Acknowledgements This research was funded by the Mid-America Transportation Center. PRS Mediterranean, Inc. in Israel provided the geocell material and R.D. Johnson Excavating, Co., Lawrence, Kansas provided the RAP material and hot mix asphalt concrete. Undergraduate students, Byron Whitted, Brandon W. Basgall, and Guo Jun, provided great help in the experimental work. Mr. Jim Weaver, Laboratory Manager and Mr. Matthew Maksimowicz, Laboratory Technician provided their technical support throughout the experimental work. The above-mentioned financial support, material supplies, and individuals’ help in this research are greatly appreciated. xii
