1.1 This standard for mix design evaluation uses aggregate and mixture properties to produce a hot-mix asphalt (HMA) job-mix formula. The mix design is based on the volumetric properties of the HMA in terms of the air voids (V ), voids in the mineral aggregate (VMA), and voids . a . filled with asphalt (VFA).
particle size of the aggregate, which was adopted by the Asphalt Institute in 1964[~]. He based this relationship upon the bulk specific gravity of the aggregate and an air voids content of 5°/0 for the compacted mix. However, the background data for relating the minimum VMA requirements to the nominal maximum size of the aggregate was not ...

MasterTop 100 is a ready-to-use cementitious dry-shake surface hardener incorporating specially sized and graded mineral aggregates. When evenly distributed and finished over freshly leveled and floated concrete, it adds color and improves the wear resistance of concrete floors. Recommended for use:

Voids in the mineral aggregate (VMA) are the air-void spaces that exist between the aggregate particles in a compacted paving mixture, including spaces filled with asphalt. VMA represents the space that is available to accommodate the asphalt and the volume of air voids necessary in the mixture. The more VMA in the dry aggregate, the more space ...
