Once the optimum asphalt binder content has been determined, the voids in mineral aggregate (VMA) needs to be checked. The owner/agency specifications will indicate the required minimum VMA for your project. VMA is the intergranular space occupied by asphalt and air in a compacted asphalt mixture. In a component diagram, it is the sum of the volume of air and the volume of effective asphalt.
