Tests are performed employing unconsolidated undrained (UU) triaxial compression tests with pore pressure measurements under temperature controlled environmental conditions. A special triaxial compression test apparatus and an environmental control chamber were developed to achieve the objectives of this study. The change in the shear strength properties (angle of internal friction and cohesion) of the bituminous mixture at different testing temperatures (5oC, 20oC, 40oC, and 60oC), and asphalt cement contents are investigated according to sample preparation methods. A total of 72 test samples (4 and 6 inch diameters) are prepared to represent 4 temperatures, 3 asphalt content values, 3 different chamber pressures, and 2 types of sample preparation methods. Correlations are made with respect to mixture design parameters, including percent air voids (AV), voids in mineral aggregates (VMA), Hveem Stability Number (SN) and percent asphalt contents (AC). The analysis of the experimental data indicate the encountered deficiencies of the samples prepared by SGC, and confirm that the performance of asphalt pavements and the modeling of the flexible pavement as layered media can be represented by using shear strength parameters of the hot-mix-asphalt (HMA) mixture.
