Abstract:

This study conducted before/after safety evaluations of projects involving the installation of rolled-in CSRS on rural and urban freeways. During resurfacing and shoulder rehabilitation projects, rolled-in CSRS are formed by a roller that leaves grooves during the compaction of the asphalt on the shoulder. In recent years, most CSRS installations have been of the milled type. Field tests conducted by Virginia Department of Transportation for pavement roughness and sound levels on various typical rumble strips found that the milled type was 12.6 times and 3.35 times greater in the pavement roughness index and sound levels, respectively, than the rolled type.
