Research Abstract

A quasi-tensile test for bituminous binder is proposed by using the force ductility test. This test has good reproducibility and the test results follow the time-temperature conversion law. The maximum stress, the modulus, and the energy necessary to break point of the polymer modified asphalt obtained from this test show good correlations with the mechanical properties of asphalt mixtures obtained from the indirect tensile test.
