Evaluation of Materials for Asphalt Mixture Performance, Semi-Circular Bend Field Material

The data contained herein is part of a study conducted with support from the Utah Department of Transportation.  In the study, seven asphalt mixtures from across the state of Utah were collected at the plant (prior to delivery) and at laydown (prior to compaction).  The mixtures were sealed in metal containers and brought to three different laboratories where the asphalt mixtures were compacted using a Superpave gyratory compactor into cylinders.  Each cylinder was cut using a masonry saw to create semi-circular samples with a notch in the middle based on the specification from AASHTO T124-16.  The samples were tested following the procedures outlined in the specification with some exceptions where the loading rate was changed.  The results were used to developed specification limits.
