Abstract:The objective of this project is to evaluate published literature regarding the efficacy of IDEAL-CT and IDEAL-RT test methods to characterize the performance of asphalt mixtures in the field. Many agencies have used and researched these 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 LWT and SCB. In order to perform a comprehensive study, LTRC will review published records of IDEAL-CT and IDEAL-RT and develop a summary to provide 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 DOTD in determining the viability of these test protocols to be used in BMD specifications.
