Modified asphalt composite material, preparation method and application of modified asphalt composite material in ultrathin wearing layer
The invention relates to the technical field of asphalt modification, in particular to a modified asphalt composite material, a preparation method and application of the modified asphalt composite material in an ultrathin wearing layer. Comprising the following raw materials in parts by mass: 4-6 parts of SBS (Styrene Butadiene Styrene), 3-5 parts of LDPE (Low-Density Polyethylene), 3-5 parts of epoxy castor oil, 2-4 parts of octasulfydryl POSS (Polyhedral Oligomeric Silsesquioxane) modified wood fiber, 1-3 parts of an antifreeze agent, 0.1-0.2 part of a mixed catalyst, 6-10 parts of modified asphalt, 5-8 parts of waste tire rubber powder and 100 parts of basalt wear-resistant aggregate. The anti-freezing agent is prepared by mixing AB modified mesoporous copper sulfide, ILs-GO and dialdehyde group PEG (Polyethylene Glycol) according to the mass ratio of (0.7 to 0.9): (0.2 to 0.3): 1; the modified asphalt is prepared by mixing and banburying 10 parts of petroleum asphalt and 0.6-1.2 parts of tetraallylsilane. The modified asphalt composite material prepared by the invention has good frost crack resistance and certain intrinsic self-repairing performance.
本发明涉及沥青改性技术领域，尤其涉及一种改性沥青复合材料、制备方法及其在超薄磨耗层中的应用，包括以下质量份原料：SBS 4‑6份、LDPE 3‑5份、环氧蓖麻油3‑5份、八巯基POSS改性木质纤维2‑4份、抗冻剂1‑3份、混合催化剂0.1‑0.2份、改性沥青6‑10份、废旧轮胎橡胶粉5‑8份、玄武岩耐磨骨料100份；所述抗冻剂由AB改性介孔硫化铜、ILs‑GO、双醛基PEG按(0.7‑0.9):(0.2‑0.3):1的质量比混合而成；所述改性沥青由10份石油沥青和0.6‑1.2份四烯丙基硅烷混合密炼而成。本发明制出的改性沥青复合材料具有良好的抗冻裂性能，并具有一定的本征型自修复性能。
