Improving asphalt pavements

Disc-Shaped Compact Tension fracture energy is discussed in Disc Shaped Compact Tension (DCT) Specifications Development for Asphalt Pavement , a report from the Minnesota Department of Transportation. This report refines the DCT fracture energy testing procedure, identifies needed adjustments in asphalt mixture to increase fracture energy, determines the suitability of DCT-test-based parameters as indicators of reflective cracking, and proposes threshold values to lower the potential for premature refle...
