Advanced BBR Test System

The Bending Beam Rheometer 3 (CRT-BBR3) has been designed to not only perform flexural tests on asphalt binder and similar specimens per ASTM D6648, AASHTO T313, and BS EN 14771, but the programmable test parameters make this system ideal for other tests as well.

The BBR3 offers a built-in computer. The 12 inch industrial strength touch-screen display is ideal for the newly designed software. Programmable test parameters allow the user to define a test and save those parameters for later testing. Predefined test parameters include the standard ASTM BBR test as well as the crack sealant test and the sliver test.

Programmable test parameters include: Deflection Plot, Load Plot, Bath Temperature, Stirrer Speed, Specimen size, Testing Times, Load, and Testing Company.

A complete BBR system consists of a fluid bath base unit, a built-in touch-screen computer, a three-point bend test frame, an external cooling unit, and a two calibration kits with carrying case.
