摘要: 以CA砂浆用阴离子乳化沥青贮存稳定性为依据,研究了乳化设备、乳化剂、助剂、沥青含量等对乳化沥青贮存稳定性的影响。结果表明:不同的乳化设备,乳化剂的用量,助剂的种类及用量,沥青的含量等均对乳液稳定性有着较大的影响;在乳化剂的用量为3.5%,缔合型增稠剂T的用量为0.4%,羧甲基纤维素钠的用量为0.06%,沥青含量为60%时,使用美国DALWORTH道维施型实验室改性沥青/乳化沥青组产设备生产的乳化沥青及其使用该乳化沥青制备的CA砂浆的性能均能满足铁道部《客运专线CRTSⅡ板式无砟轨道水泥乳化沥青砂浆暂行技术条件》的要求。

Abstract: The effects of specific factors (including equipment, emulsifier, additives and asphalt content) on the stability of emulsified asphalt for cement and asphalt (CA) mortar were studied. Results showed that the emulsifying equipment, the amount of emulsifier, the type and amount of additives and asphalt content had great influences on the stability of emulsion, the optimum preparation conditions of emulsified asphalt were using SD-2 emulsifier with a dosage of 3.5%, an association thickening agent T of 0.4 %, a cellulose sodium (CMC) of 0.06 %, an asphalt mass fraction of 60% and applying colloid mill. The qualities of emulsified asphalt obtained under such conditions and CA mortar prepared by said emulsion could well meet the requirements of relative specifications issued by Ministry of Railways.
