*This includes the thickness of both Binder and Top courses.

**Where Heavy Duty or Rut Avoidance mixes are used (see Appendix), lift thickness limits will yield a minimum combined thickness of 80 mm. SUPERPAVE materials require a minimum combined thickness of 80 mm (or 90 mm if ESALs exceed 3 million).

† Heavy traffic is defined as being made up of more than 10% trucks and assumes at least half of the trucks are at or near the legal maximum weight.

‡ Normal traffic is defined as being made up of less than 10% trucks and assumes at least half are at or below the legal maximum weight.
