2006 Member Survey on ISCP’s Future Plans and Ninth International Conference
 Planning for the ninth international
conference on concrete pavements is underway! The steering committee
for the conference will be meeting in Chicago
in mid June to discuss the date, location, and program for the next
conference. The tentative date for the next conference is mid August
2008.
During this quarter we are conducting a survey of all individual and
organizational members of ISCP, to gather input on the Society's current
activities and future directions. This is your opportunity to let the
officers and directors of ISCP know what you think about the direction in
which the Society should head in the future. The survey also provides
you with an opportunity to comment on plans for the next international
conference.
The results from the survey will be reported to the Board of Directors at its
July meeting in Evanston, Illinois,
and will be summarized in the next quarterly newsletter. The survey
results will be used to develop a strategic plan for the Society. We
hope to have the first draft of this strategic plan ready to present to the
Board of Directors for discussion at its January 2007 meeting.
The survey is being sent to all members by
email, and responses should be sent to me at katiehall@concretepavements.org Even after you
return your response to the survey, please feel free to contact me at any
time at that email address with any comments or suggestions you have about the
work on the strategic plan or the planning for the ninth international
conference. I look forward to hearing from you.

In
1948, John Oremus founded Prairie Material with three trucks, a load of stone
and a  ton of ambition. John's success was built on the philosophy
of better service to the customer, and it is based on these three
principles: produce the highest
quality products at competitive prices, provide excellent customer service,
and always deliver products and services in a timely manner. These core values are still at the center
of how Prairie continues to uphold John's tradition of excellence.
Over
the years, Prairie has grown to be one of the largest family-owned and
operated producers of ready-mix concrete in the Midwest.
With four divisions serving customers in Illinois,
Indiana,
Michigan
and Wisconsin,
Prairie has the support structure in place to provide all the materials
needed, for any size project.
In
1981 Prairie acquired Illinois Brick, and in 1984 Prairie opened its first
stone quarry. Prairie now operates 12
quarries and has 17 brick locations.
ISCP's
member contact for Prairie Material is Mr. Gerry Krozel, Vice President, 7601 West 79th Street, Bridgeview, IL 60455

Major in Concrete Industry Management
A
new major in Concrete Industry Management (CIM) is being proposed by the College of Engineering,
Computer Science, and Construction Management at California State University,
Chico.
It is the result of a partnership between the concrete industry and the
university, which will offer students a unique blend of technical and
management preparation in a new discipline and will help to meet this industry's
employment demands. The proposed
program is similar to an existing program at Middle Tennessee State University
in Murfreesboro.
Two other programs are being developed, one in Arizona
to serve the Southwest and one in New Jersey
to serve the Northeast.
At
both the national and local level, the concrete industry is committed to
creating more training programs for interested students. "The CSU, Chico CIM program is heading
down the path of success due to the unique synergy of combining our excellent
faculty with a broad coalition of industry partners," said Kristin
Cooper-Carter, director of the program. "We are excited at the vast
opportunities that this program has to offer; our students will be the
ultimate benefactors of this partnership."
The
CIM curriculum for CSU, Chico has been
adapted to serve the climate, geography and needs of the West Coast and
Northwest regions. Courses that will be developed to meet California's
needs include: Sustainability and the Built Environment, Seismic Considerations
in Concrete, and Concrete Fixtures and Surfaces (cast countertops, texturing
and staining). "Other technical
fields also face an acute shortage of Technical Managers," said Dirk
Vanderloop, academic coordinator, CIM Program. "What sets the CIM Program
and the concrete industry apart is the cooperation, involvement and financial
support of companies, trade associations, professional associations and
individuals. They can be cut-throat competitors in the marketplace, but are
cooperating on this project. I've never seen anything like this collaboration
in all my years of working with industry.

ISCP Participates in International Scan on Long-Life Concrete
Pavements
 Dr.
Shiraz Tayabji, ISCP Past President, was invited by AASHTO to participate as
a member of the team selected to conduct an international scan of Long Life
Concrete Pavements. The 17-day scan
tour, undertaken during May 2006, visited Canada,
Germany,
Austria,
Belgium,
The Netherlands, and the United Kingdom. The scan tour was sponsored by the AASHTO/FHWA/NCHRP
International Scanning Program. The
scan team included fourteen concrete pavement experts and leaders from FHWA,
State DOTs, academia, and industry (including ISCP). Dr. Katie Hall, ISCP Vice President, served
as the Report Facilitator for the team.
The
goal of the scan tour was to identify successful design approaches and
construction practices for long-life concrete pavements. The following activities were conducted:
Canada
– meetings with the staff of the Ontario
and Quebec Ministries of Transport in Toronto
and visit to Highway 407 in Toronto
(Host: Tom Kazmierowski, ISCP member and former ISCP Director)
Germany
– meetings at the German Cement Works Association (VDZ), Dusseldorf;
the Federal Highway Research Institute (BASt), Bergisch Gladbach; and the Technical
University of Munich, Munich (Hosts:
Professors Bernard Lecher and Gunther Leykauf. Also participating were ISCP
Honorary Members Professor Rupert Springenschmid and Emeritus Professor Josef
Eisenmann). A site visit was also made to a CRCP test section south of Frankfurt.
Austria
– meetings at the Association of the Austrian Cement Industry, Vienna, jointly
organized with the Austrian Federal Ministry of Transport. Also, visits to
several concrete pavement projects. (Host: Dr. Johannes Steigenberger)
Belgium – meetings in Brussels organized
by FEBELCEM with the Ministry of Equipment and Transport of the Walloon
Region and the Infrastructure Agency of the Ministry of the Flemish
Community. Also site  visits
to several concrete pavement projects. (Host: ISCP Director André Jasienski,
FEBELCEM)
The Netherlands
– meetings with C.R.O.W. Technology Centre staff and site visits to several
concrete pavement projects. (Host: ISCP Member Adrian van Leest)
The United Kingdom
– meetings at BritPave (Host: David Jones) and TRL.
The
scan tour confirmed that well-designed and well-constructed concrete
pavements continue to be important pavement types in the countries
visited. All of the European countries
visited are responding aggressively to pavement-tire noise issues and the
exposed aggregate surface is the texture of choice in Germany,
Austria,
Belgium
and the Netherlands. In the UK,
the use of an asphalt-based wearing surface is mandated for concrete
pavements. Also, Germany
and Austria
have successfully implemented the use of catalog designs for their jointed
plain concrete pavements. Germany
requires use of a geo-fabric as a separator layer between the CTB and the
concrete pavement while the use of an AC interlayer is used in Austria. Belgium
primarily uses CRC pavements.
A
report detailing the findings of the scan tour and the recommendations for
implementing promising findings in the US
will be released later this year.

Seamless Pavement Will Be Closely Watched
The
M7 Motorway west of Sydney (Australia)
was opened to traffic late in 2005.
This new motorway uses the seamless paving technique described in the
award-winning paper at the 8th International ISCP conference and titled
“Design and Construction of Seamless Pavement on Westlink M7”. The 40km long motorway consists of thin
layers of open on dense graded asphalt, on 240mm thick CRCP supported by a
150 mm lean mix concrete subbase.
 The numerous small bridges on the
motorway lend themselves to the continuous paving operations on land and over
bridges without the use of terminal anchors.
Other benefits of the seamless paving are:
•
reduced maintenance at bridge abutments
•
improved ride at bridges
•
reduced noise due to no transverse joints at bridge abutments
•
elimination of bridge deck drainage
•
simplified construction due to no terminal anchors
More
details about the concrete pavement can be found in the paper.
Seamless
paving has not been trialed on this scale anywhere in the world and Australian
concrete pavement engineers will be eagerly watching its performance over the
next decade.

International Workshop in Brazil
ISCP is co-sponsoring (with the Brazilian Concrete
Institute, IBRACON) a workshop on the best practices for concrete pavements.
This workshop, to be held in Recife, Brazil,
will gather experts from around the world to present and share their
experiences concerning the best practices for concrete pavement design,
construction and management to produce long-life, low-maintenance concrete
pavements in any transportation setting.
Applications of interest include airports, streets and highways, heavy
duty floors and harbors, as well as urban infrastructure installations, such
as parks, sidewalks, parking lots, etc.
The workshop will address a broad range of topics,
including cast-in-place and precast paving, reinforcing issues and concrete
paving innovations, such as colored concrete and other architectural
considerations and applications.
The workshop is scheduled for October 21-23, 2007
(mark your calendar!), and abstracts are now being accepted for
consideration. Details concerning the
workshop organization and registration can be found at http://www.ibracon.org.br/pavement.workshop.
Finite Element
Simulation of curling on Concrete Pavements

Curling
results from the temperature and/or moisture differential across the concrete
pavement slab thickness. The slab
curls downward and upward when the slab experiences positive (temperature of
the pavement top is higher than the bottom surface) and negative temperature
differentials, respectively. Curling
affects the pavement smoothness adversely.
In
this study, three-dimensional Finite Element (FE) simulation of curling of
concrete pavement has been presented.
A finite element software, ANSYS was used to perform the
simulation. A number of FE models were
built using geometric and material properties obtained from several newly
built concrete pavements in Kansas. The pavement sections were modeled as a
three-layer system with Portland cement stabilized base (BDB) and
lime-treated subgrade. Materials in
different layers were modeled as linear elastic. Contact elements option available in the
ANSYS library was used to model the interaction between the concrete slab and
the dowel bars embedded in concrete.
Temperature data was obtained using thermocouples and digital
temperature data loggers. Regression
models were developed for curling deflection and International Roughness
Index (IRI), a roughness statistics, resulting from the curled profiles,
based on different simulation parameters.
Hourly curling deflections were also measured for several days on a
test section. The results obtained
from the field measurements were compared with the simulation results.
The
results obtained from the simulation show that the curling deflection and IRI
calculated form these deflected profiles are affected by the slab thickness,
compressive strengths of the concrete and base layers, and temperature
differential across the pavement slab thickness. Both curling deflection and IRI increase
with an increase in temperature differential between the pavement top and
bottom surfaces and compressive strength of the stabilized base layer. Curling deflections obtained from the field
measurement show trends similar to those obtained from the FE simulation and
are in very good agreements for lower tempe |
