1、提高沥青路面水稳定性为提高高速公路沥青路面水稳定性,可采取以下措施:A集料与沥青的粘附等级应达到5级,允许沥青膜有移动,但是不能有裸露的石料;B必须对沥青混合料进行水稳定性检验,要求残留稳定度不小于85%,冻融劈裂残留强度比不小于80%;C如果集料抗剥离能力不足,可渗入一定剂量的抗剥离剂或石灰,以提高沥青与集料的粘附能力;D可采用该性沥青,以提高胶结料的粘附能力。控制集料含泥量和细集料含量
1, to improve the water stability of asphalt pavement To improve the highway asphalt pavement water stability, the following measures can be taken: A aggregate and asphalt adhesion level should reach 5, allowing the asphalt film to move, but can not have exposed stone; B water stability test must be asphalt mixture required residual stability of not less than 85%, freeze-thaw splitting residual strength ratio of not less than 80%; C if the aggregate anti-stripping ability, can penetrate a certain dose of anti-stripping agent Or lime, to improve the adhesion of asphalt and aggregates; D can be used to improve the adhesion of cementing materials. Control the aggregate content and fine aggregate content
