玻璃纤维增强沥青混凝土的力学参数测量及路用性能对比分析
首发时间:2007-01-23
摘要:本文基于弹性理论,对AC13型普通沥青混凝土和玻璃纤维增强沥青混凝土进行了力学参数(间接拉伸劲度模量)测量,进一步通过重复荷载间接拉伸疲劳、车辙、水稳定性试验,验证了玻璃纤维对沥青混凝土路用性能的改善效果,分析了玻璃纤维在沥青混凝土中的作用和强度形成机理,为玻璃纤维增强沥青混凝土路面设计提供了理论参考。

Contrast Analysis on Mechanics Parameter and Pavement Performance of the Glass Fiber-reinforced HMA
Abstract:To evaluate the effect of the glass fiber reinforced the HMA(hot mix asphalt),laboratory investigations are conducted on the samples with and without glass fibers. The testing undertaken in this research comprises of the indirect tensile test, rutting test, repeated loading indirect tensile test and moisture susceptibility test. The utilization of the glass fiber shows consistent result and it is found the addition of glass fiber does improve the main property of HMA. The interactive mechanism of the glass fiber on the HMA is analyzed to guide the asphalt pavement design by contrasting experimental data.
Keywords: glass fiber HMA (hot mix asphalt) mechanics parameter pavement performance
