Retention of Reflective Raised Pavement Markers (Final)

J. T. Tielking / J. S. Noel

The report contains the results of a study directed toward increasing the retention time of raised pavement markers on asphalt concrete pavement. The kinematics of a tire impacting a pavement marker was studied by high-speed photography. A laboratory investigation of the effect of adhesive type on fatigue strength of asphalt pavement was made. It was found that bituminous adhesive is distinctly superior to epoxy adhesive on new asphalt surfaces. The distinction between bituminous and epoxy adhesive is less pronounced on stiffer (seasoned) pavements. An instrumented pavement marker to record the number of tire hits received was also developed during the study. The circuitry is described and hit count data obtained with instrumented lane line markers is reported.
