Portable retroreflectometers have been used to compare the reflectivity of the various pavement marking materials. The Mirolux 12 has been used to collect reflectivity data for the products tested for the National Transportation Product Evaluation Program (NTPEP). The Mirolux 12 docs not have a 30 meter geometry, and there has been a desire to explore the possibility of using a retroreflectometer which has a 30 meter geometry which may better simulate the view of a driver. The objective of this report is to compare data taken with the Mirolux 12 and two other portable retroflectometers having the 30 meter geometry.
