Polyurethane modified asphalt concrete
The invention discloses polyurethane modified asphalt concrete, which is characterized by being prepared from the following components in parts by mass: 100 to 150 parts of aggregate, 20 to 40 parts of epoxy modified asphalt, 5 to 8 parts of polyurethane prepolymer, 1 to 2 parts of wood diversified alcohol, 3 to 5 parts of temperature adaptation agent, 2 to 4 parts of hardening agent, 2 to 3 parts of anti-stripping agent, 1 to 3 parts of antioxidant and 1 to 3 parts of modified rubber powder, the aggregate comprises fine aggregate, coarse aggregate, silicon powder and fly ash in a mass ratio of 1: (2-4): (0.2-0.6): (0.1-0.2). The polyurethane prepolymer is modified by the wood diversified alcohol, so that the dispersity of polyurethane in an asphalt concrete system is improved, the stability of the system is improved, and the high-temperature performance of the polyurethane modified asphalt concrete is improved. The asphalt concrete has the effects of improving the high-temperature and low-temperature performance, ultraviolet resistance, oxidation resistance and antibacterial performance of the asphalt concrete.
本发明公开了一种聚氨酯改性沥青混凝土，其特征在于：包括以下质量份数的组分：集料100‑150份、环氧改性沥青20‑40份、聚氨酯预聚体5‑8份、木质多元化醇1‑2份、温度适应剂3‑5份、硬化剂2‑4份、抗剥落剂2‑3份、抗氧化剂1‑3份和改性胶粉1‑3份，所述集料包括质量比为：1:(2‑4):(0.2‑0.6):(0.1‑0.2)的细骨料、粗骨料、硅粉和粉煤灰。聚氨酯预聚体经过木质多元化醇的改性处理，改善了聚氨酯在沥青混凝土体系中的分散性，提升了体系的稳定性，从而提升聚氨酯改性沥青混凝土的高温性能。该种沥青混凝土具有提升沥青混凝土高温和低温性能、抗紫外线、抗氧化和抑菌性能的效果。
