What’s New at ISCP

 

Greetings From the President

 

Best wishes for the new year to all! Year 2005 was a great year for the Society and we plan to continue our efforts to do even more for the membership during 2006. This year will also bring in new leadership to manage the many activities of the Society. As you will recall, the balloting for the officers and the Board was carried out a few months ago. A slate, developed by the Nominating Committee, was recommended and approved by the membership. The following are the officers and board members for the new term, beginning February 1:

 

President: Dan Zollinger (USA)                          

Vice-President: Kathleen Hall (USA)         

Secretary-Treasurer: Mark Snyder (USA)

 

Directors:

1.       Jamshid Armaghani (USA) - 2 years

2.       Jose Balbo (BRAZIL) - 4 years

3.       Michael Darter (USA) - 4 years

4.       Anna-Carin Brink (S.AFRICA) - 4 years

5.       Neeraj Buch (USA) - 2 years

6.       Jean-Pierre Christory (FRANCE) - 4 years

7.       Juan-Pablo Covarrubias (CHILE) - 4 years

8.       James Grove (USA) - 4 years

9.       Fred Hejl (USA) - 2 years

10.     Andre Jasienski (BELGIUM) - 4 years

11.     Gerry Krozel (USA) - 2 years

12.     Tatsuo Nishizawa (JAPAN) - 2 years

13.     George Vorobieff (AUSTRALIA) - 2 years

14.     Leif Wathne (USA) - 2 years

 

In addition to the above leadership, we also have many members who serve as liaison to the Board – representing their organizations or their countries. The incoming officers and directors will be installed at the January 2006 Board and Membership meeting.  All officers will serve 4-year terms.  As shown, seven directors will serve 4-year terms and another seven will serve 2-year terms, in accordance with the board action taken at the August 14, 2005 meeting. I would like to thank the outgoing Directors for their valuable time, support and advise over the last four years.

 

The state of the Society is very good, both financially and in terms of membership. We have a good core membership and are striving hard to increase the core membership and organizational members. During the conference years, our membership swells and the core members continue to renew membership every year thereafter.

 

The society will also be in good hands, under the new leadership of Dan/Katie/Mark and the new Board. Work will continue on initiatives already in progress and we can count on new activities that will make the Society more progressive and more dynamic. We will be discussing many of these items at the next Board and Open meeting and we will be seeking your advise on the these items.

 

As you have been alerted by Mark and as noted elsewhere in the newsletter, our next Board and Open meeting will be held on Sunday, January 22, 2006 at the Marriott Hotel (Carolina Room) at 5:30 PM, in conjunction with the 85th Annual Meeting of the Transportation Research Board in Washington, DC.

 

In closing, I would like to thank you all for your continued support of the Society. It has been my good fortune and a pleasure to have served as your President over the last four years. I hope to see most of you on January 22.

 

Shiraz Tayabji, President, ISCP

Honorary Member Feature

 

As a new feature to the quarterly e-newsletter, ISCP will feature an honorary member to pay tribute to their respective contributions to the field of concrete pavements.  The first honorary member to be featured is Gordon Ray, who unfortunately passed away earlier this month.

 

“Dean of Concrete Paving” Gordon Ray Passes Away at Age 86

 

Gordon Keith Ray, 86, of Arlington Heights, Illinois, one of the country’s best-known paving engineers and an internationally recognized authority on the design and construction of concrete pavements for roads and airport runways, passed away on January 4, 2006.  

 

A registered professional engineer, Mr. Ray was employed by the Portland Cement Association (PCA) for 38 years, directing the Skokie, Ill.-based trade group’s paving and transportation department and later the public works division.  For many years he also taught courses in pavement design and construction at Purdue University and the University of Wisconsin.  His many lectures about the use of concrete and soil-cement earned him the title of “Dean of Concrete Paving.”

 

As a young civil engineer at PCA, Mr. Ray teamed up with Kansas State University professor Gerald Pickett in 1949 to create the Pickett & Ray Influence Charts, a scientific guide to designing concrete pavements to withstand increasingly heavy modern trucks and aircraft.  He confirmed the charts with field-based research and pavement surveys in Illinois and Ohio in 1946 and 1947 and as PCA’s observer at the McPherson Test Road in Kansas in 1949 and similar studies in Maryland, Idaho, and Illinois in 1950s. 

 

When this research conclusively demonstrated that concrete pavements outperformed competing asphalt, Mr. Ray and other PCA engineers toured highway departments to promote the use of concrete in the then newly authorized Interstate Highway System and other roads.  Mr. Ray traveled to all 50 states, 10 Canadian provinces, and 19 other countries and wrote numerous technical papers to promote concrete pavements to public works agencies, engineering schools, and others.  Eventually 65 percent of interstate highways were built of concrete. 

 

Ray’s Influence Charts and their successors guided the design of roads and civilian and military airports during much of the postwar construction boom.  U.S. and international highway authorities often sought his counsel on concrete pavement technology.

 

A Fellow of the American Society of Civil Engineers (ASCE), Mr. Ray served on ASCE committees on structural design, construction, maintenance, and operation of roads and runways and on the Permanent International Association of Road Congresses’ Technical Committee on Concrete Roads.  His contributions to his profession were honored with several awards, including the American Road Builders Association’s Paul F. Phelan Memorial Award and the American Concrete Pavement Association’s H.W. Hartman Outstanding Achievement Award.  The International Society for Concrete Pavements also conferred the status of honorary member to Mr. Ray during the 8th International Conference on Concrete Pavements in Colorado Springs, Colorado, USA this past August.

 

For more than 30 years, Mr. Ray participated in the National Research Council’s Highway Research Board.  There, he chaired its Steering Committee for the First International Conference on Concrete Pavement Design in 1977 and its successor in 1981.  Over time, as traffic and weather led to the need to upgrade and replace roads, Mr. Ray also helped shape the agenda for the Transportation Research Board’s National Seminar on PCC Pavement Recycling and Rehabilitation in 1981.

 

Mr. Ray’s enduring interest in concrete pavements extended beyond working hours, according to his daughter Katherine Nelson. “Dad loved to drive the interstates, and it wasn’t uncommon for him to pull off a highway on a family vacation to walk along a shoulder inspecting pavement,” Ms. Nelson said.  “He would look for symptoms like cracks or scaling in the pavement, and could diagnose whether a stretch of rough or crumbling road was caused by the wrong aggregate, improperly sawed joints, poor design, or some other problem.”

 

The International Society for Concrete Pavements offers its condolences to Mr. Ray’s family and regrets the loss of a great leader in our field.

The effect of early opening to traffic on fatigue life of concrete pavements 

 

Dr. Chul Suh

Concrete pavements are subjected to many traffic-load repetitions prior to achievement of their full design strength. The effect of early opening to traffic on the life of portland cement concrete pavement systems was evaluated using experiments and mathematical model. To quantify the loss of life due to early opening of a rigid pavement system, an appropriate fatigue equation is fundamentally required. A series of laboratory fatigue tests was performed on simply supported beams to develop appropriate fatigue relationships for typical, normal strength Texas paving concrete mixture designs. After completion of the laboratory testing, accelerated fatigue tests on full-scale concrete slabs were performed under constant cyclic loading. The concept of equivalent fatigue life was applied to correct the effect of the different stress ratios between field and laboratory testing. The laboratory beams and full-scale field slabs showed an almost identical fatigue relationship after the correction for the variance of stress ratio. On the basis of Miner's hypothesis of linear accumulated damage, an analytical model for the numerical simulation for the prediction of the loss of life of a portland cement concrete pavement due to early opening was developed. The numerical simulations were performed for the various assumptions and considerations for field conditions. The current opening criteria used by the Texas Department of Transportation appear to be reasonable based on the sensitivity analysis results.
