Abstract:

This project investigated the installation and performance of snowplowable reflective pavement markers (SRPMs) to determine optimum pavement marker solutions and policies for roadways in Illinois. The research evaluated the performance of five traditional cast-iron and two plastic SRPMs on test sections of both asphalt and concrete pavements. Analysis included 1) comparisons of casting design, casting material, and groove design; 2) assessments on how each factor contributed to pavement marker performance; and 3) development of crash modification factors (CMFs) for quantifying any safety improvement from SRPM use. The results of the SRPM performance evaluation and CMF development were used to provide recommended updates to the Illinois Department of Transportation’s (IDOT’s) departmental policies document TRA-14, which provides guidelines for the use of pavement marking materials (including raised pavement markers) and to IDOT’s Raised Reflective Pavement Marker inspection policy, which gives regional engineers instructions on inspection of in-place SRPMs.
