The Marshall Mix Design method was originally developed by Bruce Marshall of the Mississippi Highway Department in 1939 The main idea of the Marshall Mix Design method involves the selection of the asphalt binder content with a suitable density which satisfies minimum stability and range of flow valu

The optimum asphalt binder content is finally selected based on the combined results of Marshall stability and flow, density analysis and void analysis (Figure 3) Optimum asphalt binder content can be arrived at in the following procedure (Roberts et al, 1996 [2]): Plot the following graphs: Asphalt binder content vs density

Volumetrics in Asphalt Mixtures The question often arises about controlling asphalt mixtures during the mixture design process and during production Many people who are reviewing these numbers have a complete understanding of how the numbers effect the mixture, while some have little or no experience with these numbers This will try to explain

Density is usually shown as a percent of maximum theoretical (Gmm) or the specific gravity of the in-place compacted density divided by the Gmm Air voids is used interchangeably with density and is calculated: percent air voids = 100 – percent density Density is achieved by compaction of the paver-laid asphalt-aggregate mixture
