultrathin pavements are respectively formed by adopting raw materials of different gradation and proportions, so the pavements have good freeze-thaw resistance, stability, durability and self-adhesion and can effectively resist high temperature and abrasion of ruts; and the special high-performance modified asphalt can be applied to reconstruction and maintenance of newly-built pavements and old pavements.
本发明属于改性沥青技术领域，尤其是超薄磨耗层专用高性能改性沥青及其制备方法，现提出以下方案，包括以下质量比的组分材料，沥青30‑45份、橡胶15‑20份、改性剂1‑10份、稳定剂1‑5份、纤维0.3‑0.6份、粗集料15‑20份、细集料10‑25份、填料15‑20份、防老化剂0.05‑0.1份。发明的超薄磨耗层专用高性能改性沥青采用不同级配的原料和配比分别形成的超薄路面，能够使得路面具有良好的抗冻融性、稳定性、耐久性，具有良好的自粘性，有效的对抗车辙高温和磨耗，可在新建路面和旧路面改造维护方面应用。
