当前,在路面寿命周期费用评价的实施上还未考虑可选方案整体服务能力的差异性。基于该评价的做法可能达不到道路用户和高速公路管理者的预期目标,评价路面性能需要评估不同设计、养护、重建项目的价值,并把管理者和用户结合起来考虑,这样的评价才是最佳的。该文介绍了两种方法来确定不同路面性能水平的费用量,其中一种使用了名为路面性能质量指数的定量方法,该方法可用来比较不同路面项目的整体性能差异;另一种方法基于建立定量年费用和路面服务能力之间的某种关系。对每种方法而言,都提出了一种分析框架,把寿命周期费用与路面性能因素结合起来考虑。
At present, the difference in the overall service capability of alternative solutions has not been considered in the implementation of the pavement life cycle cost evaluation. Evaluations of pavement performance need to evaluate the value of different design, conservation, and redevelopment projects based on the evaluation, which may not meet the expectations of road users and highway managers, and the combination of managers and users is such an assessment The best. This paper presents two methods to determine the cost of different pavement performance levels, one of which uses a quantitative method called Pavement Performance Quality Index that can be used to compare the overall performance differences of different pavement items; the other is based on Establish a relationship between quantitative annual costs and pavement service capabilities. For each method, an analytical framework is proposed that takes into account life cycle costs in combination with pavement performance factors.
