RHEOLOGICAL PROPERTIES OF ROAD MATERIALS AND THEIR EFFECT ON THE BEHAVIOR OF A PAVEMENT SECTION TESTED IN A CLIMATE CONTROLLED, LINEAR TRACK ROAD TESTING MACHINE

A new three-point bending machine has been used to determine the rheological properties of asphalt mixes. The stiffness of mixes is shown to be both dependent on temperature, frequency and strain amplitude. Relatively large beams can be tested in virtue of a mechanical lever arm system which is able to utilize the capacity of the vibrator employed to great advantage. The accuracy and ease of measurements are augmented by the use of a sophisticated electrical system for determining the forces and deflections without phase lag problems. A newly constructed, linear track road testing machine has investigated the performance of a full-depth asphalt pavement section. Fatigue tests under two moving wheel loads of, respectively, 20 kN and 30 kN were conducted in the road testing machine.
