Text of Abstract
Temporary pavement markings (TPMs) are a critical safety tool for both road workers and drivers during construction on active roadways. TPMs are viscoelastic pressure sensitive adhesives with a reflective layer embedded in them to increase visibility. Drivers rely on TPMs to safely navigate work zones, especially at night or during inclement weather. However, premature failure of these TPM tapes is a rampant problem, particularly in extreme hot and cold climates. To better characterize the adhesive performance of these TPM tapes, a new testing methodology has been developed to perform peel testing of TPM tapes from pavement surfaces. Pressure sensitive adhesive tapes are commonly assessed using 90º peel adhesion tests to determine the work of detachment. However, typical 90º peel test fixtures translate the substrate as the force is applied, precluding roadway testing. Our novel methodology allows for peel testing of PSA tapes from immobile substrates through a custom peeling fixture. We have performed tape rate and width qualification experiments to validate the methodology. Additionally, the ability of the fixture to peel various types of tapes as well as tapes from several immovable substrates is demonstrated. Finally, dynamic mechanical analysis of both the tape backing and adhesive layers is utilized to relate critical materials transition temperature to peel performance for several brands of TPM tapes. The modular nature of the design allows for field testing for temporary pavement markings.
