公路水运试验检测技术在道路工程中的应用与发展研究

Research on the application and development of highway water transport test detection technology in road engineering

沥青混凝土作为路面材料已广泛应用于道路工程,为了评估公路水运试验检测技术-压电超声波技术的可行性,文章使用压电超声波技术进行道路沥青混凝土损伤检测的研究。结果表明,沥青混凝土的超声波速度与空隙率成反比,例如在饱和水环境和干燥环境中的超声波速度分别为2442m/s、2321m/s。损伤检测技术可以有效地识别结构损伤,提高道路工程材料的设计和维护效率。

Asphalt concrete as a pavement material has been widely used in road engineering.In order to evaluate the feasibility of highway water transport test detection technology-piezoelectric ultrasonic technology,this paper uses piezoelectric ultrasonic technology to detect road asphalt concrete damage.The results show that the ultrasonic velocity of asphalt concrete is inversely proportional to the voidage,such as 2442 m/s in saturated water environment and 2321 m/s in dry environment.In addition,damage detection technology can effectively identify structural damage,thereby improving the design and maintenance efficiency of road engineering materials.
