Beam Fatigue Test
The GCTS Beam Fatigue Testing System was designed to test the fatigue life of a beam of Hot Mix Asphalt. These tests are computer-controlled and can be performed under either constant stress or constant strain conditions. This system does not need to be used with any other system to perform tests, as this compact system is completely "stand-alone."
The Beam Fatigue System features:
ASTM D7460 Standard Test Method for Determining Fatigue Failure of Compacted Asphalt Concrete Subjected to Repeated Flexural Bending
AASHTO T321 Standard Method for Determining the Fatigue Life of Compacted Asphalt Mixtures Subjected to Repeated Flexural Bending
AASHTO PP3 Standard Practice for Preparing Hot Mix Asphalt (HMA) Specimens by Means of the Rolling Wheel Compactor
The GCTS Beam Fatigue Testing System can be used to determine the fatigue life of a layer of Hot Mix Asphalt. This system is controlled by the advanced software developed by GCTS and is a completely "turn-key" system. The software automatically calculates multiple fatigue life parameters, including initial stiffness, maximum tensile stress and strain, flexural stiffness, phase angle, dissipated energy per cycles, and number of cycles to failure.
