ASTM D4061 Traffic Road Retro Reflectometer
Digital Traffic Road Retro Reflectometer for Marking Line and Vertical Sign is a professional measuring instrument used to measure the reflectivity of road markings. The measured parameters are the retroreflective coefficient R’or the specific brightness of the marking line in mcd. lx-1. m-2. The instrument is simple to operate and reliable in measurement. It can be used not only in laboratory environment, but also in field measurement. It is an optimum instrument for measuring the reverse reflection performance of pavement markings, such as production, quality supervision, engineering construction and supervision units.
