Abstract:

The Georgia Department of Transportation (GDOT) uses raised pavement markers (RPMs) widely on roads

throughout the State to increase road safety. Each of the approximate 3 million RPMs in Georgia was placed

manually. Unfortunately, RPMs do not last as long as the road surface meaning they need to be replaced

several times throughout the life of a road. There is a strong desire to remove the RPMs prior to placing new

ones. GDOT contracted with the Georgia Tech Research Institute (GTRI) for a feasibility study of new

methods of removing RPMs.

Currently, RPM removal is a manually intensive process. To remove RPMs, workers use either a

reciprocating chisel or an eradicator/scarifier. The approach that GTRI proposed was to use a high speed

machining technique to mill the marker off of the road surface. This technique had not been attempted before

and the machining rates were well beyond standard machining operations published in literature. Due to the

unknowns, a prototype cutting cell was developed that demonstrated the ability to machine markers as

proposed. This operation of the concept was confirmed through testing but some challenges that were

highlighted from testing are discussed. Lastly, a conceptual design was completed that contains features

needed to adapt the laboratory prototype into a mobile platform such as a truck.
