Evaluation, Comparison, and Correlation between the Idaho IT-144 and AASHTO T-84 Methods for Determining the Specific Gravity and Absorption Properties of Fine Aggregate

This project will determine the Specific Gravity and Absorption properties of typical aggregates used in Idaho pavements according to CoreLok and American Association of State Highway and Transportation Officials (AASHTO) testing procedures. The study will develop a correlation between the two test methods with a view to improving the accuracy and consistency of reported results. Aggregates used in Idaho will be tested and compared using both the CoreLok and AASHTO methods. The research data will produce best fit prediction models. Tests using both methods will be used in each districts’ lab in order to verify the results of the researchers study. The outcome will be used to prepare procedures for inclusion in the Idaho Transportation Department (ITD) Materials Manual.
