SPR 21-600: Implementation Assistance for the Kentucky Crack Test (KYCT)

Kentucky is currently in the process of implementing an asphalt cracking test and Hamburg rut test for asphalt acceptance. As part of this process, various projects have been let or will be let soon and will include this type of testing conducted by the contractor and the Division of Materials on a pilot basis. The contractors will then share this test information with KYTC for further analysis to assist in the determination of appropriate threshold/acceptance levels of these tests. In addition, Kentucky has also made other changes in asphalt mixture design processes in recent years that should be included in this analysis. This research project would assist the Cabinet in collecting the necessary laboratory and field data related to these proposed tests, along with other project related data, from the individual construction projects,. The additional data would include, but not be limited to the following: pavement distress conditions, mix design and materials information, QC/QA data, construction information, in-situ pavement permeability and detailed joint density, etc. A centralized database will be designed and populated to house all the relevant data, which can be used for continued analysis
