This article establishes procedures for testing and reporting of preformed pavement marking tapes, thermoplastic pavement marking material, waterborne traffic marking paint, acrylic copolymer traffic marking paint, epoxy traffic marking material, snowplowable raised pavement markers, temporary raised pavement markers and drop-on glass beads. Refer to Sec 1048 for MoDOT’s specifications.

1048.3.1 Apparatus

The apparatus is designated in the test methods referred to for testing the particular type of material.

1048.3.2 Procedure

1048.3.2.1 Preformed Marking Tapes

1048.3.2.1.1 Reflectance

Test all types of preformed marking tape for compliance with the reflectance requirements of Sec 1048 by MoDOT Test Method TM-8.

1048.3.2.1.2 Physical Requirements

Inspect all types of pavement marking tape to determine compliance with the requirements of Sec 1048 for dimensions, flexibility and suitability of adhesive.

Documentation. Evaluate the documentation furnished by the manufacturer for compliance with Sec 1048.

In the case of preformed removable pavement marking tape, Construction and Materials will request Traffic by letter to apply test lines of the tape and to monitor and report results to Materials. The letter will request:

(1) Four 12 ft. (3.6 m) long test lines, of each color, be applied transversely to both concrete and asphaltic concrete pavements.
(2) The tapes be applied and removed within the temperature range recommended by the tape manufacturer.
(3) One tape of each color be removed manually at time of installation and at 30-day intervals until all test lines are removed.
(4) The tapes be evaluated for ease and completeness of removal, bead retention, durability and whether the tape left an objectionable or misleading image after removal.

1048.3.2.2 Thermoplastic Pavement Marking Material

Test thermoplastic pavement marking material for compliance with Sec 1048 using the applicable methods set forth in AASHTO M 249 and AASHTO T 250.

1048.3.2.3 Drop-on Glass Beads

Test drop-on glass beads for compliance with Sec 1048. The test methods are those set forth in AASHTO M 247, with the exception of the silica (SiO2) content. The silica content is determined by ASTM C 169, Procedure for Referee Analysis.

1048.3.2.4 Waterborne Traffic Marking Paint

Test waterborne traffic marking paint for compliance with Sec 1048. The test methods are set forth in Sec 1048.

1048.3.2.5 Acrylic Copolymer Traffic Marking Paint

Test acrylic copolymer traffic marking paint for compliance with Sec 1048. The test methods are set forth in Sec 1048.

1048.3.2.6 Epoxy Traffic Marking Paint

1048.3.6.1 Test epoxy traffic marking paint for compliance with Sec 1048. The test methods are set forth in Sec 1048.

1048.3.2.7 Snowplowable Raised Pavement Markers

Snowplowable raised pavement markers are no longer installed in MoDOT projects. Rehabilitation is to comply with JSP-07-07 Snowplowable Raised Pavement Marker Rehabilitation or Removal.

1048.3.2.8 Temporary Raised Pavement Markers

Test temporary raised pavement markers for compliance with Sec 1048. Dimensional requirements are set forth in Sec 1048.

1048.3.3 Sample Report

Complete the sample record in AASHTOWARE Project (AWP), as described in AWP MA Sample Record, General, and indicate acceptance, qualified acceptance or rejection. Include appropriate remarks, as described in EPG 106.20 Reporting, in the remarks to clarify conditions of acceptance or rejection. Report test results on the appropriate templates under the Tests tab.
