摘　　要：为研究空隙率对沥青混合料路用性能的影响,设计不同的空隙率,对玄武岩纤维高黏降噪型OGFC-10超薄磨耗层性能展开研究.对OGFC-10混合料进行配合比设计,使空隙率分别为10%、16%、22%,通过析漏损失及肯特堡飞散试验确定OGFC-10-10%、OGFC-10-16%、OGFC-10-22%三种超薄磨耗层最佳油石比分别为6.5%、5.2%、3.5%.通过对不同空隙率的OGFC-10混合料路用性能研究得出,随着空隙率的增大,OGFC-10混合料高温抗车辙、抗水损害、低温抗开裂及层间黏结能力均逐渐降低,排水及抗滑能力均逐渐增强;空隙率为10%时,OGFC-10混合料整体路用性能最优.In order to study the influence of void ratio on the pavement performance of asphalt mixture,different design void ratios are selected to study the OGFC-10 ultra-thin wearing layer with high viscosity and noise reduction of basalt fiber.The design void ratios are 10%,16%and 22%respectively.The mix proportion of OGFC-10 mixture is designed,and the optimum asphalt aggregate ratios of OGFC-10-10%,OGFC-10-16%and OGFC-10-22%are determined to be 6.5%,5.2%and 3.5%respectively through leakage loss analysis and Cantanbro stripping test.Through the research on the road performance of OGFC-10 mixture with different void ratios,it is concluded that with the increase of void ratios,the high-temperature resistance to rutting and water damage and the low-temperature resistance to cracking and interlayer adhesion of OGFC-10 mixture gradually decrease,while the ability to drain and resist sliding gradually increases.When the void ratio is 10%,the overall road performance of OGFC-10 mixture is the best.
