SBS改性沥青在高速公路路面工程中的应用

Application of the SBS modified asphalt in the pavement engineering of the expressway

结合施工实践,从基质沥青、细骨料、粗骨料及填料等方面对SBS改性沥青混凝土原材料的选取要点作了概述,就改性沥青配合比设计及混合料的温度控制、拌和、运输和碾压作出总结,以完善SBS改性沥青的使用性能。

Combined with the construction practice, the author summarizes the selection points of the SBS modified asphalt concrete raw materials from the aspects of the base asphalt, the fine aggregate, the coarse aggregate and the filler, summarizes the mix design of the modified asphalt, the temperature control, the stirring, the transportation and the rolling of the mixture to perfectthe service performance of SBS modified asphalt.
