Evaluation of Stamark Brand Bisymmetric 1.75 Grade Pavement Marking Tape

The objective of this project was to evaluate the performance of Stamark Brand Bisymmetric 1.75 Grade pavement Marking Tape (Series 320) on a large-scale installation on Interstate 24 in McCracken County. The evaluation consisted of periodic inspection of the tape to determine its durability, appearance, and reflectivity. The tape has demonstrated good performance after two years in service. No durability problems were noted. While the appearance of the tape was not as bright as a typical traffic paint, it was adequate. The tape has maintained a high level of reflectivity. The performance of the material would potentially warrant additional use as longitudinal marking on moderate volume roadways. However, the cost of the tape must be considered in determining its use
