Automated Real Time Pavement Marking Retroreflectivity Measurements
Laserlux, an automated real time mobile retroreflectometer is being used to measure the retroreflectivity of pavement lane markings. This vehicle-mounted retroreflectometer provides the measurements needed for proper highway pavement marking management. Quick, simple, reliable, objective, and inexpensive measurements at highway speed are the key to getting a statistically representative sample, without hindering the flow of traffic, nor putting the human operators at undue risk. The Laserlux retroreflectometer has repeatability within a tolerance of 10% as measured under supervised testing by the FHWA. The system can be used for various applications, such as implementing pavement standards, planning re-striping strategies, measuring performance of different materials application methods, holding contractors accountable, and establishing a pavement marking management data base.
