Bending Beam Rheometer, 230 V/50-60/1 Ph

Apparatus used to perform flexural tests on asphalt binder, bitumen and similar specimens A constant force is applied to a specimen in a chilled bath in order to derive specific rates of deformation at various temperatures. Part of the original Superpave requirements.

An air bearing system to assures reliable loading with accurate and repeatable results. A linear variable displacement transducer (LVDT) with a range of 6.35mm and accuracy to ±2µm measures deflection. The stainless steel three-point bend apparatus is easily removed and reinstalled in the base unit for convenient sample preparation and loading.

A fluid bath controls temperature of the Ethylene Glycol/Water/Methanol mixture down to -40°C (-40°F). Process temperature is controlled by two independent platinum RTD temperature transducers to maintain stability. Fully complies with ASTM/AASHTO requirements.

A source of clean, dry, compressed air at 50 PSIG minimum must be provided by the user. Models come with five aluminum specimen molds with mylar strips, a Calibration Kit with required weights, and Confidence Beam. Calibrated test weights and a certified LVDT NIST-traceable standard are also provided.

Meets ASTM P245, D6648, EN 933-8, AASHTO T313-02.
