Abstract:In this report, region-specific Retro-reflectivity Performance Curves are presented and discussed as a function of pavement marking materials, AADT, terrain, surface type, line color, line type, road bound direction, and road name. In addition, laboratory aging, and abrasion test results are presented and discussed. In addition to this written report, five separate dynamic graphical tool were submitted; one for each of the Colorado regions. A clear and concise description of these tools are discussed and a few examples are given and interpreted. The intention of these dynamic tools is that the road managers will continue adding data, and making corrections to the database presented. Another objective of this report, is to allow the users at CDOT to better determine appropriate times to restripe roads, increase cost efficiency, and overall road safety attributed to road striping practices in Colorado.
