Characterization of Illinois Aggregates for Subgrade Replacement and Subbase
The overall objective in this project is to characterize strength, stiffness, and deformation behavior of various types and qualities of aggregate commonly used in Illinois for subgrade replacement and subbase. The project focus is on pavement construction working platform issues. The project will develop aggregate thickness correlations with aggregate properties to modify and improve the thickness requirement curve in Figure A-2 of the Subgrade Stability Manual based on laboratory and field performances. This way, aggregate characteristics will also be used when determining cover thicknesses.
