| 摘 要： | 路面预养护效益分析是路面预养护技术的核心,是比选预养护方案和确定实施时机的前提。根据美国等路面预养护效益分析的经验,结合我国公路养护技术水平,对沥青混凝土路面预养护效益分析中的效益指标、效益计算基线和预养护时间范围展开了讨论;进而,提出我国现阶段沥青混凝土路面预养护分析中效益指标选用建议和它们计算下基线的参考值,以及预养护时间范围的控制指标和控制标准的建议值。

| Abstract: | The benefit analysis,which is the key procedure of pavement preventive maintenance technique,is the prerequisite to choose the preventive maintenance treatment measures and determine the optimal time to carry out.In reference to the practice experiences of pavement preventive maintenance in America,Canada etc.,the benefit indexes,benefit cutoff values and the time range of preventive maintenance in conjunction with the national pavement maintenance technical level are discussed.Therefore,benefit indexes and corresponding lower benefit cutoff values in benefit analysis relating to present time are proposed,the indexes using to decide whether the preventive maintenance should be applied and its numerical ranges are then given. |

| Keywords: | asphalt concrete pavement pavement preventive maintenance benefit analysis benefit indexes benefit cutoff values optimal time of pavement preventive maintenance |
