Effects of Laboratory Compacted Asphalt Mixtures Air-Void Variations on Fracture Properties at Low Temperatures

Asphalt mixtures contain several constituents, among which air void content has a significant effect on pavement performance. In this research, the impact of laboratory compaction air-void variations for asphalt mixtures was investigated on asphalt-mixture fracture energy and peak load, as two primary outcomes of the disk-shaped compact tension test. Two groups of asphalt mixtures with air void contents of 7 ± 1.0 % were selected, and...
