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.
