    Background: In the Superpave mix design method, specified volumetric mix properties are evaluated at a design air void content of 4 percent regardless of the traffic loading and climatic conditions. However, because of local experience and concerns about achieving adequate hot-mix asphalt (HMA) durability and performance, some agencies have modified this requirement.

    Dec 02, 2013 · The number of design gyrations (N des) is an extremely important parameter in the asphalt concrete mix design procedure using the Superpave method.The choice of N des is a function of total traffic during the pavement service life, expressed in ESALs. Asphalt concrete mixes for higher traffic levels are compacted to a higher N des as a denser mix resists rutting more effectively.
