Superpave Centers
Five Superpave Regional
Centers will provide the technical leadership and assistance to ensure that the
promise of more durable asphalt pavements becomes a reality. The centers will
evaluate Superpave equipment and methodologies and work with the highway
agencies and industry to put them into practice. The centers will also be an
important source of hands-on training for engineers and technicians at a local
level. Sharing knowledge of the Superpave procedures throughout the highway
industry will speed the implementation of Superpave as the standard for asphalt
binder selection and mix design. The Superpave Regional Centers are a unique
source of expertise and assistance for highway agencies in their quest to build
better, longer lasting roads.
The centers are
designed to be flexible and responsive to the needs of State highway agencies
and the asphalt industry. The regions for each center have not been rigidly
defined. State highway agencies, local agencies, industry associations, and
universities may establish relationships with any center they choose, working
with the center that best meets their needs. The centers are focused on
customer service and establishing a wide range of partnerships within the
highway community.
The Superpave centers
have general objectives to further develop the Superpave mix design and
analysis system. However, the intent is that each center also have the
flexibility to serve the needs of the partner groups participating in the
center. The following general objectives will be accomplished by each center
through specific projects identified by the partner groups.
1 . Provide local
training on Superpave equipment and procedures.
2 . Evaluate the
Superpave equipment and procedures.
3 . Conduct research
sponsored by pooled fund, individual public agency, or private industry.
4 . Support the
Long-Term Pavement Performance (LTPP) Specific Pavement Studies program, as
funded.
AASHTO Committee
Urges States to Partner with SUPERPAVE Regional Centers
At its April 1996
meeting, the American Association of State Highway and Transportation Officials
(AASHTO) Standing Committee on Highways passed a resolution urging its member
States to support the Superpave Regional Centers. The AASHTO Standing Committee
on Highways encourages a close partnership between State Highway agencies and
the Regional Superpave Centers. Specifically, the resolution recommended that
the State highway agencies provide funding support and loaned staff, and
participate in oversight of the center's operations.
As an ongoing partner
in implementing Superpave, the FHWA approves using the pooled fund mechanism
for States to provide resources to the regional centers.
Training
The Asphalt Institute,
under a contract with the FHWA, plays a central role in supporting the
activities of the five centers and the asphalt industry to develop and
implement the Superpave mix design and analysis system. Disseminating
information and providing on a national level are key responsibilities of the
Asphalt Institute.
The Superpave centers will bring training opportunities and hands-on experience
to a wider audience of engineers and technicians on a regional basis. Loaned
staff arrangements with State highway agencies and industry associations allow
the centers to utilize the expertise of seasoned professionals while training
them in Superpave equipment and methodologies.
The centers will
conduct training on the Superpave binders, mixtures, and mix design and
analysis systems. Specific training will be tailored to meet the needs of the
center's partner organizations. Regional center staff will be available to
provide off-site training or to assist in the design and evaluation of
particular pavement construction projects. To meet specific goals of their
partner groups, the centers may also be available for forensic analysis and
trouble shooting, referee testing, certification programs, proficiency testing
programs, and technology transfer.
Evaluating the
SUPERPAVE Equipment and Procedures
The research and
testing performed by the Superpave centers will validate the Superpave
equipment, methodologies, and prediction models before large investments in
actual pavement construction. This validation is being accomplished by a team
from industry, academia, and government on a regional basis, enduring that the
training and knowledge required by Superpave is disseminated nationwide to all
partners within the highway industry.
Each of the Superpave
regional centers is fully outfitted with the Superpave mix design and analysis
equipment. Two devices developed for use in Superpave mix analysis are the
Superpave Shear Test (SST), and the Indirect Tensile Tester (IDT). The FHWA
will make a pooled fund purchase of this equipment for all of the States. Under
the guidance of the Asphalt Technical Working Group, the FHWA procured an
initial set of SSTs and IDTs units. The TFHRC will participate in equipment
evaluation with the centers and conduct its own research on the Superpave mix
analysis. The knowledge gained by all the centers wil help to ensure that the
devices eventually purchased for the States will be proven, reliable, and
usable tools.
Research
The centers are
available as a resource for research and development activities in the area of
pavements and materials. Any center may establish a partnership for a specific
research project with public agencies, private industry, or universities. The
scope of the project and the source of funding would be determined by the
partners in the project.
LTPP Support
Depending on need and
availability of funds, the centers can be utilized to assist States in initial
Specific Pavement Studies (SPS) design, verification, and in-place pavement
analysis as part of the FHWA's Long-Term Pavement Performance (LTPP) effort.
Partnership for
Better Pavements
The road from
laboratory to full implementation can be a long one, especially when it
involves a technology as complex as the Superpave system. The Superpave
Regional Centers will make this road as smooth as possible by establishing
strong partnerships to serve the needs of public agencies and private industry.
The centers represent an unparalleled source of asphalt technology expertise,
capability, and support to assist in the implementation of the Superpave
system. The centers will rigorously evaluate Superpave equipment and procedures
while providing hands-on training and experience to pavement specialists
throughout the country. This partnership approach will make the promise of
better pavements a reality.
