| Abstract | In a coordinated effort with highway authorities and industry leaders, the Every Day Counts initiative serves as a catalyst to identify and promote cost effective innovations to bring about rapid change to increase safety of our nations highway system, decrease project delivery time, and protect our environment. The Safety EdgeSM concept is an example of one such initiative in which the edge of the road is beveled during construction for the purpose of helping drivers who migrate off the roadways to more easily return to the road without over correcting and running into the path of oncoming traffic or running off the other side of the roadway. This field report documents the observations made on the construction of the Safety EdgeSM on a two lane highway PCC overlay project on County Highway E34 (a.k.a. Fairview Road) in the vicinity of Fairview, Iowa. Details regarding the fabrication and performance of a custom device used to shape the Safety EdgeSM along with the shape and physical properties of the finished Safety EdgeSM are presented for the purpose of understanding what processes and techniques were most successful in forming the Safety EdgeSM. The findings from this overlay project and other similar ongoing projects form the basis for understanding the construction process and material performance necessary to bring this innovation into common highway practice and make our Nation’s highways safer. |
