Based on the deficiency of our present scheme decision- ma king, this thesis proposes that it should emphasis life -cycle-cost comparison in the scheme decision- making; constructing a reasonable L C C system has critical significance. In this paper, based on the analysis of the pavement surface layer and base, elaborated the structure characteristics and road performance of the pavement program of Zeng cong high way project. Compare the strengths and weaknesses of the different surface layer and base materials. Meanwhile, predict the life of this article’s program according to the foreign study. Through life-cycle cost analysis (LCCA), Reference expressway cost control at home and abroad, to build pavement life cycle cost calculation model, application of the model program of pavement economic comparison.
