List of Laboratory Equipment

We have excellent testing equipment that may assist you in your next project. We also have experienced personnel who get the most out of this equipment. You'll find descriptions of these resources in these pages.

 
ASPHALT FACILITIES
The equipment list below identifies current, state-of-the-art compression and tension machines available in the laboratory. The machines have load ranges from a few hundred pounds to one million pounds providing a capability to test a wide variety of materials and structures.
 
Machine Name Function
Dynamic Shear Rheometer (DSR) Measures rheological properties, complex shear modulus
(stiffness or resistance) & phase angle of asphalt cements.
Bending Beam Rheometer (BBR) Tests the deflection of a beam of asphalt from the stiffness modulus & log slope of the creep curve.
Rolling Thin Film Oven (RTFO) Tests short term aging to simulate construction aging of asphalt binders.
Bitumen Bond Strength (BBS) Measures asphalt binder adhesion and cohesion properties with and without moisture conditioning.
Pressure Aging Vessel (PAV) Simulates in-service aging of asphalt binders.
Rotational Viscometer Outlines determination of high temperature viscosity of asphalt
binders (unaged).
Gyratory Compactor Makes asphalt sample for SuperpaveTUpavement analysis.
Impedance Tube Measures noise dissipation and reflection in compacted asphalt mixture samples and cores.
Laser Profilometer Measures the surface macro textures and micro textures of asphalt mixtures.
Chip Seal Sweep Test Evaluates asphalt emulsion chip retention of chip seal applications.
Glass Transition Dilatometric Device Measures the glass transition temperature and coefficients of thermal expansion and contraction for asphalt binders and mastics.
Axial Testing System with Environmental Chamber The device allows for temperature controlled testing of asphalt mixtures in various loading modes such as indirect tension, repeated creep and asphalt beam fatigue test.
