Polyurethane modified asphalt as well as pavement structure and construction method thereof
The invention relates to the technical field of pavement engineering modification, in particular to polyurethane modified asphalt as well as a pavement structure and a construction method thereof, and is technically characterized in that the polyurethane modified asphalt comprises the following components: SBS (styrene-butadiene-styrene) modified asphalt, rubber powder, heterocyclic modified polyether polyol, polyphenylmethane polyisocyanate, a diamine chain extension cross-linking agent and an activating agent. By means of the pavement structure, the problems that heavy-load rubber cement floats upwards at the high temperature in summer and the anti-skid performance is attenuated are effectively solved, the structure has excellent noise reduction performance and anti-skid performance, comprehensive noise reduction can be conducted through the whole structure, and in addition, the pavement structure is excellent in rutting resistance, high in bearing capacity, capable of resisting reflection cracks, small in structural layer thickness, low in construction temperature and suitable for large-scale popularization and application. Stone materials are saved, and meanwhile construction energy consumption and emission are reduced.
本发明涉及路面工程改造技术领域，具体涉及一种聚氨酯改性沥青及其铺装结构和施工方法，其技术要点如下：聚氨酯改性沥青包括如下组分：SBS改性沥青、橡胶粉、杂环改性聚醚多元醇、多苯基甲烷多异氰酸酯、二胺类扩链交联剂和活化剂。通过本发明，有效解决了统沥青路面夏季高温重载胶浆上浮，抗滑性能衰减的问题，且该结构具有优异的降噪性能和抗滑性能，可利用整个结构进行综合降噪，另外该路面结构抗车辙性能优、承载能力强、抗反射裂缝、结构层厚度小、施工温度低，在节约了石料资料同时降低了施工能耗与排放。
