The TTI Asphalt Mixture Testing Laboratory has a full range of equipment needed for sample preparation and evaluation. The lab has standard capabilities for assessing asphalt mixture characteristics (such as stability and skid resistance) and asphalt cement properties (including viscosity, softening point, and flash point). TTI also has the capabilities for performing the SHRP binder specification tests: bending beam rheometer, dynamic shear rheometer, and Brookfield viscosity. Complete molding and test equipment for Hveem and Marshall testing are available. In addition, a computer-controlled ductility machine enables ductility to be assessed as a function of either rate or force.
