无损检测技术评估和检测道路性能

目前,在我国的基础设施管理方面,存在维修工作安排不当、养护维修不及时、维修预算支出庞大等问题。因此,为了保障道路安全,防止发生灾难性的破坏,需要采取快速、有效的养护管理方法,以提高道路的使用寿命。根据美国材料与试验协会(ASTM)路面状况评价标准,本文介绍了五种道路无损检测技术和设备:落锤式弯沉仪、探地雷达、宏观构造深度、国际平整度指数和面波的频谱分析,并分别介绍了每种检测技术的工作原理和运用方法,以指导相关人员结合实际合理选用。运用这几种检测方法将会在不封闭交通的情况下加快评估速度,并为搭建一个高效、智能的路网监测系统提供技术支持,为道路的可持续发展、资金的高效利用提供切实可行的方法。

Nondestructive Testing Method to Assess and Detect Road Performance

At present, China is faced with major problems in infrastructure management, such as improper scheduling and belated implementation of maintenance work or huge maintenance budget outlays. As such, it is essential to implement rapid and effective management measures to ensure road safety, prevent catastrophic damage, and increase economic growth. In this paper, five nondestructive road testing methods and their associated testing equipment are introduced according to the American Society for Testing and Materials. These include the falling weight deflectometer, ground penetrating radar, macro texture depth, international roughness index, and spectral analysis of surface waves. The operating principles and applications of each testing method are elaborated to guide relevant personnel to make a reasoned choice according to their actual situation. The application of these testing methods will accelerate the assessment of projects without traffic closures, likely provide a new approach for establishing a high-efficiency intelligent road network monitoring system, and will provide a practical and feasible method for sustainable road development and the efficient utilization of capital.
