Experts Join Panels to Guide
lndustry and Asphalt-Rubber Technology Transfer
Advisory Committees
Named
RPA President Jeff Smith announced
the appointment of two committees to serve in an advisory capacity
for the association's overall programs. The Advisory Committee
is comprised of the nation's leading research experts in the
use of Asphalt-Rubber paving materials. The Technical Advisory
Committee is made up of agency and private professional engineers
with expertise in asphalt paving operations.
Advisors
The Chairman of the Advisory
Committee is RPA Past President Tim Baker, formerly of Baker
Rubber, Inc. of South Bend, Indiana. Members include Professor
Carl Monismith of the Institute of Transportation Studies of
the University of California, Berkeley; Dr. Jon Epps, Professor,
Civil Engineering Department, University of Nevada, Reno; Dr.
Gary Hicks, Professor, Engineering Department, Oregon State University,
Corvallis, Oregon; and Douglas E. Bernard, P.E., retired Director
of the Office of Technology Applications, FHWA, Washington, DC.
The Advisory Committee will meet with the RPA Board of Directors
at the association's annual meeting to make recommendations on
the operations and overall programs of the association. Smith
said the association is looking forward to the guidance of the
committee, all of whom have a long association with the Asphalt-Rubber
industry.
Technical Advisors
FNF Construction Asphalt-Rubber Manager,
Mark Belshe, P.E., will chair the association's panel of technical
advisors who are engineers with years of experience in Asphalt-Rubber
research and field application. The committee includes George
Way, Arizona Department of Transportation, Pavement Services
Engineer; Joe Cano, former City of Phoenix Engineering Supervisor;
Gene Morris, retired ADOT Director of Research; and Jack Van
Kirk, Chief of the Flexible Pavement Section in the Pavement'
Consulting Services Branch of the California Department of Transportation
(Caltrans). The Technical Advisory Committee's role is to select
and monitor significant Asphalt-Rubber projects, advise the Association
on publication of technical data, establish construction and
quality control guidelines and to assist RPA in technology transfer
to state and local agencies and other organizations. Call the
RPA office (602) 755-1269 or Chairman Mark Belshe, FNF (602)
784-2910 to secure contact numbers for the Technical Advisors.
Asphalt-Rubber Fact
There are many processes for utilizing
scrap tire rubber in asphalt. The RPA supports only those processes
that have a long history of laboratory research and successful
field performance. Asphalt-Rubber also known as the wet process,
meets this criteria. As defined by ASTM D8-88, Asphalt-Rubber
is a blend of asphalt cement, reclaimed tire rubber, and certain
additives in which the rubber component is at least 15% by weight
of the total blend and has reacted in the hot asphalt cement
sufficiently to cause swelling of the rubber particles.
