The invention relates to the field of road materials, and discloses latex type wheel-sticking-free emulsified asphalt as well as a preparation method and application thereof. The emulsified asphalt comprises the following raw materials in parts by weight: 50-100 parts of matrix asphalt, 15-50 parts of special asphalt, 1-6 parts of a viscosity reducer, 2-16 parts of epoxy resin latex, 0.1-5 parts of an asphalt emulsifier, 0.1-0.5 part of a thickening agent, 0.5-3 parts of an acid-base regulator, 0-0.3 part of an auxiliary agent and 60-100 parts of water. The latex type non-sticking wheel emulsified asphalt provided by the invention has the characteristics of non-sticking wheel, high demulsification speed and high coagulation speed, the PG grading of evaporation residues and the dynamic viscosity at 60 DEG C are obviously improved, and when the latex type non-sticking wheel emulsified asphalt is used as a bonding layer between pavement structure layers, the damage of construction equipment and transport vehicles to a bonding layer material can be avoided, and the service life of the latex type non-sticking wheel emulsified asphalt is prolonged. The preparation method reduces the loss of the bonding layer material and the pollution to the surrounding environment, reduces the damage degree of the bonding layer, improves the durability and the construction efficiency of the pavement, and is simple, high in practicability and suitable for large-scale production.
本发明涉及道路材料领域，公开了一种胶乳型不粘轮乳化沥青及其制备方法与应用，所述乳化沥青包括如下重量份数的原料：基质沥青50‑100份、特种沥青15‑50份、降粘剂1‑6份、环氧树脂胶乳2‑16份、沥青乳化剂0.1‑5份、增稠剂0.1‑0.5份、酸碱调节剂0.5‑3份、助剂0‑0.3份、水60‑100份。本发明提供的胶乳型不粘轮乳化沥青，具有不粘轮、破乳速度快、凝结快的特点，蒸发残留物的PG分级和60℃的动力粘度有明显改善，作为路面结构层之间的粘结层使用时，能够避免施工设备及运输车辆对粘结层材料的破坏，减少粘结层材料的损失和对周边环境的污染，降低粘结层的损伤程度，提高路面的耐久性和施工效率，且制备方法简单、实用性强，适用于大规模生产。
