Suite of Tests
The heart of this research is the suite of tests that will be developed and recommended as a procedure to ensure durable pavements. Tests are needed to address the characteristics of concrete as they relate to the three phases in the design and construction process.
A group of tests will be developed that addresses a project's phases of design, verification, and quality control/quality assurance:
- During the design phase, laboratory tests will characterize the constituents, check for compatibility, and ensure an optimum design. .
- During the verification phase immediately prior to the beginning of construction, tests will ensure that the materials are similar enough to those used in the design to result in a long-lived pavement.
- During the quality control/quality assurance phase, field tests will ensure that consistent, quality concrete pavement is being constructed.
The researchers are developing a matrix to organize the tests. The matrix will change as the project continues and as more tests are discovered through the data collection process and information from others.
The tests in the matrix will be evaluated for their effectiveness in predicting
and determining material and concrete characteristics. Test procedure modifications
may be proposed. New tests may be developed, if needed.
