玻璃纤维增强多孔沥青混合料的性能评价

Performance Evaluation of Glass Fiber Reinforced Porous Asphalt Mixture

本研究为提高多孔沥青混合料的路用性能,以沥青和OGFC-13沥青混合料为研究对象,比选玻璃纤维、钢纤维和玄武岩纤维的材料性能,并且针对纤维掺量对沥青混合料路用性能影响进行研究。通过分析室内试验研究结果发现,将适量的玻璃纤维掺加在多孔高黏改性沥青混凝土中,该沥青混合料的高温稳定性和水稳定性等路面性能都有明显的改善。另外,研究还发现在混合料中掺加0.2%的玻璃纤维最为适宜。

In order to improve the road performance of porous asphalt mixture,this study takes asphalt and OGFC-13 asphalt mixture as the research objects,compares the material properties of glass fiber,steel fiber,and basalt fiber,and studies the influence of fiber content on the road performance of asphalt mixture.Through the analysis of indoor experimental research results,it was found that adding an appropriate amount of glass fiber to porous high viscosity modified asphalt concrete significantly improved the high-temperature stability and water stability of the asphalt mixture,as well as its pavement performance.In addition,the study also found that adding 0.2%glass fiber to its mixture is the most suitable.
