Asphalt Mix Design

Marshall Method of Mix Design

Standard Asphalt Institute MS 2

The Marshall method of mix design is used to determine the optimum bitumen content of dense graded HMA mixes.

Percent Air Voids (Pa) - The volume of air voids in a compacted mixture, expressed as a percentage of the total mix volume.

Voids in the Mineral Aggregate (VMA) - The voids created by the aggregate structure of a compacted asphalt mixture, expressed as a percentage of the total mix volume. VMA represents the volume of air voids and effective (nonabsorbed) asphalt binder.

Voids Filled with Asphalt (VFA) - The percentage of the VMA filled with effective (nonabsorbed) asphalt binder.

Percent Binder Effective (Pbe) - The functional portion of the asphalt binder that coats the aggregate in the asphalt mixture but is not absorbed into the aggregate, expressed as a percentage of the total mix mass.

Percent Binder Absorbed (Pba) - The portion of the asphalt binder that is absorbed into the aggregate, expressed as a percentage of the total aggregate mass.

Bulk (Dry) Specific Gravity (Gsb) of Aggregates

The ratio of the oven-dry mass of a unit volume of aggregate (including both the impermeable and water-permeable void volumes) to the mass of the same volume of water.Determined as per ASTM C 127 and C 128 or AASHTO T 84 and T 85

Apparent Specific Gravity (Gsa) of Aggregates

The ratio of the oven-dry mass of a unit volume of aggregate (including only the impermeable void volumes) to the mass of the same volume of water. Determined as per ASTM C 127 and C 128 or AASHTO T 84 and T 85.

Effective Specific Gravity (Gse) of Aggregates

The ratio of the oven-dry mass of a unit volume of aggregate (including both the impermeable void volumes and the waterpermeable voids not filled with absorbed asphalt) to the mass of the same volume of water.


Binder Specific Gravity (Gb)

The ratio of the mass of a unit volume of binder to the mass of the same volume of water. Determined as per ASTM D70 or AASHTO T 228.


Theoretical Maximum Specific Gravity (Gmm)

The ratio of the oven-dry mass of a unit volume of asphalt mixture (including the volumes of the aggregate and binder only) to the mass of the same volumeof water. Determined as per ASTM D 2041 or AASHTO T 209.

Bulk Specific Gravity(Gmb)

The ratio of the oven-dry mass of a unit volume of asphalt mixture (including the volumes of aggregate, binder and air) to the mass of the same volume of water. Determined as per ASTM D 2726 or AASHTO T 166.
