ACKNOWLEDGMENT The study reported herein was conducted by the Mississippi Department of Transportation (MDOT) under the sponsorship of the Federal Highway Administration, Mississippi Division Office. This work was accomplished during the period March 1995 through May 1999 under the supervision of Mr. Alfred B. Crawley, <strong>State</strong> Research Engineer followed by Ms. Joy F. Portera, <strong>State</strong> Research Engineer. This report was prepared by Messrs. Gayle E. Albritton, William F. Barstis and Alfred B. Crawley of the MDOT Research Division. The authors wish to express their appreciation to the many people whose efforts contributed to the success of this study. Acknowledgment is made to the late Mr. Glynn R. Gatlin who headed up the materials team for conducting Gyratory tests. Included on this team were Messrs. Muralidhar Seshadri and Gary S. Browning. Messrs. Johnny L. Hart and Reginald Jenkins supported the project by collecting the many modified asphalt samples. Appreciation is expressed to personnel of Ergon Techical Development who were most supportive in obtaining samples. Mr. John W. Avent of the Research Division was key to this successful project by providing support during paving of the many test sections. Additional acknowledgment is made to involved personnel in the Second District of MDOT. Much appreciation is given to Mr. Joe Welch, Manager for Lehman- Roberts Mississippi Operations, for his continuous support before and during the paving. During the period of this study, the Executive Director of MDOT was Dr. Robert L. Robinson followed by Mr. Kenneth I. Warren. The Deputy Executive Director / Chief Engineer was Mr. James D.
