» Asphalt Mixes

Gap-graded (stone matrix asphalt (SMA)) is a type of mix usually reserved for high-traffic and truck volumes on interstates and primary roads. These mixes generally cost more due to the strict aggregate requirements, higher asphalt cement contents, and the specialized asphalt plant equipment required.

Fix your mix

In addition, some specifications allow lowering the optimum asphalt content from mix design by 0.3 to 0.5 percent for field adjustments. Lowering asphalt content in the field often means our pavements are under-asphalted or dry. This can lead to early raveling and cracking since the binder serves as the glue.
