Method for processing pavement mixture from unqualified ground tire rubber asphalt

Abstract

本发明提供一种用不合格废胎胶粉橡胶沥青加工路面混合料的方法,该方法包括先测量不合格废胎胶粉橡胶沥青180℃旋转粘度:再确定新掺废胎胶粉的用量:然后拌和废胎胶粉与集料:再拌和废胎胶粉橡胶沥青混合料:然后焖料:最后摊铺、碾压便做成废胎胶粉橡胶沥青混凝土路面。本发明使180℃旋转粘度下降到小于2Pa·s的不合格废胎胶粉橡胶沥青不需要经过再加工就可以直接使用,并且采用本方法加工的废胎胶粉橡胶沥青混合料的路用性能满足规范要求;该方法简单,实用快捷,容易掌握,施工方便,避免浪费,提高了工作效率。
The invention provides a method for processing a pavement mixture from unqualified ground tire rubber asphalt. The method comprises the following steps: measuring the 180-DEG C rotary viscosity of the unqualified ground tire rubber asphalt; determining the amount of the newly doped ground tire; mixing the ground tire with aggregate; mixing with the ground tire rubber asphalt mixture; stewing; and finally, spreading and rolling to obtain the ground tire rubber asphalt concrete pavement. The unqualified ground tire rubber asphalt of which the 180-DEG C rotary viscosity is lowered to less than 2 Pa.s can be directly used without reprocessing, and the pavement performance of the ground tire rubber asphalt mixture processed by the method satisfies the specified requirements. The method is simple, practical and quick, is easy to master and convenient for construction, avoids the waste, and enhances the work efficiency.
