摘要和关键词

摘要: 为了科学测度道路路面的潜在病害程度,合理制定路面全生命周期的维护策略,探究多阶段维修养护的道路路面性能衰变模型的构建形式。文章基于现有模型建立多阶段沥青路面性能衰变模型,调整该模型的性能折减系数、决定维修的时刻和衰变模式因子,分析不同参数条件下性能衰变特性,构建不同维修养护阶段下的衰变模型;探讨多阶段模型参数的引入合理性及其取值范围,讨论不同参数对性能的影响;当某阶段相关参数已知时,预测下一阶段的性能衰变曲线。研究发现:使用性能指数的大小与折减系数、模式因子有关,而曲线衰变趋势与三者均相关;结合道路性能等级划分方式,确定不同维修水平与道路性能等级的定量关系,有利于从道路路面全生命周期内多阶段维修养护的多种策略中获取最优策略,为后续的资源配置和道路施工提供可靠参考。

Abstract and Keywords

Abstract: In order to scientifically measure the potential disease degree of road pavement, reasonably formulate maintenance strategies for the full life cycle of road pavement, this paper explores the construction form of road pavement performance decay model for multi-stage maintenance. Based on the existing models, a multi-stage asphalt pavement performance decay model is established. By adjusting the performance reduction coefficient of the model, the maintenance time and decay mode factor are determined, the decay characteristics of pavement service performance with different parameter conditions are analyzed, and the decay models of pavement service performance in different maintenance stages are derived. The rationality and value range of the parameters of multi-stage model are discussed, and the influence of different parameters on pavement performance decay is probed. The decay curve of pavement performance with time in the next stage is predicted when the relevant parameters are known. It is found that the pavement performance index is related to the reduction coefficient and decay mode factor, and the decay trend of pavement performance is related to all three. The quantitative relationship between different maintenance levels and road performance levels is determined by using the road performance grade classification methods, which is conducive to obtaining the optimal strategy from the multi-stage maintenance strategies for the full life cycle of road pavement, and providing a reliable reference for the subsequent resource allocation and road construction.
