Polyurethane emery steel bridge deck pavement material and pavement method thereof
The invention discloses a polyurethane emery steel bridge deck pavement material and a pavement method thereof, and belongs to the field of bridge deck pavement. The invention aims to solve the problem that the mechanical property and the road property of the current bridge deck pavement material are quickly attenuated. The invention mainly comprises a two-component polyurethane binder and a carborundum aggregate, wherein the mass ratio of the two-component polyurethane binder to the carborundum aggregate is 1: (4-6) when the two-component polyurethane binder and the carborundum aggregate are used; the bi-component polyurethane adhesive is composed of polymethyl polyphenyl isocyanate and polyether which are independently packaged, and the bi-component polyurethane adhesive is uniformly mixed according to the mass ratio of 1: 1 when in use. According to the method, the stress and deformation of the steel bridge deck structure can be effectively reduced, and the stress and interlayer cohesiveness can be improved in a light composite bridge deck pavement simulation scheme.
本发明公开了一种聚氨酯金刚砂钢桥面铺装材料及其铺装方法，属于桥面铺装领域。本发明要解决目前桥面铺装材料的力学性能和道路性能衰减迅速的问题。本发明其主要是由双组分聚氨酯粘结剂和金刚砂骨料组成，使用时双组分聚氨酯粘结剂和金刚砂骨料的质量比为1:(4‑6)；双组分聚氨酯粘结剂是由单独包装的聚甲基聚苯基异氰酸酯和聚醚组成，双组分聚氨酯粘结剂使用时按1:1的质量比混合均匀。本发明可以有效降低钢桥面结构的应力和变形，提高应力和层间粘结性在模拟轻型复合桥面铺装方案中。
