The weight and specific gravity of various types of aggregates used in preparation of Marshall Mix design are specified in tabulated form. The weight and volume of one Marshall specimen is and 1000 gm and 500 cm3. Assuming the absorptions of bitumen in aggregates is zero. Determine the voids in mineral aggregate (in %, corrected up to two decimal places). Take unit weight of water as 1 gm/cc and neglect the weight of air in mix design.
