This article establishes procedures for Laboratory testing and reporting samples of precast concrete flared end sections. Refer to Sec 1032 for MoDOT's specifications.

1032.3.1 Procedure

Tests consist of compression and absorption.

Compression Test. Samples may consist of two standard concrete cylinders made in accordance with AASHTO R100 or one core drilled from the wall of the section in accordance with AASHTO T280.

a) Concrete cylinders shall be tested in accordance with AASHTO T22. Test results and calculations shall be recorded through AASHTOWARE Project (AWP).
b) Drilled cores shall be tested in accordance with AASHTO T280. Test results and calculations shall be recorded through AWP.

Absorption Test. Samples shall be tested in accordance with AASHTO T280. Test results and calculations shall be recorded through AWP.

1032.3.2 Sample Record

All sample records shall be completed in AASHTOWARE Project (AWP), as described in AWP MA Sample Record, General. Test results shall be reported on the appropriate templates under the Tests tab. Compression test results for concrete cylinders shall include the notation in remarks, "Specimens submitted for compressive strength at the age indicated." Compression test results for concrete cores shall include the notation in remarks, "Sample submitted for the determinations indicated." Absorption test results for concrete cores or pieces from the wall of the section shall indicate acceptance, qualified acceptance, or rejection. Appropriate remarks, as described in in EPG 106.20 Reporting, are to be included in the remarks to clarify conditions of acceptance or rejection.
