Emulsified asphalt for waterproof bonding layer of concrete bridge deck pavement, preparation method of emulsified asphalt and bridge deck pavement structure
The invention relates to the field of road materials, and particularly discloses emulsified asphalt for a concrete bridge deck pavement waterproof bonding layer, a preparation method of the emulsified asphalt and a bridge deck pavement structure. The emulsified asphalt is prepared from raw materials including a water-based emulsion, an acrylate monomer, a photoinitiator and anionic emulsified asphalt; the water-based emulsion is prepared by forming a prepolymer from acrylic acid, methacrylic acid and long-chain fatty amine containing carbon-carbon double bonds, then connecting isocyanate and then closing an NCO group, and the carbon chain length of the long-chain fatty amine containing carbon-carbon double bonds is greater than or equal to 10. The pavement structure comprises a waterproof bonding layer and an asphalt concrete pavement layer, the asphalt concrete pavement layer is prepared from raw materials including matrix asphalt, thermoplastic resin, multi-chain polyolefin and specifically graded aggregate; the specific graded aggregate is stone pretreated by an amino silane coupling agent. The waterproof bonding layer and the pavement structure have good mechanical properties and bonding strength, and the influence on the environment in the construction process is small.
本申请涉及道路材料领域，具体公开了一种混凝土桥面铺装防水粘结层用乳化沥青及其制备方法以及桥面铺装结构，乳化沥青原料由包含水性乳液、丙烯酸酯单体、光引发剂、阴离子乳化沥青的原料制成；水性乳液是由丙烯酸、甲基丙烯酸和含碳碳双键的长链脂肪胺形成预聚体后、连接异氰酸酯、再封闭NCO基团制成，含碳碳双键的长链脂肪胺碳链长度≥10。路面结构包括防水粘结层和沥青混凝土铺装层；沥青混凝土铺装层由包括基质沥青、热塑性树脂、多链聚烯烃和特定级配集料的原料制成；特定级配集料是经过氨基硅烷偶联剂预处理过的石料。本申请的防水粘结层和路面结构具有良好的力学性能和粘结强度，而且施工过程中对环境的影响较小。
