Polyurethane cementing material for airport pavement, and polyurethane concrete for repairing
The invention provides a polyurethane cementing material for an airport pavement, and a polyurethane concrete for repairing. The polyurethane cementing material is composed of polyether polyol, isocyanate and an auxiliary agent, and a normal-temperature mixing mode is adopted as a production mode; and the polyurethane concrete is formed by combining a polyurethane binder and aggregate, and a cold mixing and cold paving construction mode is adopted, so that the polyurethane concrete is energy-saving, environment-friendly and good in environmental benefit. The polyurethane concrete disclosed by the invention is excellent in performance and has obvious advantages in the aspects of strength, wear resistance, durability, compound performance and the like, and the performance of an airport pavement is improved; the bonding performance of the polyurethane concrete and the airport cement concrete pavement is excellent, so that the service life of the pavement can be effectively prolonged, and the later maintenance cost is reduced; and the curing time of the polyurethane concrete is short, the airport pavement can be repaired in a very short time, the traffic can be opened, the airport stop loss is reduced, and the polyurethane concrete has good economic and social benefits.
本发明提出一种机场道面用聚氨酯胶结料及修补用聚氨酯混凝土。所述聚氨酯胶结料由聚醚多元醇、异氰酸酯和助剂组成，生产方式采用常温拌和方式；所述聚氨酯混凝土由聚氨酯粘结剂和集料结合而成，采用冷拌冷铺的施工方式，节能环保，环境效益好。本发明中的聚氨酯混凝土性能优异，强度、耐磨性、耐久性以及复合性能等方面具有明显的优势，提高机场道面性能；聚氨酯混凝土与机场水泥混凝土道面的粘结性能极佳，可有效延长道面使用寿命，减少后期养护维修费用；聚氨酯混凝土固化时间短，能在很短时间内修复好机场道面并开放交通，减少停航损失，具有良好的经济和社会效益。
