摘要
本文针对沥青路面预防性养护技术在市政道路中应用的可行性及经济性展开了研究,讨论了沥青路面预防性养护常用技术,分析了其在市政道路沥青路面中应用的可行性,基于沥青路面预防性养护预测模型分析了综合效益指标、效益费用比指标、费用指标、服务寿命变化量等指标,评价了其经济性。研究结果表明:预防性养护技术在市政道路中使用的可行性需依据病害类型及成因判定,预防性养护适用于绝大多数市政沥青路面病害,但在疲劳开裂、推挤等方面不具备有效性,同时对于较大面积的修补病害及坑洞不适宜用预防性养护措施处治;综合效益指标、效益费用比指标、费用指标、服务寿命变化量等指标可以评判预防性养护的经济效益;选择合理的预防性养护方式以及恰当的养护时间,市政道路中应用沥青路面预防性养护技术具备较好的经济性。
This paper researches the feasibility and economy of applying preventive maintenance technology for asphalt pavement on municipal roads.The common techniques for preventive maintenance of asphalt pavement are discussed,the applicability in municipal road asphalt pavement is analyzed,and the economy based on a predictive model for preventive maintenance of asphalt pavement is evaluated,including comprehensive benefit indicators,cost-benefit ratio indicators,cost indicators,and changes in service life.The research results indicate that the feasibility of using preventive maintenance technology on municipal roads depends on the type and cause of the disease.Preventive maintenance is suitable for the vast majority of municipal asphalt pavement diseases,but it is not effective in fatigue cracking,pushing,and other aspects.At the same time,preventive maintenance measures are not suitable for repairing large areas of diseases and potholes.Comprehensive benefit indicators,cost-benefit ratio indicators,cost indicators,and changes in service life can be used to evaluate the economic benefits of preventive maintenance.Choosing a reasonable preventive maintenance method and appropriate maintenance time,the application of asphalt pavement preventive maintenance technology in municipal roads has good economic feasibility.
