19.  Special thanks to the Asphalt Concrete Task Force, Tom Williams,
LaBelle-Marvin, Chair.
 The “Greenbook” has a long history of usage by local agencies in
Southern California.
 The “Greenbook” is consistent with the intent of standard
specifications, but does not contain, nor is intended to, all of the
specifics needed for comprehensive specifications.
 Participation on subcommittees and task forces is at an all time low.
For the “Greenbook” to continue as a sustainable entity, new and
broader participation from public agencies and consultants is
needed.
 THANK YOU FOR YOUR SUPPORT!
