The mixture testing laboratory is the main research laboratory for advanced material characterization testing of asphalt mixtures and unbound materials. Several state of the art servohydraulic closed loop systems are housed in this section of the laboratory. These include three 25 kN and one 100 kN Universal Testing machine (Industrial Process Control – IPC) for uniaxial and triaxial testing of paving materials. All three of these systems have environmental chambers for temperature conditioning. In addition, an Instron system dedicated for Indirect Tensile testing and an SBEL system that has triaxial capabilities for unbound material are also available.
