Field Validation of Laboratory Tests to Assess Cracking Resistance of Asphalt Mixtures

Cracking is a primary mode of distress in asphalt pavements. There are several modes of asphalt pavement cracking—thermal, reflection, fatigue, and top-down—and all are affected by numerous factors and their interactions. Recent research has evaluated a variety of laboratory tests and models to assess the cracking potential of asphalt mixtures and several are recommended for routine use. As asphalt mix designs become more complex with the use of asphalt modifiers, reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS), and warm mix asphalt technologies, highway engineers have recognized the need to establish and implement reliable performance tests that can be used to evaluate asphalt mixes and ultimately extend the life of asphalt pavements. NCHRP Project 09-57, “Experimental Design for Field Validation of Laboratory Tests to Assess Cracking Resistance of Asphalt Mixtures,” developed experimental designs for the ruggedness testing and field validation of candidate laboratory tests to assess the resistance of asphalt mixtures to the four cracking types noted above. Candidate test methods were selected through (a) a critical review of relevant research and state mixture design practices and (b) a workshop with invited experts held in February 2015. The findings and conclusions of the project are summarized in NCHRP Research Results Digest 399: Field Validation of Laboratory Tests to Assess Cracking Resistance of Asphalt Mixtures: An Experimental Design; the contractor’s final project report is available at This project is the first in a series proposed to accomplish the field validation designed in Project 09-57. Research is needed to conduct ruggedness testing of the candidate test methods in anticipation of future field validation experiments. The objective of this research is to determine the ruggedness of laboratory tests identified in NCHRP Project 09-57 as candidates to assess the cracking resistance of asphalt mixtures. Ruggedness testing shall be conducted in accordance with ASTM E1169, Standard Practice for Conducting Ruggedness Tests. NCHRP anticipates that field validation of tests that demonstrate appropriate ruggedness in this project will be accomplished in future projects.
