More WMA Technologies Approved!

As of the January 9, 2013 update, Caltrans has pre-approved 9 warm mix technologies for the contractor option specification.  The contractor option specification for Warm Mix Asphalt allows the contractor to use warm mix as opposed to hot mix with no additional charge to Caltrans.  As a contractor you can use any of the technologies on the approved technologies with little to no additional work on your part.  You may also be able to use a technology not already pre-approved as long as you follow the approval process for new warm mix technologies found here.

The list of pre-approved technologies can be found here and has the following technologies as of 1/9/13.
