Materials and Research

Contractors must use preapproved water-based marking paint from the list below. The information below must be submitted by the pavement marking paint manufacturer for material lots to be included on the preapproval list. Failure to fully supply the information or failure of a material sample will result in rejection of the material.

NTPEP Testing

Submit paint to the National Transportation Product Evaluation Program (NTPEP). Include a reference to the specific NTPEP Test Deck to which the paint formulation was applied, including NTPEP identification numbers and report numbers.

Provide test results from laboratory testing and field evaluation from a Northern NTPEP test deck from within the previous 6 years.

October 1, 2020: Provide test results from laboratory testing and field evaluation from a Northern NTPEP Test Deck from within the previous 4 years.

Laboratory Testing and Sample Submission

The marking manufacturer must perform testing on each lot of material intended for a NDDOT project. Submit test results for each lot of material that show compliance with the marking material specification (Section 880, “Pavement Markings” of the NDDOT Standard Specifications for Road and Bridge Construction). Obtain two, 1-pint samples of paint from each lot and use epoxy lined cans for sampling and shipping. Obtain the samples in the presence of the NDDOT’s Engineering representative. Submit the samples to the NDDOT Materials and Research Division at least 30 days prior to the scheduled use of the material.
