To identify which pavement marking materials work best on asphalt surfaces in the Midwest, the Joint Transportation Research Program—a collaboration between Indiana DOT and Purdue University—developed and assessed a variety of new testing methods and protocols.
Designed to assess a range of properties, such as elasticity, durability and bond to the pavement, the tests can help maintenance crews identify tapes and thermoplastics that are likely to adhere well to pavements and withstand extreme temperature fluctuations.
