Abstract

"The Illinois Department of Transportation (IDOT) was appointed to chair an American Association of State Highway and Transportation Officials’ (AASHTO) effort to develop a specification that will simplify and improve how sign sheeting materials will be specified for state DOTs. At the same time, ASTM began efforts to modify their specifications which over the years have expanded to the point that each type that is specified is unique to a single producer. To address the true differences in the performance of these materials TxDOT and TTI (Texas Transportation Institute) conducted a sign sheeting research demonstration, ""Standard Specification for Retroreflective Sheeting for Traffic Control,"" held on May 21-22, 2009, in College Station, Texas. The two entities hosted the event in which manufacturers, industry, and end users joined forces to attempt to resolve questions regarding how drivers perceive retroreflective sign materials. This report contains the proceedings of the field trip experience from the May demonstration in Texas and summarizes the discussions leading to a final draft specification (7/25/09) that was distributed to the AASHTO Subcommittee on Materials Tech Section 4d Sign Sheeting Task Force. This effort led to a new AASHTO Standard Specification for Retroreflective Sheeting for Traffic Control (M 268-09)."
