泡沫沥青混合料配合比设计试验

Experimental Research on Proportion Design of Foamed Asphalt Mixture

泡沫沥青混合料配合比设计的研究主要包括沥青的发泡、集料级配的确定、拌合用水量和最佳沥青用量的确定。结合国内外研究成果,提出泡沫沥青混合料配合比设计方法和步骤。通过原材料的性能分析和筛分通过率确定集料配比,采用重型击实试验和劈裂试验分别确定拌合用水量和最佳沥青用量。

The research on proportion design of foamed asphalt mixture includes： foaming of asphalt, gradation, and the best amount of mixing water and asphalt. Its design method and steps are put forward. By analyzing the properties and passing rate, the proportion of aggregates is ascertained. The best amount of mixing water and asphalt is also ascertained aspectively through the heavy tamping test and the splitting test.
