剑麻纤维沥青混合料冻融劈裂试验研究

Trial study on freeze thawing split-strength of asphalt mixture with sisal fiber

为研究剑麻纤维对沥青混合料的水稳定性的影响,选用AC-13 SBS改性沥青混合料为对象进行冻融劈裂试验,测定了沥青混合料在受到水损坏前后劈裂破坏的强度比,试验研究结果显示掺入适量剑麻纤维能有效增强沥青混合料冻融劈裂强度。

In order to study the influence of the water stability of asphalt mixture, take AC-13 SBS modified asphalt mixture as the research object for freeze-thaw split test, measure the splitting failure intensity ratio of the asphalt mixture pre and post water failure. Experimental re- suits show that appropriate incorporation of sisal fiber can effectively enhance the freeze thawing split-strength of asphalt mixture.
