Q$2)$ The Marshall method was used to design an asphalt concrete mixture. A PG $64-22$ asphalt cement with a specific gravity of $1\mathrm{.}031$ was used. The mixture contains a $9\mathrm{.}5mm$ nominal maximum particle size aggregate with a bulk specific gravity $(G_{sb})$ of $2\mathrm{.}696.$ The theoretical maximum specific gravity of the mix$(G_{mm})$ at asphalt content of $5\mathrm{.}0\%$ is $2\mathrm{.}470.$ Trial mixes were made with average results as shown in the following table:
