摘要：AbstractRecently, the pavement maintenance technologies have been fully studied at home and abroad, especially for the asphalt pavement. However, there hasn’t been much research on evaluating the different maintenance technologies based on their economic and benefit aspects because of the lack of practical applications and actual engineering applications that have always been a challenge. Based on the existing engineering economic theory, combining the factors of pavement residual value and maintenance input cumulatively, this paper proposes a new economic-benefit index and builds an economy-benefit model in accordance with the time increasing benefit and the evaluation of three maintenance treatments. In the end, results are presented and discussed in the conclusion.
