Evaluation of Snowplowable, Retroreflective Raised Pavement Markers
The Maryland State Highway Administration (SHA) participated in the AASHTO National Transportation Product Evaluation Programs (NTPEP) evaluation of snowplowable raised pavement markers (SRPM). The NTPEP evaluates products to determine their applicability for use by the various Departments of Transportation. The scope of work for this study included both laboratory and field testing. Field tests were conducted on eighty of each SRPM model. Forty of each SRPM model were installed on a Portland cement concrete (PCC) section of roadway and forty were installed on a Hot Mix Asphalt (HMA) section of roadway. The laboratory potion of the study, reported by the Georgia Department of Transportation, included tests of the coefficient of luminous intensity, abrasion resistance, compressive strength of reflectors, and bond strength. This report details the field study and its results. The report also summarizes the major findings of the Evaluation.
