沥青混凝土路面结构全寿命周期费用分析方法

Analysis Method of the Full-Life Cycle Cost for Asphalt Pavement

文中将全寿命周期费用的理念融入沥青混凝土路面结构的费用分析中。沥青混凝土路面在全寿命周期中发生的费用支出包括建设期的初期建设费用以及在运营期内发生的修补养护费用。运营期内的费用支出主要包括车辙修补费用和开裂修补费用。车辙的预估模型采用AASHTO模型的修正形式。开裂修补费用以路面结构的疲劳开裂率为依据进行计算。全寿命周期费用分析方法可为路面设计管理提供参考,以正确评估道路在全寿命周期内发生的费用支出。

The full-life cycle cost concept is pavement. Expenses of asphalt pavement in applied into the cost analysis of the structure of asphalt the full-life cycle include initial construction in the construction period and repair and maintenance costs in the operation period. Expenses in the operation period include the rut repair costs and crack repair costs. Prediction of the rut applied the corrector form AASHTO model. The calculation of crack repair costs is based on the fatigue cracking of pavement structure. Full-life cycle cost analysis method can be used to provide reference for the pavement design and management to correctly evaluate the costs occurred in the full-life cycle.
