在路面结构设计时,除考虑环境、气候、当地自然资源等因素外,选择经济合理的路面结构是至关重要的。在进行新型结构的研究和推广时,需要采用道路工程经济原理来分析每一结构所需的各项费用,通过综合的分析和比较来作出有关方案的选择,经济分析的目的便是选择“费用—效益”最佳的方案,以供管理层进行科学合理的决策。
In the pavement structure design, in addition to considering the environment, climate, local natural resources and other factors, the choice of economic and reasonable pavement structure is essential. When conducting research and promotion of new structures, we need to use the economic principles of road engineering to analyze the various expenses required for each structure and make a selection of relevant programs through comprehensive analysis and comparison. The purpose of economic analysis is to select “ Cost - benefit ”the best program for management to make scientific and rational decision-making.
