沥青混凝土路面养护对维持良好的路面性能具有重要的意义,养护决策的成功与否与预防性养护的时机密切相关,正确的养护时机决策方法可达到事半功倍的效果。通过对常用预防性养护最佳时机决策方法研究结果表明:目前预防性养护最佳时机决策方法还不够完善,对路面性能评价指标太单一,由此提出以经济分析法中的效益-费用分析法为基础,优化效益计算指标和费用模型,使分析结果和养护工程实际更加吻合,为预防性养护最佳时机决策提供了理论依据。
Asphalt concrete pavement maintenance is of great significance to maintaining good pavement performance. The success of maintenance decision-making is closely related to the timing of preventive maintenance. The correct maintenance timing decision-making method can achieve a multiplier effect. The research on the best timing decision method for preventive maintenance shows that the best decision-making method for preventive maintenance is not yet perfect, and the evaluation index of pavement performance is too simple. Therefore, the economic benefit analysis-cost analysis As the basis to optimize the calculation of benefit indicators and cost models so that the analysis results and conservation projects more in line with the actual project for the preventive maintenance of the best timing to provide a theoretical basis.
