摘要
针对目前国内外尚没有成型的预防性养护成本效益评估的模式和方法的问题,探讨了路面预防性养护的成本和效益构成及对比分析有关评价方法,且在分析预防性养护对道路寿命周期成本影响的基础上,提出了预防性养护财务分析法。通过比较预防性养护方案与零预防性养护方案诸多方面的差异,考虑收费公路业主的过路费收入等,提出采用净年值差这个经济指标评估预防性养护对道路寿命周期内成本效益的贡献值。案例及敏感性分析验证了该方法的可靠性及实用价值。
Up to now there is no a mature model and approach of evaluating the cost and benefit of pavement preventive maintenance （PPM） at home and abroad. The cost and benefit frame of PPM was discussed and contrasted and analysis of some evaluating methods were made. Based on analyzing how PPM influences the life-cycle cost of roads, an approach of PPM financial evaluation was demonstrated. Through comparing the differences between PPM and ＂do nothing＂ strategy and considering the toll earning in toll roads, net annual value difference was applied to evaluate the contribution value of PPM to road life-cycle cost and benefit. The case study proved the reliability and utility of this approach.
