Abstract
The principle and procedures of partial triaxial compression test (PTCT) was introduced. The appropriate diameter and height of specimen and platen were determined for PTCT requirement. Three types of mixtures were tested by PTCT at a temperature of 60°C. Stress–strain results indicate that the response of asphalt mixtures to various test conditions by PTCT is in accordance with that of typical triaxial compression tests. Also, both PTCT and traditional triaxial compression test represent the similar deformation characteristics of asphalt mixtures. The PTCT inherits many advantages possessed by the triaxial test, and is easier to be carried out considering the simplicity of experimental equipment, specimen preparation, and test operation.
