What’s New at ISCP

 

Greetings From the President

 

Thank you very much to all who attended the 8th International Conference on Concrete Pavements, held during mid-August in Colorado Springs, Colorado. The conference was successful on all fronts. The technical program and the workshops were well received by the attendees, as was the social program. And the conference was a success financially. Colorado Springs did not disappoint us either. Overall, the weather cooperated except for disrupting the outdoor instrumentation demonstration program.

 

The conference would not have been a success without the excellent contributions by the authors and paper reviewers, the session moderators, the workshop organizers, and the hard work of the Conference Steering Committee led by Dan Zollinger. Also, Purdue University’s Conference Division, led by Nona Schaler, continued to excel in supporting the planning function for the conference.

 

The conference activities were attended by almost 500. The conference activities included a theoretical workshop on fracture mechanics, the main conference and the workshops, and a specialty workshop on airport pavement related alkali-silica reactivity issues. The conference statistics and other details, including award winners, are provided elsewhere in the newsletter. The ISCP Board also conferred Honorary Membership to Gordon Ray and Michael (Mike) Darter.

 

The next conference is targeted for August 2008. We expect to build upon the 8th Conference’s successes and plan for an even more comprehensive and exciting 9th conference. The venue is yet to be selected.

 

Finally, the balloting for the officers and the Board is in progress. A slate, developed by the Nominating Committee, was recommended. The new officers and the Board will take office February 1, 2006.

 

The Society, by means of the international conferences and other activities, is actively engaged in promoting technology and technical competence to improve concrete pavement performance and durability in a cost-effective manner. More work is still needed to continue to optimize the practices for concrete pavements. The future of concrete pavement technology is bright. Concrete Pavements, with an excellent service record in both highway and airport applications, will continue to be an important pavement alternative internationally. Thank you all for your support of the Society’s activities.

Colorado Recap

 

The International Society for Concrete Pavements was pleased to have held the 8th International Conference on Concrete Pavements from August 14-18, 2005.  Over 400 participants from all over the world converged on Colorado Springs, Colorado, USA for the event.  Noted experts in the field of concrete pavements gave over 75 technical presentations.  These formal presentations were also supplemented by hands-on technical demonstrations on the topics of the following:

 

1.      Mechanistic-empirical pavement design

2.      PCC mixtures and materials

3.      Noise issues related to PCC pavements

4.      Construction process control

5.      PCC pavement construction field demonstration

6.      Precast paving forum

 

In addition to the technical presentations and workshops, separate workshops on the application of fracture mechanics in concrete pavements (during the prior week in Copper Mountain, Colorado) and alkali-silica reaction (on Wednesday and Thursday of the conference week) were also well attended.

 

 

Another unique feature of this conference program was the addition of a student poster presentation area.  A dozen students from seven universities in the United States participated in this program by developing a poster on their current research.  Posters were left up for conference attendees to review and presenters were available for questioning by attendees and judges alike during two coffee break sessions.

 

ISCP would like to thank the volunteers, conference co-sponsors, authors, reviewers, session moderators, and exhibitors for making this conference successful.  Moreinformation on the 8th International Conference on Concrete Pavements, news on the 9th International Conference in 2008, and proceedings ordering information from this and previous conferences can be found at the Post-conference website at:

European Airport Pavement Workshop

 

The first European Airport Pavement Workshop took place in May at Schiphol-Oost, Amsterdam. Over one hundred participants from all around the world gathered to discuss airport pavements. 31 papers were presented in two days, divided roughly in two subjects: design & construction and measurements & maintenance.

 

According to the organizers, the international character of the workshop and the presentations from different countries were highly appreciated by participants. Each country has its own problems and solutions. And exactly this diversity and the possibility to share experiences made the workshop a success.

CHARACTERIZING EFFECTIVE BUILT-IN CURLING AND ITS EFFECT ON CONCRETE PAVEMENT CRACKING

 

Dr. Shreenath Rao

Currently working as a Senior Engineer

Applied Research Associates, Inc.

Champaign, Illinois, USA

Ph.D. in Civil Engineering at University of Illinois at Urbana-Champaign (2005)

Thesis Advisors: Professor Jeffery R. Roesler

 

Differential expansion and contraction between the top and bottom of a concrete slab results in curling.  Curling affects stresses and deflections and is an important component of any mechanistic-empirical design procedure.  A significant portion of the curling can be attributed to the combined effects of nonlinear “built-in” temperature gradients, irreversible shrinkage, moisture gradients, and creep, which can be represented by an effective built-in temperature difference (EBITD).

 

Several instrumented test sections with various design features were constructed and evaluated using the Heavy Vehicle Simulator (HVS) in Palmdale, California.  These instrumented slabs were loaded with a half-axle edge load without wander, to study the effects of curling and to fail the slab sections under accelerated pavement testing.  A procedure for estimating EBITD using loaded slab deflections was developed using the HVS results.  The advantages are that they can be used for measuring EBITD of slabs with high negative built-in curl and can also be adapted for a Falling Weight Deflectometer, making it an efficient and cost-effective procedure to backcalculate EBITD of in-service pavements.  Differences in restraints and variability in concrete material properties resulted in EBITDs ranging from -5 ºC to greater than -30 ºC.

 

The HVS field tests were also used to examine Miner’s hypothesis along with various fatigue damage models.  Results indicate test slabs cracked at cumulative damage levels significantly different from unity.  New models that incorporate both stress range and peak stresses were developed to account for transverse cracking, longitudinal cracking, and corner breaks.  For slabs susceptible to high shrinkage gradients, microcracking resulting from early-age restraint stresses that can vary considerably from one slab to another is proposed as a factor that significantly affected the nominal strength of individual slabs, resulting in variability in cracking performance.  A procedure to model slab strength reduction and slab size was developed using nonlinear fracture mechanics principles.  A parameter called “effective initial crack depth” was introduced to characterize the early-age surface microcracking.
