湿法和干法SBS改性沥青混合料对比研究

Process and Performance Comparison of SBS Modified Asphalt Mixture Produced by Wet and Dry Processes

为了比较湿法和干法两种工艺生产的SBS改性沥青混合料的性能,在分析SBS改性机理基础上,对两种工艺生产的SBS改性沥青混合料路用性能进行了试验研究。结果显示,与湿法工艺相比,干法工艺除了具有生产工艺简单、配方更改方便、节能效果明显等特点之外,干法工艺生产的SBS改性沥青混合料在高温稳定性和水稳定性方面更优越。

In order to compare the properties of SBS modified asphalt mixtures produced by wet and dry processes,the road performance of SBS modified asphalt mixture produced by two kinds of processes is compared and tested on the basis of analyzing the modification mechanism of SBS modifier.The results showed that the road performance of SBS modified asphalt mixture produced by dry process is more excellent in high temperature stability and water stability than wet process in addition to simple production process,easy to change the formula,the obvious energy-saving effects and so on.
