Abstract:

Four projects were built over two construction seasons using special devices attached to the paving machine that produces a 30 degree slope on the outside pavement edge instead of the near vertical drop-off common with conventional paving equipment. This pavement edge treatment allows vehicles that leave the roadway a gentler slope to navigate when remounting the pavement. The projects used four types of devices; (1) the TransTech Shoulder Wedge MakerTM, (2) the Advant-EdgeTM, (3) the Carlson Safety Edge End Gate, and (4) a contractor built device. All of the devices were able to produce a finished pavement slope that was close to the 30 degree angle recommended by FHWA. The cost of adding the pavement edge treatment was minimal for both the Contractor and WSDOT. The safety benefits of the pavement edge treatment could not be measured due to the absence of a statistically significant number of crashes at the test locations.
