What’s
New at ISCP? President’s
Message
I would also like to
take this opportunity to thank the outgoing board members for the services
they have rendered over the past 4 years; we greatly appreciated their much
needed contributions and look forward to their continued participation in the
future. I particularly want to thank
Dr. Mark Snyder for all his work as the ISCP secretary and wish him well as
our new president. Recently, the Society
has made important strides in advancing ISCP as a key technical arm of the
paving community. Some of the most
important goals, in my opinion, have been the organization of critical
committees to improve the membership and the efficiency of the Society to
address the transfer of technology and information. To this end, I can’t express the rewards I
have had and the comradery I have felt working with many of you – some of the
most respected professionals in the pavement community - as we have worked
together over the past 10+ years to make ISCP a world-wide recognized and
sought-after technical asset. We have worked to build
the reputation of the Society to where it is today and I would like to be the
first to congratulate the new slate of elected officers and to wish them the
very best in the coming year. The
Society will be in good hands and I am excited about the future of ISCP with
what it holds in store for all those committed to active membership. In our last board
meeting, we recognized and discussed the need to expand the level of
participation of the Society members in the operational business of the
board. I encourage all to respond to
such requests and to support the new executive committee’s efforts to lead
the Society in the New Year. Dan Zollinger Outgoing ISCP President New

International Conference on Concrete Pavements. ·
Discussion of protocol for handling requests to co-host/sponsoring
future conferences, seminars and workshops, as well as criteria for deciding
to co-host these events. ·
Discussion of strategies for Society growth, including ways
to add value to ISCP membership. ·
Presentation of a template for the planned ISCP technology
transfer database. Complete details of the
meeting can be found in the meeting minutes, which are posted on the ISCP
website at www.concretepavements.org. Membership Renewals Due by Membership renewal
notices have been sent to all current individual and organizational members
of ISCP who haven’t previously paid their membership dues for 2010. Membership renewals are due and payable by Renewals can be
accomplished online through the membership renewal link on the ISCP website
or by mailing a cheque or money order to the Secretary-Treasurer’s office. Membership dues for 2010
are as follows: ·
Regular Individual Members: $75/year ·
Employees of Organizational Members: $40/year ·
Full-Time Student Members: Dues Waived (certification of
student status required) ·
Organizational Members: $1000/year As always, membership
dues can be prepaid for up to 3 years in advance (i.e., through 2011, 2012 or
2013) at the current rates to protect against possible future increases in
dues. Venue and Dates Announced for ISCP 10th

Thesis
Abstract EFFECTS OF THE
BUILT-IN CONSTRUCTION GRADIENT AND ENVIRONMENTAL CONDITIONS ON JOINTED PLAIN
CONCRETE PAVEMENTS Rania Elias Asbahan,
Ph.D. Advisor: Julie
Vandenbossche, Ph.D., Assistant Professor Slab curvature, which represents the
response of concrete pavement to environmental loads, influences the location
and magnitude of critical slab stresses and affects long-term pavement
performance. The purpose of this study
was to measure the changes in temperature and moisture profiles in a newly
constructed concrete pavement, to determine the deformed shape of the slabs
and the resulting stress and identify the relative contributions of built-in
and transient environmental effects over time. To do this, an instrumented jointed plain
concrete pavement (JPCP) was monitored over a two-year period. The built-in construction gradient is a
major factor contributing to slab curvature and stress. Therefore, first, static strain and
pressure gage data used to establish the built-in gradient and zero stress
temperature. Slab curvature was predicted using
measurements of temperature and moisture conditions in the slab and computed
using static strain and pavement surface profile measurements. It was found that the additional restraint
provided by the dowel and tie bars does not appear to significantly reduce
slab curvature resulting from daily temperature fluctuations or from
reversible drying shrinkage. It does
have a substantial effect on reducing slab curvature due to long-term drying
shrinkage. It was also found that the
slab curvature is predominantly curled upward (99 percent of the time),
resulting in top-down fatigue cracking, while it is traditionally assumed
that fatigue cracking in concrete pavements initiates at the bottom. Finite element models were developed to
study the effect of various environmental conditions and slab restraints on
the development of stress in the slabs.
The models were validated based on measured strain data. It was found that the effect of moisture
has the most significant effect on stress in the slabs. The measured curvature in the restrained
slab (tie and dowel bars) is over 50 percent lower when compared to the
unrestrained (no tie or dowel bars) slab.
This reduction in deformation resulted in a critical stress that was
20 to 22 percent larger for the restrained slab compared to the unrestrained
slab. Upcoming
