环氧沥青水泥砂浆及其制备方法及其在无砟轨道上的应用
摘要：
本发明公开了一种环氧沥青水泥砂浆及其制备方法及其在无砟轨道上的应用，环氧沥青水泥砂浆是由水泥、砂、环氧沥青A、B组分乳液、水、减水剂、消泡剂、铝粉、膨胀剂等拌合而成。水泥、砂、膨胀剂及铝粉等先期混合均匀，制成干料。环氧沥青水泥砂浆各原料组成为：干料：1350-1560重量份；环氧沥青乳液A：0-50重量份；环氧沥青乳液B：230-280重量份；水：135-180重量份；减水剂：0.5-10重量份；消泡剂：0-5重量份。本发明的环氧沥青水泥砂浆服役温度域宽，耐候性优异，耐化学腐蚀性强，使用寿命长，特别适用于客运专线CRTSⅡ型板式无砟轨道中。本发明还包括上述砂浆的制备方法和在无砟轨道中的应用。
摘要（英）：

The present invention discloses an epoxy asphalt cement mortar, a preparation method, and an application of the epoxy asphalt cement mortar in ballastless tracks. The epoxy cement mortar is prepared by mixing cement, sand, an epoxy asphalt emulsion component A, an epoxy asphalt emulsion component B, water, a water reducing agent, an antifoaming agent, aluminum powder, an expansion agent and the like, wherein the cement, the sand, the expansion agent, the aluminum powder and the like are firstly uniformly mixed to prepare the dried material. The raw materials of the epoxy asphalt cement mortar comprise, by weight, 1350-1560 parts of the dried material, 0-50 parts of the epoxy asphalt emulsion A, 230-280 parts of the epoxy asphalt emulsion B, 135-180 parts of the water, 0.5-10 parts of the water reducing agent and 0-5 parts of the antifoaming agent. The epoxy asphalt cement mortar of the present invention has characteristics of wide working temperature range, excellent weather resistance, strong chemical resistance and long service life, and is especially suitable for the passenger special line CRTS TT type slab ballastless tracks. The present invention further provides the preparation method for the epoxy asphalt cement mortar, and the application of the epoxy asphalt cement mortar in the ballastless tracks.
