Get PriceOnce 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.

Get PriceThe volume of intergranular void space between the aggregate particles of a compacted paving mixture that includes the air voids and the effective asphalt content, expressed as a percent of the total volume of the specimen. When VMA is too low, there is not enough room in the mixture to add sufficient asphalt binder to adequately coat the individual aggregate particles. Also, mixes with a low ...
