Graphene modified emulsified asphalt-cement-based composite elastic curing grouting material for railway ballast as well as preparation method and application of graphene modified emulsified asphalt-cement-based composite elastic curing grouting material
The invention discloses a graphene modified emulsified asphalt-cement-based composite elastic curing grouting material for a railway ballast as well as a preparation method and application of the graphene modified emulsified asphalt-cement-based composite elastic curing grouting material. According to the composite elastic curing grouting material for the railway ballast, the rigidity of a cured ballast bed during application can be adjusted by adjusting the CA ratio and blending the components of the elastic latex and the rubber powder, so that the deformation of the upper part and the lower part of a track is coordinated, the pulverization and degradation of the railway ballast are slowed down, and the maintenance workload is reduced. Meanwhile, the composite elastic curing grouting material for the railway ballast can design a special curing ratio according to the service area of a ballast bed so as to reduce the unbalance of a track structure caused by a temperature effect; corresponding curing proportions can be designed for different load-carrying trains according to line operation conditions so as to meet the requirements of ballast bed supporting rigidity and longitudinal and transverse resistance. The composite elastic curing grouting material for the railway ballast can be applied to existing line transformation granular ballast curing and prefabricated elastic curing ballast beds, the preparation raw materials are wide in source, energy-saving and environment-friendly design can be carried out, and benefits are good.
本发明公开了一种石墨烯改性乳化沥青‑水泥基复合道砟弹性固化灌浆材料及其制备方法和应用。该复合道砟弹性固化灌浆材料通过调整其中CA配比及掺合弹性胶乳和橡胶粉组分，可达到调节应用时固化后道床的刚度，从而协调轨道上下部分的变形，减缓道砟粉化劣化，减小维护工作量。同时，该复合道砟弹性固化灌浆材料可根据道床服役地区，设计专用固化配比，以降低温度效应带来的轨道结构失衡；还可根据线路营运条件，针对不同载重列车设计相应固化配比，以满足道床支承刚度及纵、横向阻力要求。本发明的复合道砟弹性固化灌浆材料可应用在既有线改造散粒体道砟固化和预制装配式弹性固化道床中，其制备原料来源广泛，可进行节能环保设计，效益良好。
