高等级公路沥青路面养护工程多目标体系的建立

Establishment of Multiobjective System for Maintenance Engineering of High-Grade Highway Asphalt Pavement

以贵州省高等级公路沥青路面养护工程的多目标性为依托,在充分调研其高等级公路沥青路面技术状况及养护管理模式的基础上,建立起以公路资产全寿命周期的保值增值为宗旨,以延长路面使用寿命为中心,以保证路面安全水平为底线,以提高路面服务能力为出发点,以成本效益比为主要控制因素的五大目标体系,并对其初步应用进行分析。

Replying on the multi-objective of maintenance engineering of high-grade highway asphalt pavement in Guizhou Province, with sufficient investigation of technology condition and maintenance management mode of the high-grade highway asphalt pavement, the five target system is established, which takes preserving and increasing the value of whole life cycle of the highway assets as the aim, prolonging the service life of the road as the center, ensuring road safety level as the bottom line, improving the pavement service capacity as the starting point, cost-benefit ratio as the main control factors, and the prelimi- nary application is analyzed.
