基于“经济-效益”指标的沥青路面养护方案评价模型研究

Recently, the pavement maintenance technology has been fully studied at home and broad, especially the asphalt pavement; however, there has been less research on the study of how to distinguish the advantages and disadvantages of these maintenance technologies, especially the economy differences. Difficult to multipurpose contrast, and theoretical strong but lack of practical application are the problems to the existing research, and also poor in actual engineering applicability. Based on the existing engineering economics, combined with the factors of pavement residual value and maintenance input cumulatively, this paper puts forward a new economic-benefit index, build a economy-benefit model in accordance with the time increasing benefit, and evaluate three maintenance scheme. The results are the same to this paper's conclusion.
