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.
