Fatigue cracking is a primary distress in asphalt due to repetitive stresses and strains caused by traffic. The main objective of this study is to investigate the use of the semi-circular bend (SCB) test as a quality assurance/quality control (QA/QC) measure for field construction.
The SCB test parameters were determined using two methods, the first of which was cross-head movement (CHM), and the second was non-contact camera. In SCB CHM method the specimens were loaded monotonically until fracture under a constant cross-head deformation, while in none-contact camera method a camera was fixed in front of the SCB specimen to measure the crack length. In addition beam-fatigue test (BFT) was conducted according to AASHTO T-321 on the same mixtures.
A comprehensive comparison between the test results is performed. The results of this study indicate that the SCB test has a great potential as a QA/QC test of fracture properties of asphalt mixtures.
