Polyurethane modified asphalt concrete
The invention relates to polyurethane modified asphalt concrete, which is prepared from the following ingredients in parts by mass: 3 to 5 parts of lignin-based polyurethane prepolymers, 40 to 50 parts of modified asphalt, 800 to 1000 parts of aggregate, 0.5 to 1 part of slow adhesion agents, 1 to 2 parts of coupling agents and 3 to 4 parts of foaming agents, and the modified asphalt comprises matrix asphalt and high-temperature modifiers. 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.
本申请涉及一种聚氨酯改性沥青混凝土，其包括以下质量份数的组分：木质素基聚氨酯预聚体3‑5份，改性沥青40‑50份，集料800‑1000份，缓黏剂0.5‑1份，偶联剂1‑2份，发泡剂3‑4份，所述改性沥青包括基质沥青和高温改性剂。本申请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。
