Abstract
A loaded wheel tester for testing asphalt mixtures comprises a loaded wheel tester having additional means for attachment to specimens under test to provide a measurement of tensile strain and for attachment between a frame of the loaded wheel tester and the loaded wheel to determine position of the loaded wheel over time. Output results demonstrate that viscoelastic and fatigue properties of asphalt mixtures are obtained in equivalent or improved format using a modified loaded wheel tester when compared with known pavement test apparatus and methods.
