摘　　要：针对道路早期病害情况,通过纤维碎石封层预防性养护技术对道路已发生初步损坏和即将发生损坏的部位进行修复。某工程实践结果表明:原道路构造深度最小值由0.72 mm增大至0.84 mm,提升幅度高达16.47%,此外,同一点位水系数最大值由189 mL/min下降至103 mL/min,说明养护后道路抗滑、防水性能提升显著。In view ofthe early road diseases,the preventive maintenance technology of fiber gravel sealing layer is used to repair the parts of the road that have been initially damaged and will be damaged.The results of a engineering example show that the minimum depth of the original road structure increases from 0.72 mm to 0.84 mm,with an increase of 16.47%.In addition,the maximum water coefficient at the same point decreases from 189 mL/min to 103 mL/min,indicating that the anti-skid and waterproof performance of the road is significantly improved after maintenance.
