Field Performance Evaluations of IL Aggregates for Subgrade Replacement & Subbase - Phase II

Important practical findings of the laboratory study and the developed aggregate thickness correction factors based on laboratory test results are to be validated in this Phase II field testing effort, which is the scope of the R27-81 ICT project work plan. Using the University of Illinois full-scale testing equipment ATLaS, field performances of the laboratory studied Illinois aggregates will be adequately evaluated for subgrade replacement and subbase in the Phase II research project ICT R27-81. The aggregate thickness tentative correction factors presented and the recommendations made based on the findings from the Phase I laboratory study will be validated and finalized in the Phase II field study to ultimately economize the use of aggregate in the State of Illinois by either reducing thickness or avoiding failures due to poor quality aggregate cover performances.
