Introduction
This manual describes the CANNON Thermoelectric Bending Beam Rheometer and the procedures
for obtaining test data. The Bending Beam Rheometer is used to make rapid determinations of the
flexural-creep stiffness of asphalt binders over a temperature range of 0 °C to -36 °C.
The user of this manual and instrument should have some experience in the handling and testing of
asphalt binders and should be familiar with the operation of the Windows® operating system.
Procedural Overview
A small beam of asphalt is prepared and placed horizontally on two supports which are submerged
in a cold alcohol solution. A load is applied at the center of the beam and the deflection of the beam
is recorded over a time span of four minutes. From this data, the stiffness modulus and the log slope
of the creep curve at test temperature are calculated.
