SPR 12-439 Safety Edge Performance

Grants and Contracts Details


This research will observe asphalt construction utilizing several different Safety Edge technologies, and monitor multiple aspects of construction and performance related to each technology. These observations will provide Kentucky Transportation Cabinet personnel the necessary information for decision-making regarding appropriate changes to asphalt construction specifications. The Safety Edge is a paving detail that consolidates the pavement edge into a30-degree angle to mitigate pavement-edge drop-offs, offering drivers that leave the roadway a safe transition back to the road. However, even the smallest change in construction can have significant ramifications throughout the construction process. The Kentucky Transportation Cabinet has solicited the Kentucky Transportation Center to consider the effects of incorporating the Safety Edge in future construction. Consideration would attempt to quantify increases in construction costs and improvements in roadway safety. In addition, in situ properties such as density and permeability would be evaluated in order to develop methods for control and acceptance of the finished product.
