UNIAXIAL EXPERIMENTS ON IDEALIZED ASPHALT MIXES

This paper contains details of uniaxial compression experiments on various idealized asphalt mixes with volume fractions of aggregate ranging from 40% to 85%. The compression experiments were performed over a wide range of temperatures, stresses, and strain rates. The steady-state axial behavior of the mixes had the same form as that of bitumen with the aggregate acting as a stiffener. However, the mixes with high volume fractions of aggregate dilated under a uniaxial compressive stress. The experimental results were compared with theoretical predictions of a modified version of Hashin's composite sphere model. Good agreement was observed.
