Quantification of the Physical Properties Required of Raised Pavement Markers and Accelerated Laboratory Testing, Summary Report.

摘要

In this project, University of South Florida researchers worked to improve current RRPM designs and to develop new laboratory tests that better predict marker performance in the field. A literature review of current RRPM use on U.S. highways among all the states showed that the main RRPM brands approved on U.S. highways include 3M, Rayolite, Ennis, and Apex. A map of RRPM use in the U.S. showed that most RRPMs are installed in southern regions. In northern tiers, some states have replaced RRPM models that cannot be snowplowed with ones that can be.
