Evaluate New Methods to Determine Type and Percentage of Stabilizer in a CSM Layer – Phase I

The proposed research will evaluate the feasibility of using petrographic analysis, x-ray fluorescence (XRF), and x-day diffraction (XRD) to determine both type and percent of stabilizer in a given sample of CSM. If this phase I effort proves feasible then a phase II will be recommended for applying these techniques to multiple sections included in the SS No. 263 research effort as well as for future use in estimating requisite CSM inputs to Pavement ME for design of rehabilitation projects. In addition, this proposed work assignment will assist Mississippi Department of Transportation (MDOT) with the effort to calibrate the Pavement ME performance models. This will include completing the AASHTOWare Pavement ME Design Input form for each of the 65 sample sections included in SS 263.
