Re-evaluating Asphalt Rutting Test for Balanced Mix Design and Quality Assurance Acceptance
In general, Ohio doesn't have a rutting problem with asphalt mixes, but with the push to move to Balanced Mix Design (BMD) becoming prevalent, rutting tests will be expected to be used more frequently for most mix designs. BMD creates the opportunity to increase the use of Reclaimed Asphalt Pavement (RAP) and the use of specialized additives. With specialized additives, rut-prone mixes may appear. A test that is capable of screening asphalt mixes during the mix design phase, and a quality assurance (QA) test employed during the production phase to verify that mixes are not susceptible to rutting are needed. The goal of this research is to support Ohio Department of Transportation's (ODOT's) transition towards BMD by updating rutting test protocols to methods that can be used during mix design and in QA. These projects objectives include determination of rutting test(s) to use for BMD and QA acceptance and determination of operating parameters and failure criteria for rutting tests based on field performance.
