Literature Review of IDEAL-CT and IDEAL-RT Tests Methods for Balanced Mixed Design

The objective of this project is to evaluate published literature regarding the efficacy of indirect tension asphalt cracking test (IDEAL-CT) and IDEAL-RT test methods to characterize the performance of asphalt mixtures in the field. Many agencies have used and researched these balance mix design (BMD) methods, and reviewing their efficiency can provide the state of Louisiana with additional tools and help agencies compare the results with currently implemented test methods such as loaded wheel tester (LWT) and semi-circular bend (SCB). In order to have a comprehensive study, Louisiana Transportation Research Center (LTRC) will review published records of IDEAL-CT and IDEAL-RT and develop a summary for a better understanding of these methods. Additionally, limited laboratory tests will be performed to ascertain the ability of the IDEAL-CT and IDEAL-RT tests to provide similar field cracking and rutting performance rankings as the SCB and LWT tests, respectively. This study will aid Louisiana Department of Transportation (DOTD) in determining the viability of these test protocols to be used as tools in BMD specifications.
