Moore evaluated seven surface mixes using five lab cracking tests. In his thesis titled “Evaluation of Laboratory Cracking Tests Related to Top-Down Cracking in Asphalt Pavements,” submitted to the graduate faculty of Auburn University Dec. That means mix design technicians and researchers seek the Holy Grail of cracking tests. To prevent a mix from succumbing to a cracking failure, mix design technicians want to detect the problem and nip it in the bud. A number of thesis papers now stored in perpetuity online discuss cracking problems occurring after placement of flexible pavement mixes and how to discern when a mix could be subject to cracking upon placement.
