摘要
目前,我国的高速路网已经很完善,许多高速公路也已进入维修养护期,沥青路面的养护技术也越来越受到重视。微表处技术自引入国内以来以节能环保、施工方便、造价低、开放交通快、使用寿命长等优势而得到广泛推广。影响微表处混合料的因素有很多,就添加剂水泥这一因素进行了具体的室内试验,并从可拌和时间、粘聚力指标、湿轮磨耗值和低温抗裂性分析总结了水泥对微表处乳化沥青混合料路用性能的影响规律,并对微表处施工工艺提供指导依据。
At present, the expressway network has been more perfected in China. Many expressways have also come into the maintenance period. More and more attention is also paid to the maintenance technology of asphalt pavement. The micro surface technology is widely popularized since introduced into China because of its advantages of energy conservation, environmental protection, convenient construction, low construction cost, fast traffic opening and long service life. There are many factors influencing the mixture of micro surface.A factor of additive cement is experimented in laboratory. The article analyzes and summarizes the influence law of cement on the pavement performance of emulsified asphalt mixture of micro surface from the aspects of mixable time, cohesion index, wet wheel wear value and low-temperature crack resistance, and provides the guidance basis for the construction technology of micro surface.
