Description

This presentation will cover research conducted by South Dakota State University under the Mountain Plains Consortium and with additional funding from South Dakota Department of Transportation. Pavement marking retro reflectivity is achieved by using various materials on PCC and asphalt pavements. This study examined if snow plowing and winter maintenance affected the performance and durability of various pavement marking materials. This study also evaluated the constructability, durability, and visibility of alternative pavement marking materials. Researchers studied seven pavement marking test sections on highways in different regions of South Dakota. Parameters used in the study include:

  • Paint Type (waterborne and epoxy)
  • Paint Thickness
  • Paint Color
  • Reflective Elements (glass beads or other)
  • Line Type (edge and skip)
  • Pavement Type and Surface Prep
  • Winter Maintenance Region (wet freeze and dry freeze)

Data analysis included: 1) retro reflectivity with time, 2) correlations between retro reflectivity and visual rating, 3) effect of the different parameters on retro reflectivity longevity, and 4) cost effectiveness of the different alternatives. An interactive spreadsheet was developed to compare the unit costs of different pavement marking alternatives.
