CHIP SEALS ARE REALLY BIG IN
TEXAS
The El Paso District of the Texas Department
of Transportation wins the honor of the largest chip seal project
in the world. The 310 mile project was constructed by International
Surfacing Systems (ISS) of Chandler, AZ, the largest Asphalt-Rubber
binder supplier, used 14,030 tons of binder. The project covered
11 different roadways in the district, and included Interstates,
state highways and farm to market roads. The average shot rate
of the binder was .65 but in a few areas the rate was increased
to 1.05 to handle special pavement needs.
Greg Erks, ISS Project Superintendent, attributes the success
of this enormous project to his talented crew and also the TXDOT
staff of District 24, David Head, Director of Construction; Tom
Mangrem, Area Engineer and Asgeir (Oscar) Asfeirsson, Project
Inspector. Erks said, "All maintained a demand for safety,
quality and professionalism throughout the project. The product
knowledge and experience of these TXDOT respresentatives ensured
the application and construction procedures were of the highest
standard. As the leader in the asphalt-rubber industry, ISS takes
great pride in being part of this record setting project."

Japanese Anti-Noise
Delegation Visits Arizona
In early November representatives of
the Sound Environment Protection Research Foundation and the
Japan Automobile Tire Manufacturers Association, Inc. (JATMA)
visited Arizona to review ADOTs use of AR surface courses to
mitigate freeway noise. The group was hosted by RPA during their
investigative tour of the Phoenix area. The delegates included
representatives from several road surfacing companies as well
as governmental departments. During their visit, the delegation
met with George Way of the Arizona Department of Transportation
and RPA Past President, Mark Belshe of FNF Construction.
According to President of the Sound Environment Protection Research
Foundation, Dr. Mitsuyasu Yamashita, a Road Surface Committee
is being established to specifically develop a noise reducing
pavement. The JATMA delegation will be a part of the committee.
According the RPA Deputy Director, Douglas Carlson, who organized
the tour, the delegation was impressed with the wide spread use
of Asphalt-Rubber in Arizona and expressed hope they can develop
a similar program in Japan to reduce roadway noise and utilize
the 12% of the country's scrap tires that are not currently being
recycled.
