纤维已成为提高沥青混合料路用性能必不可少的材料，文中从玄武岩纤维和木质素纤维技术性能、沥青混合料路用性能，以及经济效益方面分析了玄武岩纤维在贵州省沥青路面中应用的可行性。结果表明，玄武岩纤维在技术性能、沥青混合料高温稳定性和水稳定性方面均优于木质素纤维，但经济成本高于木质素纤维，因此，还需进一步通过试验路铺筑来验证其在贵州省应用的可行性。

Fiber has been a necessary material in improving the pavement performance of asphalt mix‐ture .Based on the utilization of fiber material in Guizhou ,the feasibility of basalt fiber was analyzed from the following aspects :the technical performance of basalt fiber and lignin fiber ,the pavement per‐formance of asphalt mixture and its economic benefits .Our study result shows that basalt fiber is su‐perior to lignin fiber in its technical performance ,stability in high temperature and stability in water . However ,the economic costs of basalt fiber are also higher than lignin fiber .As for its feasibility in Guizhou ,there still needs further verification and support through much more experiments and trial pavement section .
