UDOT Construction Manual of Instruction

CONSTRUCTION MANUAL OF INSTRUCTION be provided to the inspection staff, including the materials lab and technicians. Mix designs in particular include important details such as mix proportions, admixtures, mixing and compaction temperatures, and approved sources. Concrete mix is required to meet the air content, temperature, slump, and strength requirements of the contract specifications, regardless of what the mix design indicates.

Materials Database The UDOT Materials Database (or Database) includes test reports and approved mix designs for pavement marking paint, reinforcing steel, asphalt materials, asphalt binder, and concrete. The Database also includes modules for test data input and report generation for certain materials and the creation of sample labels and witness forms, which allow either blank or project specific labels and witness forms to be produced.

Pavement Marking Paint REs are expected to use this module to verify pavement marking paint has been previously sampled by the Department and meets specifications. The RE should generate sample labels and witness forms for pavement marking paint from the Database and include test reports from this module in the project record.

Asphalt Materials This module can be used to access project specific mix design verification and approval letters. HMA and surfacing modules are used to generate acceptance reports showing specified incentive and disincentive amounts.

Asphalt Binder REs are expected to use this module to create sample IDs and generate sample labels and witness forms for binder samples. These samples are tested by the Department’s Central Materials Lab with the test results filed in the Database. REs should check the Database on a regular basis to verify asphalt binder samples meet the project specifications. Before contract completion, the RE should include the Database’s asphalt binder project report in the project record.
