This article establishes procedures for Laboratory testing and reporting samples of paint and paint materials. Refer to Sec 1045 for MoDOT’s specifications.

1045.6.1 Procedure

1045.6.1.1 Pigment and Vehicle Constituents

Test these materials in accordance with the following methods:

Inorganic Zinc Silicate Pigment, Metallic Zinc, percent - ASTM D521
Total Zinc, percent - ASTM D3280.
Inorganic Zinc Silicate Vehicle- ASTM D1644, Method A.

1045.6.1.2 Mixed Paint

The following paints shall be tested according to the methods shown for each material.

a) High Solids Inorganic Zinc Silicate Paint. This material is to be tested according to Sec 1045.2.
b) Intermediate Coat - High Solids Epoxy System G Finish Coat - Polyurethane System G.

All test data and calculations are to be recorded in Laboratory workbooks. Test results are then to be recorded through SiteManager.

1045.6.2 Sample Record

The sample record shall be completed in SiteManager, as described in Automation Section 3510, and shall indicate acceptance, qualified acceptance, or rejection. Appropriate remarks, as described in EPG 106.20 Reporting, are to be included in the remarks to clarify conditions of acceptance or rejection. Test results shall be reported on the appropriate templates under the Tests tab.
