This article establishes procedures for testing and reporting Laboratory samples of bolts, nuts, washers, and polyurethane foam used in highway lighting. Refer to Sec 901 for MoDOT’s specifications.
901.18.1 Procedure
Bolts, Nuts, and Washers
Chemical tests consisting of mass of coating shall be determined according to AASHTO M232. Original test data and calculations shall be recorded in Laboratory workbooks. Test results shall then be recorded through AASHTOWARE Project (AWP).
Physical tests shall be conducted according to EPG 712.3.2.2 Physical Tests - Bolts and Nuts. Test results and calculations shall be recorded through AWP.
Polyurethane Foam
Tests on samples of polyurethane foam shall be conducted in accordance with the following methods:
- (a) Compressive Strength - ASTM D1621
- (b) Density - ASTM D1622
Test results and calculations shall be recorded through AWP.
901.18.2 Sample Record
The sample record shall be completed in AASHTOWARE Project (AWP), as described in AWP MA Sample Record, General, and shall indicate acceptance, qualified acceptance or rejection. Appropriate remarks, as described in EPG 106.20 Reporting, are to be included in the report to clarify conditions of acceptance or rejection. Test results shall be reported on the appropriate templates under the Tests tab.
