Centerline Rumble Strips Safety And Maintenance Impacts

Soon after implementation of centerline rumble strips in Georgia around 2005-2006, the Georgia Department of Transportation (GDOT) observed pavement distress and deterioration at one of the centerline rumble strips sites. As no definitive correlation has been drawn between centerline rumble strips and pavement deterioration, a literature review and a survey were conducted to investigate this issue. Of the 28 state DOTs that responded, 10 state DOTs indicated that they encountered adverse effects associated with centerline rumble strips. Of the 10 state DOTs, five identified accelerated pavement deterioration as an issue, three identified pavement failure as an issue, seven identified noise as an issue. However, as state DOTs recognize the benefits of centerline rumble strips, nearly every state DOT surveyed (27 out of 28) is currently planning or constructing centerline rumble strips despite the possibility of adverse effects. In addition, the literature review and survey results reveal that any adverse effects of centerline rumble strips appear to arise on a case-by-case basis rather than appearing as a systematic issue. Thus, the recommendation for GDOT is that it should continue its centerline rumble strips program with several considerations and amendments to existing design policies: the pavement on which the centerline rumble strips will be installed, the strength of the longitudinal joint, and effects to nearby residents.
