Before traffic marking paint can be approved for use it must be submitted for evaluation to ensure that it conforms to federal and/or state specifications. Testing includes the application of transverse traffic marking to test decks exposed to a high volume of vehicular traffic and the elements, as part of the National Transportation Product Evaluation Program (NTPEP), and may last as long as three years.
In an effort to reduce the time and cost associated with developing higher performance traffic marking paints, abrasion resistance has been proposed as an accelerated method for evaluating the durability of traffic markings. It is a simple and inexpensive technique which yields highly reproducible results in a short period of time. These results correlate well with available NTPEP t
