    Investigation of Performance Requirements of Stabilized Full-Depth Reclamation
    (2016-05) Milavitz, Rose
    Stabilized full-depth reclamation (SFDR) is a pavement rehabilitation method in which distressed asphalt is mixed with a stabilizer to form a base for new asphalt. SFDR has been used in Minnesota but there is a lack of guidelines for its design. This research investigates the relationship between SFDR properties and overall pavement performance, through which the desirable properties of SFDR materials can be determined. Material tests for creep compliance, Poisson’s ratio, tensile strength, dynamic modulus, and fracture energy were performed on SFDR samples from four roadways. The results were used to model the pavements using MEPDG and MnPAVE software. The rutting predictions were compared to the field measurements and parametric analysis was conducted to determine the effect of the dynamic modulus on the lifetime and reliability of the pavement. It was found that MEPDG can accurately predict rutting while MnPAVE is ideal for parametric and reliability analyses of SFDR pavements.
