Application of Modified Medium Temperature Asphalt in Highway Pavement Construction

为研究改性中温沥青在高速公路路面施工中的应用,依托实际施工工程,研究了改性中温沥青混合料的施工工艺、技术要点,通过室内试验对改性中温沥青混合料的原材料进行物理性能检测。研究了表面活性剂对改性中温沥青混合料高温稳定性的影响,并对竣工后的路面进行平整度检测。结果表明,以改性中温沥青混合料进行路面施工,可以满足路面的平整度、高温性能,可用于高速公路路面施工。

In order to study the application of modified medium temperature asphalt in highway pavement construction, the construction process and technical key points of modified medium temperature asphalt mixture were studied based on the actual construction project. The physical properties of the raw materials of modified medium temperature asphalt mixture were tested through indoor test. The influence of surfactants on the high temperature stability of modified medium temperature asphalt mixture was studied, and the pavement smoothness after completion was tested. The results show that the modified medium temperature asphalt mixture can meet the pavement smoothness and high temperature performance, and can be used for highway pavement construction.
