asphalt rubber

The first asphalt rubber project occurred July 2007 on Saskatchewan Highway 11.

The asphalt used in PFC mixtures contains a high amount of polymers (or asphalt rubber as an option).

Arizona has been the leader in using rubberized asphalt, but California, Florida, Texas, and South Carolina are also using asphalt rubber.

In addition to the polymers, PFC mixtures require the use of fibers (not required with asphalt rubber) and may require the use of lime.

Asphalt Rubber (A-R) SMA can be used as an alternate to the standard SMA.

Stone Matrix Asphalt Type C and Type F mixtures can constitute Asphalt Rubber binders.

Notes Porous Friction course (PFC) mixtures can either constitute PG-76 or Asphalt Rubber mixtures.

After about one year it was determined that asphalt rubber overlays resulted in up to 12 decibels of in road noise reduction, with a typical reduction of 7 to 9 decibels.

Rubberized asphalt concrete (RAC), also known as asphalt rubber or just rubberized asphalt, is pavement material that consists of regular asphalt concrete mixed with crumb rubber made from recycled tires.

Asphalt Rubber (A-R) PFC can be used as an alternate to the standard PFC. A-R PFC is generally more expensive than the standard PFC; however, its unique properties warrant its use in certain applications.
