Disc Shaped Compact Tension (DCT) Specifications Development for Asphalt Pavement

Status:  Active
Project Start Date:  07/08/2014


The objectives of the research are to: Assess DCT testing variability through round robin testing among selected consultants and MnDOT Verify / establish fracture energy criterion for asphalt concrete construction acceptance. This includes reviewing existing literature and data from MnDOT and other agencies Develop DCT testing and fracture energy specifications for asphalt mix acceptance If needed, provide support to MnDOT for implementing the DCT testing specification.
