摘要
长寿命沥青路面结构可以显著延长高速公路沥青路面的使用寿命,是解决高速公路沥青路面早期损坏的有效措施。铺筑了长寿命沥青路面结构和其他三种路面结构的试验路,通过沥青路面寿命周期费用分析方法,进行了不同沥青路面方案的经济分析,探讨了长寿命沥青路面的经济适用性。指出初期费用并不是衡量路面结构经济性的关键因素,对于长寿命沥青路面必须进行寿命周期费用的分析,从经济分析的角度建议了不同沥青路面结构的适用场合。
Long-life asphalt pavement which can extend the life of pavement remarkably is effective choice to solve the premature damage.During the study,test sections of four kinds of asphalt pavement structures including long-life pavement are constructed.In this paper,economic analysis of different structures is discussed.Applicability of long-life pavement is evaluated by means of life-cycle cost analysis.
