为解决改性沥青混合料施工时沥青烟气过大的问题,采用温拌沥青混合料技术是一条有效途径。结合温拌沥青混合料在庐山西海高速公路路面下面层的应用,通过室内混合料设计及性能检验,基于表面活性剂的温拌沥青混合料在有效降低混合料温度的同时仍然保持了良好的性能,可满足现行规范要求并可达到相应热拌沥青混合料的性能。在摊铺温拌沥青混合料时,可发现排放出的沥青烟大大减少;工后检测表明,温拌沥青混合料路面质量可满足规范要求。
In order to solve the problem of excessive asphalt flue gas during the construction of modified asphalt mixture, it is an effective way to adopt warm mixed asphalt mixture technology. Based on the application of warm mix asphalt mixture in the lower course of West Lushan Expressway, through the design of mixture in the room and the performance test, the warm mix asphalt mixture based on surfactant can effectively reduce the temperature of the mixture while still maintaining the good performance , To meet the current norms and requirements and can reach the performance of the corresponding hot mix asphalt. When paving warm mix asphalt, it can be found that the discharged bituminous smoke is greatly reduced. After-sales testing shows that the warm mix asphalt mixture pavement quality can meet the specification requirements.
