This article establishes procedures for Laboratory testing and reporting samples of material to be used in joints for concrete structures, concrete pavement, base, median, median strip, paved approach, curb, curb and gutter, gutter and sidewalk. Refer to Sec 1057 for MoDOT's specifications.

1057.4.1 Procedure

1057.4.1.1 Dowel Bars

All dowel bars shall be tested for tensile and bending properties of plain rounds in accordance with AASHTO M31 Billet Steel; AASHTO M42, Rail Steel; or AASHTO M53, Axle Steel. Dowel bars, which are not epoxy coated shall be tested for mass variations. Test results and calculations shall be recorded through SiteManager.

1057.4.1.2 Tie Bars

Tie bars shall be tested in accordance with Reinforcing Steel for Concrete - Billet-Steel Deformed Bars. Tie bars, which are to be bent and straightened, shall be tested in accordance with 1036.7.1.1.1 Uncoated Billet-Steel and shall be grade 300 mPa (40). Test results and calculations shall be recorded through SiteManager.

1057.4.1.3 Concrete Joint Sealer, Hot-Poured Elastic Type

Samples shall be tested in accordance with Specification Sec 1057.1.3 for flow, penetration, resilience, bond, and Asphalt Compatibility. These tests will be completed on every fourth sample from a producer. If any of the tests fail, the producer's next sample will also be tested for the four properties and Asphalt Compatibility. The other samples not subjected to full testing will be tested for flow, penetration and resilience only to determine acceptance. Test results and calculations shall be recorded in Laboratory workbooks or on Work Form "Hot Pour Joint Sealer". Test results shall then be recorded through SiteManager.

1057.4.1.4 Preformed Fiber Expansion Joint Filler

Samples shall be tested for thickness, compression, recovery, extrusion, density, water absorption, and bitumen content in accordance with AASHTO M213. Test results and calculations shall be recorded through SiteManager. Bitumen content shall be originally recorded in a Laboratory workbook.

1057.4.1.5 Copper Sheeting

Copper sheeting for flashing shall be tested in accordance with the following methods:

Percent Copper - ASTM E53
Thickness and Elongation - AASHTO T68
Bend Properties - Specification Sec 1057.2.3

Test results and calculations shall be recorded through SiteManager. Percent copper shall be originally recorded in a Laboratory workbook.

1057.4.1.6 Sponge Rubber

Sponge rubber compound expansion and partition joint filler shall be tested for thickness, compression, recovery, extrusion, and density in accordance with Specification Sec 1057.2.4. Test results and calculations shall be recorded through SiteManager.

1057.4.1.7 Plastic Joint Compound

Plastic joint compound for vitrified clay and concrete pipe shall be tested in accordance with the following methods:

Percent Bitumen soluble in trichloroethylene and percent ash - AASHTO T44
Penetration - AASHTO T187

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

1057.4.2 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.
