Two Point Trapezoidal Bending Beam Machine

Optimization of the setting up time with intelligent software and accurate temperature control with an integrated temperature cabinet. Bending tests are widely used for measuring the stiffness modulus and assessing the fatigue resistance of asphaltic paving materials. The two-point bending test on trapezoidal specimens is, arguably, the most repeatable and reproducible bending test method detailed in the revelant EN 12697 standards. In this test, the specimen is mounted as a vertical cantilever. The base is fixed and the top is moved sinusoidally with a constant displacement amplitude. The trapezoidal specimens are tested simultaneously and stiffness are subjected to a constant strain amplitude at a selected frequency and temperature until the stiffness modulus decreases to a user-selected target level (normally 50 percent of its initial value).
