摘要
针对现有养护工程方案比选中片面关注初期投资成本的问题,以全寿命周期成本分析为基础,对沥青路面加铺方案寿命周期内的成本进行全面分析,确定了加铺方案寿命周期成本分析的组成部分,并建立各阶段的寿命分析计算模型,通过实例分析和不同的公路沥青路面加铺方案在项目全寿命周期内的经济影响的比较,一方面证明寿命周期成本分析在工程应用中的经济价值,另一方面证明橡胶沥青不仅具有突出的路用性能,也具有良好的经济环境效益。通过寿命周期成本分析可获得最大经济社会效益的方案,为大规模养护工程提供必要的技术支撑。
Based on problem of focusing on initial investment costs in current maintenance project,made a comprehensive analysis of the cost in the life cycle of pavement maintenance program using LCCA and determined the components of LCCA and calculation model of each stage.Finally,analyzed and compared the economic impacts of different planused an example for pavement overlay project in the whole life cycle.On the one hand,it found the LCCA was useful in engineering application.On the other hand,it proved that rubber asphalt not only had outstanding performance,but also had good economic and environmental benefits.Through LCCA,the most economic and social benefits can be obtained,which will provide the necessary technical support for the upcoming large-scale maintenance projects.
