摘要：	In June 2005, a report with Modified Binder Selection Guidelines for Wisconsin was finished under the sponsorship of the Wisconsin Highway Research Program. The report name is Development of Guidelines for PG Binder Selection in Wisconsin (SPR# 0092-01-01). In that report five areas were covered for the guidelines: binder storage and stability; mixing and compaction temperatures of binders; fatigue characterization; low temperature cracking and rutting characterization. The results of the project included the development of new specification guidelines. The new specifications included some new parameters: Zero Shear Viscosity ZSV mixing and compaction temperatures limits; a critical cracking temperature obtained using BBR, DTT and Tg testing for low temperature characterization; a fatigue parameter called Np20 obtained by time sweep testing in the DSR; and a rutting parameter called Gv obtained by repeated creep and recovery using the DSR. The present report deals with the field validation of these new parameters.
