Portable Quick Measurement Retroreflectometer For Road markings

Road construction and acceptance: During the road marking construction process, the construction unit can use the road marking instrument to detect the retroreflective performance of the road marking in real time to ensure that the quality of the road marking meets the relevant standards; during the project acceptance stage, the acceptance personnel will also use the instrument to conduct a comprehensive inspection of the road marking to determine whether the road marking meets the design requirements.

Road maintenance and management: Traffic management departments and road maintenance units regularly use road marking instruments to inspect road markings, and promptly understand the wear and reflective performance changes of road markings, so as to reasonably arrange the repair and update of road markings, maintain the good condition of road markings, and ensure road traffic safety.
