Direct Estimation of Air Void Content from Gyratory Compaction History
Abstract: A computational approach is offered and explored for estimating the air void content of asphalt mixtures densified in the Superpave gyratory compactor. It entails fitting a sigmoidal function to the compaction history records of specimen height vs. gyration level. The compaction progress is then extrapolated mathematically to infinite number of gyrations for which the air void content is theoretically zero. The fitted densification curve is then used to estimate the …
