阳离子乳化沥青是六十年代初在国际上出现的一种新型材料。鉴于它具有与砂粒粘结力强、对水质要求低、乳化剂用量少、耗能低和对植物无毒害等特点,被誉为第三新型工程材料。 本文利用国产的阳离子乳化剂十八烷基三甲基氯化铵(OT),从理论计算和实验分析两个方面,对其用量进行了选择,确定了中裂型OT阳离子乳化沥青配方;研究并推导了乳化温控方程。1981年,利用此配方在沙漠中进行了13000平方米的流沙固定和公路路面铺设试验,证明了它的可靠性。
Cationic emulsified asphalt is a new type of material appearing in the world in early 1960s. In view of its strong adhesion with the sand, low water quality requirements, less emulsifier, low energy consumption and non-toxic to plants and other characteristics, known as the third new type of engineering materials. In this paper, the domestic cationic emulsifier octadecyltrimethylammonium chloride (OT) was used in the calculation and experimental analysis of the two aspects, the amount was selected to determine the cracking of OT cationic emulsified asphalt formulation; study Derived the temperature equation of emulsification. In 1981, 13,000 square meters of quicksand fixed and road pavement tests were carried out using this formula in the desert, demonstrating its reliability.
