Do rumble strips damage the pavement?
Research has shown that rumble strips cause no noticeable degradation of new pavement. They also require little or no maintenance. In Alaska, rumble strips are not installed on pavement in poor condition. In a Kentucky study, pavement deterioration and the accumulation of snow and ice in the rumble strip depression were evaluated. Pavement deterioration along the centerline joint was noted on the Mountain Parkway and Daniel Boone Parkway. However, it was noted this was a retrofit application and pavement performance was poor before the rumble strip placement. Other rumble strip installations did not result in any significant pavement deterioration when placed on new pavement. Water and ice accumulation in the centerline rumble strip was determined not to be an issue. The Federal Highway Administration, Office of Safety, understood maintenance crews were initially concerned that heavy traffic would cause shoulder pavements with rumble strips to crumble faster, or that the freeze-thaw cy
