Cracking is a primary distress mode of asphalt pavements that creates the need for their rehabilitation. All types of asphalt pavement cracking—thermal, reflection, fatigue, and topdown— are affected by numerous factors and their interactions.

The TRB National Cooperative Highway Research Program's NCHRP Research Report 987: Ruggedness of Laboratory Tests for Asphalt Mixture Cracking Resistance presents the results of ruggedness testing of eight laboratory tests for the cracking resistance of asphalt mixes and proposes revisions to the test methods based on these results.

Supplemental to the report are:

• Appendix A: Proposed Revision to ASTM D7313-20

• Appendix B: Proposed Revision to AASHTO TP 105-13

• Appendix C: Proposed Revision to AASHTO TP 124-18

• Appendix D: Proposed Revision to ASTM D8044-16

• Appendix E: Proposed Revision to ASTM D8225-19

• Appendix F: Proposed Revision to Tex-248-F Overlay Test

• Appendix G: Proposed Revision to AASHTO T 321-17

• Appendix H: Proposed Revision to UF-IDT Resilient Modulus (MR) Test Method

• Appendix I: Proposed Revision to UF-IDT Creep and Fracture Test Method

• Appendix J: One-Page Summary for Ten Cracking Tests
