Examine Dual-Component Pavement Marking Alternatives

Pavement marking products have changed significantly over the past 15 years, to the extent that the current ADOT specifications (ADOT 709 Spec) have not kept up with industry advancements. New products are available that meet revised environmental regulations and offer improved performance and application options. The study surveyed state agencies with climate conditions similar to regions within Arizona to gather data and information regarding their experiences with pavement marking performance and costs. In addition to the state agency-based data collection effort, there was a search of the National Transportation Product Evaluation Program (NTPEP) DataMine for relevant pavement marking performance data. Results from the evaluation of data from the research will provide technical support for updating the 709 Specification and utilization by construction contractors and ADOT maintenance crews.
