Federal Highway AdministrationUS Transportation CollectionThe Oregon Department of Transportation (ODOT) requires performance and durability testing of all pavement marking materials before they can be applied on construction projects on state highways. Manufacturers apply materials on a two-year test deck where the product is evaluated regularly until a determination can be made regarding the suitability of the marking material. If it is determined that the material is suitable, it is included on the Qualified Products List (QPL). The testing and evaluation on ODOT test decks are limited to measuring the thickness of the marking material; assessing dry weather retroreflectivity; and subjective evaluations of appearance and durability. It was determined that a review of pavement marking testing procedures especially those followed in states with climatic conditions similar to Oregon could be useful. The research project includes recommendations to enhance the pavement marking testing and selection process. The recommendations relate to application procedures, monitoring and evaluation, and final selection of products. Proposed minimum retroreflectivity requirements are discussed
