Quality Control/Quality Assurance Testing for Joint Density and Segregation of Asphalt Mixtures

The deliverables contained in the final report for this research will be the following: (1) evaluation of different longitudinal joint construction methods; (2) evaluation of permeability tests that could be used to identify poorly constructed longitudinal joints and the location of areas of segregated asphalt in the mat; (3) development of draft test methods for laboratory and field permeability testing; and (4) development of draft permeability quality assurance criteria for inclusion in a "percent within limit" specification.
