To Groove or Not to Groove, That Is the Question

This document provides information on an on-going Iowa Department of Transportation study which is focused on measuring recessed versus surface applied pavement marking performance. The study shows that recessed pavement markings can significantly reduce marking damage due to snow plowing and other winter operations. These results show that the yellow center line received much more damage than the white edge line. Based upon one season of evaluation, it was found that incorporating grooved markings into an overall marking program could provide a savings over painting annually. The calculations show that if the material placed within the groove lasts 3 seasons the Iowa DOT would recognize a savings of roughly 17 percent over painting each year and that if the material placed within the groove would perform satisfactorily for 4 seasons, these savings increase to 33 percent. These calculations do not include the safety and economic benefits of having higher performing markings on the roadway 365 days per year. These results should be considered preliminary and will be updated after one and possibly two additional seasons.
