摘　　要：科学合理的沥青路面预防养护使用性能后评估,对路面养护科学决策具有十分重要的现实意义。在相邻两条高速公路上进行养护技术调查,参照赣粤高速公司提供的技术指标以及现场调研路面状况,依据灰色理论预测方法建立GM(1,1)模型,对江西省高速公路沥青路面所应用的6种预防养护技术进行路面使用性能后评估。根据各指标随时间的衰变特征,结合交通等影响因素,评估其使用性能。结果表明,就地热再生技术使用性能较好,但抗滑性能受到旧集料质量的影响,SRI年均衰减速率约为3.0%,衰减较快;微表处技术PCI与SRI年均衰减率约为3.9%,相比与其他养护技术衰减得较快;罩面类养护技术在技术指标不同的原路面进行养护,其指标衰减相差不大,存在养护技术浪费。A scientific and reasonable evaluation of the performance of asphalt pavement after preventive maintenance is of great practical significance to the scientific decision-making of pavement maintenance.In the paper,maintenance technology investigation is carried out on two adjacent expressways,by referring to the technical indicators provided by Gan-Yue Expressway Company and the on-site investigation of the pavement condition,a GM(l,1)model is established based on the gray theoretical prediction method,and the performance of the six preventive maintenance technologies applied to asphalt pavements of highways in Jiangxi province after the use of the performance of the pavement is evaluated.According to the time decay characteristics of each index,combined with the traffic and other influencing factors,its performance is assessed.The results show that in situ thermal regeneration technology use performance is better,but the skid resistance is affected by the quality of the old aggregate,the average annual decay rate of SRI is about 3.0%,the decay is faster;micro-surface treatment technology PCI and SRI average annual decay rate are about 3.9%which is faster compared with other maintenance technology of the decay;and overlay type of maintenance technology in the technical index of the different original pavement for maintenance,the indicators of its decay is not much different,there is a waste of maintenance technology.
