摘要
为解决沥青路面车辙病害日益严重的问题,对抗车辙沥青路面结构进行研究。采用抗车辙级配并掺入抗车辙剂设计了两种抗车辙路面结构,对材料性质进行了测试,确定了混合料的级配及沥青含量,并进行室内试验以评价其路用性能。研究结果表明,使用抗车辙级配及掺加抗车辙剂,均可提高沥青混合料的抗车辙性能,且掺加抗车辙剂效果更加显著。
For the purpose of solving the increasingly serious problem of rutting on asphalt Pavement,research on anti- rutting asphalt pavement structure has been carried on. Anti- rutting gradation is adopted and anti- rutting additive is mixed to design two types of anti- rutting asphalt pavement,properties of the materials are tested,mixture gradation and asphalt content are determined,and pavement performance are evaluated based on laboratory experiment. Results show that anti- rutting gradation and anti- rutting additive can both improve the anti- rutting performance of asphalt mixture,and effect of anti- rutting is relatively more significant.
