Rational Test Methods for Predicting Permanent Deformation in Asphalt Concrete Pavement
In the report the existing test methods are reviewed to understand the mechanisms of permanent deformation in asphalt concrete. Based upon this information, the uniaxial compression creep/recovery tests are designed to characterize the mechanical behavior of the asphalt concrete. The characteristics of permanent strains are analyzed as inferred from test results. It is shown that the separation of the strains into the time independent elastic and plastic strains and the time dependent viscoelastic strains requires tests with various unloading times. The analysis is illustrated with results of a series of tests on one asphalt concrete mixture.
