ABSTRACT

Reasonable establishment of maintenance prediction mechanism plays an important role in service performance and long-term performance of asphalt pavement. The presented study proposed a comprehensive maintenance evaluation system framework of asphalt pavement based on the full-cycle. Firstly, Pavement maintenance cycle was divided into five stages and three important maintenance opportunities. Secondly, according to the theoretical formula method, the single index of pavement maintenance was studied, and the relationship between single index and service life was established. Combined with the empirical formula method and the measured data method, the evaluation standard of the full-cycle asphalt pavement comprehensive maintenance system was determined. Finally, based on the background of Har-tong expressway, the evaluation standard of comprehensive maintenance system in Heilongjiang Province of China under different maintenance periods was established. The results showed that the full-cycle comprehensive maintenance evaluation system can effectively predict the key nodes of asphalt pavement maintenance. In addition, the relevant maintenance standards can be formulated according to the driving data of different regions, which is helpful to establish an accurate maintenance evaluation system. This is conducive to saving maintenance resources, improving maintenance efficiency, and providing reference for future pavement maintenance construction.

摘要

合理建立养护预测机制对沥青路面的服役性能和长期性能具有重要作用。本研究提出了基于全周期的沥青路面综合养护评价体系框架。首先，将路面养护周期分为五个阶段和三个重要养护时机。其次，根据理论公式法对路面养护的单一指标进行了研究，建立了单一指标与使用寿命的关系。结合经验公式法和实测数据法，确定了全周期沥青路面综合养护体系的评价标准。最后，以哈通高速为背景，建立了黑龙江省不同养护周期的综合养护体系评价标准。结果表明，全周期综合养护评价体系能够有效预测沥青路面养护关键节点。此外，还可以根据不同地区的行驶数据制定相关的维修标准，有助于建立准确的维修评估体系。这有利于节约养护资源，提高养护效率，为以后的路面养护施工提供参考。结果表明，全周期综合养护评价体系能够有效预测沥青路面养护关键节点。此外，还可以根据不同地区的行驶数据制定相关的维修标准，有助于建立准确的维修评估体系。这有利于节约养护资源，提高养护效率，为以后的路面养护施工提供参考。结果表明，全周期综合养护评价体系能够有效预测沥青路面养护关键节点。此外，还可以根据不同地区的行驶数据制定相关的维修标准，有助于建立准确的维修评估体系。这有利于节约养护资源，提高养护效率，为以后的路面养护施工提供参考。
