Rubber powder epoxy asphalt cementing material for expansion joints, prefabricated structure, preparation method and application of rubber powder epoxy asphalt cementing material
The invention provides a rubber powder epoxy asphalt cementing material for expansion joints, a prefabricated structure and a preparation method and application thereof, and the material is prepared from the following components in parts by mass: 9-11 parts of matrix asphalt, 2-5 parts of epoxy resin, 2-5 parts of curing component, 3-7 parts of rubber powder and 68-85 parts of mineral aggregate. The rubber powder, the epoxy resin and the epoxy resin curing agent are introduced into the matrix asphalt, so that the thermoplasticity of the asphalt can be changed, and the seamless expansion joint has excellent high and low temperature performance. The concrete is used for preparing a prefabricated seamless expansion joint structure, pavement construction is carried out, an expansion body component is prefabricated and produced in a prefabrication field, installation and construction are carried out on site, large equipment is not needed, maintenance and transportation are convenient, the construction time is short, and the construction cost is low. And meanwhile, the defects of long on-site paving and curing time and long traffic closing time of the epoxy asphalt mixture can be avoided.
本发明提供一种伸缩缝用胶粉环氧沥青胶结料及预制结构、其制备方法及应用，该材料，其按质量份数计，包括，基质沥青9~11份、环氧树脂2~5份、固化组分2~5份、胶粉3~7份、矿质集料68~85份。在基质沥青中引入胶粉以及环氧树脂与环氧树脂固化剂，能够改变了沥青的热塑性，使无缝伸缩缝具备优异的高低温性能。用该结料制备预制式无缝伸缩缝结构，并进行路面施工，将伸缩体构件在预制场预制生产，在现场进行安装施工，无需大型设备，维修运输便捷，施工时间短、施工成本低。同时，可以避免环氧沥青混合料现场摊铺养生时间长，封闭交通时间长的缺点。
