Production process of environment-friendly modified asphalt
The invention discloses an environment-friendly modified asphalt production process which sequentially comprises the following steps: (1) heating matrix asphalt to 180-190 DEG C, and keeping the temperature for 2-3 minutes; (2) shearing the matrix asphalt through a first shearing emulsifying machine; (3) introducing the asphalt mixture into a first development tank, carrying out first development, adding an SBS modifier, carrying out heat preservation when the asphalt mixture is cooled to 160-170 DEG C, and meanwhile, continuously stirring for 13-15 hours; (4) shearing the asphalt mixture through a second shearing emulsifying machine; according to the present invention, the process is simple, the number of the working procedures is small, the produced modified asphalt efficiently uses the waste tire, the waste tire is reused, the environmental protection property is provided, the added SBS and the waste tire abrasive material make the produced modified asphalt not easy to soften at a high temperature and not easy to embrittle at a low temperature, and the problems of rutting, cracking, temperature shrinkage and the like are significantly reduced; in addition, the low-temperature fluidity and the ductility of the asphalt can be improved, and the asphalt has relatively good elastic deformation capability.
本发明公开了环保型改性沥青生产工艺，包括以下依序进行的步骤：①将基质沥青加热到180℃～190℃，保温2min～3min；②将基质沥青通过第一剪切乳化机剪切；③将沥青混合物通入第一发育罐进行第一次发育，加入SBS改性剂，待沥青混合物降温至160℃～170℃时保温，同时持续搅拌13h～15h；④将沥青混合物通过第二剪切乳化机剪切；本发明工艺简单，工序少，生产的改性沥青不仅高效利用了废旧轮胎，使其再利用，具有环保属性，添加SBS和废旧轮胎研磨物，生产的改性沥青高温不易软化低温不易发脆，显著减少车辙、开裂、温缩等问题；并且能够提高沥青的低温流动性和延展度，并且使其具有较好的弹性变形能力。
