Laboratory Performance Evaluation of SMA in Oklahoma

The objective of this study is to determine if SMA mixtures have better rutting performance than S-4 mixes made with the same PG grade of binder. Different SMA and S-4 mixtures were collected from different parts of Oklahoma. All mixtures were made with PG 76-28 asphalt cement. To evaluate the performance properties of the mixtures, samples were made and tested for Hamburg rutting resistance using the Hamburg rut tester. Generally, SMA mixes have been shown to perform better with respect to rutting resistance than S-4 mixes. SMA mixes showed lower average rut depth than S-4 mixes.
