排水性沥青稳定碎石配合比设计及性能研究

Mixing Ratio Design and Property Study of Drainage Asphalt Stabilized Macadam

通过对我国排水基层级配使用情况的调查,结合我国沥青路面施工规范中推荐的排水性沥青稳定碎石级配范围,进行了排水性沥青稳定碎石配合比设计。并在此设计级配基础上,系统研究了分别使用普通沥青和SBS改性沥青时混合料的高温性能、水稳定性以及渗透性等路用性能,为排水性沥青稳定碎石在我国的应用提供了一定的技术支持和参考依据。

According to the survey of the drainage base gradation and combined with the drainage asphalt stabilized macadam gradation range recommended in the asphalt pavement construction standard in China,the article introduces the mixing ratio design of drainage asphalt stabilized macadam.On the basis of design gradation,the article systematically studies the high-temperature properties,water stabilities and penetrability of the mixture separately added with the ordinary asphalt and SBS modified asphalt,which can be referred and provide some technical support for the application of drainage asphalt stabilized macadam in China.
