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。
Pavement maintenance efficiency analysis is the core of pavement pre-curing technology, is to compare the pre-maintenance programs and determine the timing of the implementation of the premise. According to the experience of pavement maintenance benefit analysis such as the United States, and the technical level of road maintenance in our country, the benefit index, benefit calculation baseline and pre-curing time range of pre-curing benefit analysis of asphalt concrete pavement are discussed. Furthermore, Analysis of the selection of benefit indicators in the pre-curing analysis of concrete pavement and their reference values for calculating the baseline, as well as the recommended control values and control standards for the pre-curing time range.
