Standard Method of Test for Measuring Retroreflectivity of Pavement Marking Materials Using a Mobile Retroreflectivity Unit
standard by American Association of State and Highway Transportation Officials, 2014



AASHTO TP 111-14 (2020) covers measurement of the retroreflective properties of dry, horizontal pavement marking materials, using a Mobile (vehicle-mounted) Retroreflectivity Unit (MRU) operated at posted roadway speeds at a prescribed geometry. The prescribed geometry corresponds to the European Committee for Standardization (CEN) geometry and is the standard geometry adopted by ASTM E 1710.

This test method ensures that night-time visibility provided by pavement markings is adequate. This applies to the measurement of the pavement marking retroreflectivity using mobile instruments.
