A list of qualified Type 1 and Type 2 preformed marking tape will be maintained by Construction and Materials. The list is shown in [http://www.modot.mo.gov/business/materials/pdf/vol_1/FS1048T1.pdf Qualified Type 1 and Type 2 reformed Marking Tape]. To obtain prequalification of any Type 1 or Type 2 preformed marking tape, the manufacturer must submit material and application specifications, a 20 ft. (6 m) sample of the tape, and a history of satisfactory use as a pavement marking tape to Construction and Materials for testing and evaluation. The types and widths of marking submitted must be as directed by Construction and Materials. Following the testing and evaluation, satisfactory products will be placed on a list of qualified marking tapes.
+
A list of qualified durable intersection marking materials will be maintained by Construction and Materials. To obtain prequalification of any durable intersection marking materials, the manufacturer must submit AASHTO NTPEP test deck data from a northern test deck to Construction and Materials for evaluation. Following the evaluation of the data, one year of field evaluation in Missouri may be required. Once all evaluations are complete and satisfactory, the product will be placed on a list of durable intersection marking.

Contents

1048.1 Apparatus

(a) Micrometer or vernier caliper capable of measuring to 0.0001 in. (0.00254 mm) and accurate to within at least 0.001 in. (0.0254 mm).

(b) Rule with suitable graduations to accurately measure the material to be inspected.

(c) One-quart (1 L) friction top cans that are clean, dry and free of all contaminants.

1048.2 Procedure

1048.2.1 Durable Intersection Marking Materials

1048.2.1.1 Qualified List

A list of qualified durable intersection marking materials will be maintained by Construction and Materials. To obtain prequalification of any durable intersection marking materials, the manufacturer must submit AASHTO NTPEP test deck data from a northern test deck to Construction and Materials for evaluation. Following the evaluation of the data, one year of field evaluation in Missouri may be required. Once all evaluations are complete and satisfactory, the product will be placed on a list of durable intersection marking.

1048.2.1.2 Certification

For acceptance on the project, the contractor must furnish a manufacturer's certification stating the manufacturer and brand name, and certifying that the material furnished is of the same composition as originally qualified.

1048.2.1.3 Inspection

Preformed products can be inspected to assure it is in good condition, free of cracks and with straight and unbroken edges before it is applied as well as inspecting adhesion and alignment. Liquid product can be inspected during and after application to assure proper alignment, bead application and embedment as well as general appearance.

1048.2.1.4 Sampling

Take samples any time the inspector considers sampling necessary. For preformed material, the sample should consist of one piece, full width, not less than 20 ft. (6 m) long. If questions arise with the liquid products, sample of the product pre-application would be taken. The sample should be submitted to the Laboratory accompanied by a properly completed SiteManager record showing the manufacturer's name, the brand name and designation of the material, lot number, and net quantity.

1048.2.1.5 Sample Record

Report durable intersection marking materials through SiteManager. Retain the manufacturer's certification in the district office.
