Abstract:

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. Comparison of fracture properties from the SCB test and fatigue beam test (FBT) was conducted. The SCB Jc values for PG64-10 and PG58-22 mixtures on dry and wet conditions were determined. An FBT was performed on PG64-10 and PG58-28 mixtures in dry and wet conditions. The SCB Jc and FBT Nf indicated better fracture properties for the dry mixtures compared to wet mixtures. In general, the SCB Jc and the FBT Nf had similar ranking of both mixtures at dry and wet conditions. The FBT Nf had higher variability, %CV (16.5 – 48.9%), compared to SCB Jc, %CV (0 – 33.2%). The SCB test has great potential as a QA/QC test of fracture properties of asphalt mixtures.
