摘要
随着我国高速公路沥青路面的大面积修建,道路在运营状况下产生了一定程度的破坏。为了延迟或降低道路破损状况,国内外采用了预防性养护技术,以延长道路使用年限,减少道路维修养护的费用,以及保持道路长期处在良好的服务状态等要求。准确分析沥青路面处在预防性养护阶段的力学性能,可以有效地对路面的各项性能指标状况进行预判,做出合理的处置方案以保证道路处于较好的技术状态。本研究通过ANSYS软件对预防性养护阶段的沥青路面裂缝和车辙性能进行力学分析,取得了比较满意的结果。研究结果对预防性养护阶段的沥青路面性能的力学分析具有一定的参考价值,可以更好的了解沥青路面预防性养护阶段道路的应力、应变情况。
With the increasing construction of asphalt pavement of highways in China, road damage occurred at different degrees during operation. In order to delay or reduce the road damage degree, the preventive maintenance technology has been applied both in China and abroad to prolong the service life of the road, reduce the cost of road maintenance, and finally to make the road in good service conditions for a long time. Accurate analysis on the mechanical performance of asphalt pavement in preventive maintenance stage can effectively predict various performance indicators, and make reasonable maintenance plan to ensure the road in the better technical conditions. In this study, the cracking and rutting of asphalt pavement performance during preventive maintenance stage has been analyzed by ANSYS software with a satisfactory outcome. The results of this study are of reference value to the mechanical analy-sis on asphalt pavement during preventive maintenance stage and can provide better understanding of the stress and strain of the road during preventive maintenance.
