Appendix D. Pavement Marking Retroreflectivity Degredation Graphs

Previous | Table of Contents | Next

This appendix contains graphs showing the retroreflectivity degradation of each test section that lasted at least 1 year. The y-axes on the graphs represent retroreflectivity (mcd/m²/lux), and the x-axes represent the age of the markings in days since application. For more specific marking information, refer to appendix C. Note that the y-axes vary in scale for the different graphs.
