The improved Bending Beam Rheometer 3 (CRT-BBR3) has been designed to perform flexural tests on asphalt binder and similar specimens per AASHTO T 313, AASHTO TP 87, ASTM D6648, and BS EN 14771 specifications as part of the PG grading system according to Superpave. The BBR3 is the first of its kind to offer an internal computer system incorporating touch screen technology.
Each BBR consists of a fluid bath base with a built-in touchscreen computer, load frame, external refrigeration unit, and a calibration kit with carrying case. Used in part to determine a sample’s critical cracking temperature and low temperature PG grade, the BBR’s -40⁰C to 25⁰C temperature range is efficiently calculated by a platinum RTD measuring device. The 500g load cell and changeable specimen supports easily transition the BBR3 for crack sealant testing.
Designed to be user friendly and efficient, the BBR3 allows operators to enter a multitude of customisable test parameters. A built-in Ethernet connection allows users to monitor their equipment remotely using a tablet, smartphone, or other mobile device.
