Photo 1 of Z pavers 19 1969

Joseph Peitz imports a paver manufacturing machine from Germany to New Jersey to produce 1 million sf (93,000 m2) of “Z” pavers for Roosevelt Island, NY. The machine leaves New Jersey when the project is built.

KNR Concrete is started by Wolf Mueller in Toronto, later purchased and renamed Unilock.

Photo 3 Massey Coal Terminal 1982

610,000 sf (56,700 m2) of interlocking concrete pavement opens at the Massey Coal Terminal in Newport News, VA. The pavers are subject to high loads from coal storage piles and abrasive loads from steel-tracked bulldozers.

1983

North Bay, ON, places 150,000 sf (13,900 m2) in downtown streets and sidewalks. This project confirms the ability of concrete pavers to survive harsh winter conditions on municipal streets.

The ASCE Journal of Transportation
publishes “Structural Design of Concrete Block Pavements” by Gonzalo Rada, David Smith, John Miller and Dr. Matthew Witczak. This paper demonstrates the application of AASHTO flexible pavement design to interlocking concrete pavements. This approach was initially developed by Dr. Witczak.

CPI hosts a focus group of prominent U.S. and Canadian pavement engineers (including Dr. Witczak) who propose steps for institutionalizing interlocking concrete pavement. Their report provides the framework for the next several decades: develop design guides; test methods, specifications and maintenance guides; do research and demonstration projects; and promote.

Photo 6a Shackel book cover Dr. Brian Shackel, a University of New South Wales, Australia, researcher on interlocking concrete pavements, publishes Design and Construction of Interlocking Concrete Block Pavements through Elsevier (230 pages). The book summarizes his and other’s research from the late 1970s through the 1980s. The book addresses many positive aspects of pavement performance. He later promotes interlocking concrete pavement in North America.
Photo 7 San Antonio San Antonio, TX, places 1 million sf (93,000 m2) of interlocking concrete pavement in streets and sidewalks in its downtown. The pavement is subject to constant bus traffic.

Dallas/Ft. Worth International Airport places 260,000 sf (24,100 m2) of concrete pavers in cross taxiways, saving the airlines over $4 million in delays.

The first sales school is held for industry product representatives. Over 25 schools are held in the coming years including ones on advanced technical topics.

1991

CPI issues CAD drawings of various concrete paver applications on 3.5 in. floppy disks.

1992

CPI supports bedding sand research by the Royal Military College of Canada. Results provide test methods and acceptance criteria for bedding sands in high traffic/load applications.

Photo 8 book cover CPI issues its first installation training manual, Building Interlocking Concrete Pavements. The manual becomes the blueprint for an installer certification program developed some years later.

NASA conducts skid resistance tests on interlocking concrete pavements using a B-737 aircraft tire in Langley, VA (25,000-lb wheel load). Skid resistance is similar to grooved concrete runway pavement. Dentated pavers provide additional structural lateral stability under high wheel loads and hard braking.


1993

The Segmental Concrete Systems Association is formed in Chicago, IL, later renamed the Interlocking Concrete Pavement Institute (ICPI). Sixty-six charter manufacturer, supplier and contractor members fund the upstart group.

Photo 9 first magazine cover 1994

The first issue of Interlocking Concrete Pavement Magazine is mailed to about 7,000 readers and featured 300,000 sf (27,900 m2) in Berth 30 at the Port of Oakland, CA.

1995

Interlocking Concrete Pavement Magazine first reports on permeable interlocking concrete pavements (PICP).

1996

ICPI introduces an installer certification program with a comprehensive student manual, course materials and instructor training. Some 15,000 contractors take the course in the coming years.

1997

The Pennsylvania Transportation Institute studies skid resistance of interlocking concrete pavements demonstrating characteristics similar to conventional pavements.

2000

ICPI releases the first edition of Permeable Interlocking Concrete Pavements – Design Specifications Construction Maintenance. Three more editions are released with the latest fourth edition in 2011.

The ICPI Foundation for Education & Research is created to advance the technical and educational industry subjects with an endowment goal of $5 million.
