The bridge deck of a high-speed railway project utilizes spray-applied rubber asphalt waterproofing coating, and due to the demand for extreme low-temperature environment, a委托检测 was conducted. The technical team, based on the Q/CR 517.2-2023 standard, focused on testing the low-temperature flexibility and tensile strength, discovering that the samples exhibited cracks at specific low temperatures and the tensile strength was significantly below the standard values. Through the precise analysis of the professional team, a CMA-certified report was issued, helping the project to promptly replace qualified materials and avoid potential structural corrosion risks. The laboratory is capable of rapid testing and has served numerous similar projects.
