Question
An asphalt concrete mixture is to be designed according to the Marshall procedure. A PG 64-22 asphalt cement with a specific gravity (Gb) of 1.00 is to be used. A dense aggregate blend is to be used, with a maximum aggregate size of 3/4 in. and a bulk specific gravity (Gsb) of 2.786. The theoretical maximum specific gravity of the mix (Gmm), at asphalt content of 4.5%, is 2.490. Trial mixes were made with average results as shown in Table . Using a spreadsheetprogram, plot the appropriate six graphs necessary for the Marshall procedure and select the optimum asphalt content, using the Asphalt Institute design criteria for medium traffic(see Table . Assume a design air void content of 4% when using Table
