Abstract
Whether the tests result of road damage rate is accurate or not, it is affected by many factors. The article describes the measurement standards developed for pavement damage detection equipment, including pavement damage measurement standard devices and pavement damage standard test blocks. The pavement damage measurement standard device detects pavement cracks through image recognition technology and measures its geometric parameters. The pavement damage standard test block simulates the pavement texture using engineering plastics, and then uses a laser engraving process to process typical pavement cracks to realistically reproduce the actual form of pavement cracks. The article gives a metrological traceability diagram of the amount of pavement damage detection equipment, and carries out repeatability tests and stability tests to verify the measurement standards.
