617.4 Laboratory Testing Guidelines for Sec 617
This article establishes procedures for Laboratory testing and reporting of concrete cylinders which represent material used in concrete median barriers. Refer to Sec 617 for MoDOT’s specifications.
617.4.1 Procedure
Concrete cylinders shall be tested for compressive strength according to AASHTO T22. Test results and calculations shall be recorded through AASHTOWARE Project (AWP).
617.4.2 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. The notation "Specimens submitted for compressive strength at the age indicated" should be included in the sample record remarks. Test results shall be reported on the appropriate templates under the Tests tab.
