一种改性乳化沥青及其制备方法
摘要：
本发明公开了一种改性乳化沥青及其制备方法，该改性乳化沥青按重量百分比计包括：沥青55%～65%，阳离子乳化剂0.3%～1.5%，阴离子乳化剂0.3%～1.5%，稳定剂0.05%～0.15%，增稠剂0.01%～0.05%，减水剂0.1%～0.5%，醇0.8%～3.5%，聚合物胶乳1%～4%，水？30%～35%。本发明改性乳化沥青与水泥混合性好、储存稳定性好、筛上剩余量少，同时具有抗冻性、无泌水、柔韧性和粘结性好等优点。本发明改性乳化沥青特别适合用于修筑高速铁路时，制备板式无砟轨道的灌注水泥沥青砂浆。
摘要（英）：

The invention discloses modified emulsified asphalt and a preparation method thereof. The modified emulsified asphalt comprises the following components by weight: 55%-65% of asphalt, 0.3%-1.5% of cationic emulsifiers, 0.3%-1.5% of anionic emulsifiers, 0.05%-0.15% of stabilizing agents, 0.01%-0.05% of thickening agents, 0.1%-0.5% of water reducers, 0.8%-3.5% of alcohol, 1%-4% of polymer latex, and 30%-35% of water. The modified emulsified asphalt of the invention is good in miscibility with cement, good in storage stability, and low in oversize residual amount, and also has the advantages of freezing resistance, no bleeding, good flexibility, and good caking property. The modified emulsified asphalt of the invention is especially applicable to cement injection asphalt mortar for preparing plate-type ballastless tracks in high speed railway building.
