摘　　要：OGFC开级配沥青混合料因其良好的抗滑及排水性能而被广泛应用到高等级沥青路面养护工程当中。本研究将高粘沥青及玄武岩纤维应用到OGFC薄层罩面混合料当中来改善沥青路面的路用性能。通过对不同设计空隙率OGFC-10薄层罩面混合料相关路用性能研究得出:随着设计空隙率的减小,混合料高温抗车辙、抗水损害、低温抗开裂性能均逐渐增强,抗滑及排水性能均逐渐降低,综合考虑,设计空隙率为10%的OGFC-10薄层罩面混合料整体路用性能最优。OGFC open graded asphalt mixture is widely used in high-grade asphalt pavement mainte⁃nance engineering because of its good skid resistance and drainage performance.In this study,high vis⁃cosity asphalt and basalt fiber are applied to OGFC thin-layer overlay mixture to improve the road perfor⁃mance of asphalt pavement.Through the research on the relevant road performance of OGFC-10 thin-layer overlay mixture with different design void ratio,it is concluded that with the decrease of design void ratio,the high-temperature rutting resistance,water damage resistance and low-temperature cracking re⁃sistance of the mixture are gradually enhanced,and the skid resistance and drainage performance are gradually reduced.Comprehensively considered,the overall road performance of OGFC-10 thin-layer overlay mixture with design void ratio of 10%is the best.
