The recently released NCHRP Research Results Digest 399: Field Validation of Laboratory Tests to Assess Cracking Resistance of Asphalt Mixtures: An Experimental Design develops an experimental design for the field validation of laboratory tests used to assess the potential of thermal, reflective, bottom-up fatigue, and top-down cracking. The digest briefly describes the selected cracking tests, proposed refinements, the field validation plan for the selected tests, and associated time and cost estimates.
