不同纤维掺量对岩沥青微表处应用技术分析

Application of different fiber content in Rock Asphalt Micro-surfacing

通过对稀浆混合料的拌合试验、粘聚力试验、湿轮磨耗试验、负荷轮粘砂试验,分析了不同纤维掺量对岩沥青微表处混合料路用性能的影响。同时铺筑了试验路段,并对其经济效益以及社会效益进行了分析。结果表明:适量的纤维掺量显著增强了岩沥青微表处混合料的粘聚力和粘稠度,并且纤维对岩沥青微表处混合料的粘附性、抗滑性能、抗变形能力、疲劳寿命等有明显改善作用。

Through mixed slurry mixture test,cohesion test,wet track abrasion test and load wheel sand test,it is concluded that different fabric content influence the pavement performance of the rock asphalt micro-surfacing mixture. The test section is paved. At last its economic and social benefits are analyzed. The results show that the right amount of fabric content greatly can enhance the cohesion and viscosity of asphalt mixture,in addition,fiber has significant improvement effect on the adhesion,the skid resistance,the anti-deforming capability and fatigue life of asphalt mixture.
