Environment-friendly special emulsified asphalt for dust suppression of road surface, and preparation method and construction method of environment-friendly special emulsified asphalt
The invention discloses environment-friendly special emulsified asphalt for dust suppression of a road surface, and a preparation method and a construction method of the environment-friendly special emulsified asphalt. The environment-friendly special emulsified asphalt is prepared from the following raw materials: common asphalt, an asphalt additive, an emulsifier, water and a pH regulator. The preparation method comprises the following steps: 1) heating the common asphalt to 120-150 DEG C, adding the asphalt additive into the common asphalt in proportion, and carrying out uniform stirring toobtain a mixture of the asphalt and the asphalt additive; 2) adding water into the emulsifier accounting for 1-20% of the total mass of the emulsified asphalt to prepare emulsifier soap liquid, adding the pH regulator to regulate the pH value of the emulsifier soap liquid to 10-14, and heating the emulsifier soap liquid to 35-60 DEG C; and 3) sequentially grinding the emulsifier soap liquid and amixture of the asphalt and the asphalt additive through a colloid mill to obtain a finished emulsified asphalt product. The construction method comprises the following steps: (1) pretreatment beforeapplying a dust suppressant; and (2) spraying of the finished emulsified asphalt product to enable the finished emulsified asphalt product to penetrate into the road surface. A hard shell is established on the surface layer of the road surface by utilizing the finished emulsified asphalt product so as to control dust.
本发明公开了专用于路面抑尘的环保型乳化沥青、制备方法及施工方法，其中环保型乳化沥青通过普通沥青、沥青添加剂、乳化剂、水和pH调节剂为原料制得，制备方法包括以下步骤：1)将普通沥青加热至120‑150℃，将沥青添加剂按比例加入普通沥青中搅拌均匀得到沥青与沥青添加剂的混合物；2)乳化剂按乳化沥青总质量的1‑20％加水配制成乳化剂皂液，加入pH调节剂将乳化剂皂液pH值调为10‑14，然后加热至35‑60℃；3)将上述乳化剂皂液及沥青与沥青添加剂的混合物依次通过胶体磨，研磨后得到乳化沥青成品；施工方法，包括以下步骤：1)应用抑尘剂前的预处理2)喷洒乳化沥青成品，使乳化沥青成品穿透到路面里面，利用乳化沥青成品在路面表层建立硬壳，控制尘土。
