摘要
高速公路承载不同地区间物资运输、人员流动的重要任务,沥青路面的养护与维修已成为高速公路维护的重要课题。为了进一步研究高速公路使用性能的衰减规律,文中依托沿海某地区高速公路实际检测数据,提出高速公路的衰减规律模型。经过验证,该衰变模型在沿海地区各路段均有良好的适用性,且具有较高的精度,可以用于沿海地区高速公路路面性能的预测,进而为路面的养护和维修对策的制定提供理论依据。
Expressway bears the important task of material transportation and personnel flow between different areas,therefore,the maintenance of asphalt pavement has become an important issue.This paper proposes a model of based on the actual detection data of expressway in a coastal area to further study the attenuation law of expressway performance.Moreover,the decay model has good applicability and high accuracy in all sections of coastal areas.Therefore,it can be used to predict the performance of expressway pavement in coastal areas,which provide theoretical basis and countermeasures for pavement maintenance.
