This report discusses the basis of the original Marshall design criteria established by the Waterways Experiment Station and criteria used by the Asphalt Institute and Virginia Department of Highways and Transportation. Marshall test properties are discussed in detail, particularly the related physical concepts. Special attention is paid to obtaining the proper aggregate gradation through the use of the 0.45 power chart and the proper number of sieves for gradation control. Finally, 1979 field Marshall data from the eight construction districts are analyzed to provide an indication of the revision needed in the design criteria used by the Department. Use of these revised criteria is illustrated in a suggested design procedure.
