Late 1960s to the Late 1970s– Technology Transfer to the New World The European experience provided a platform to transfer interlocking concrete pavements to the New World. Some of the paths followed by growing industries in Germany and The Netherlands were also taken by the nascent industry in Canada and U.S. The first path was trailblazed by a German entrepreneur named Josef Peitz who introduced concrete pavers to the U.S. in 1969. He manufactured about one million square feet of Z-pavers for a development project on Roosevelt Island, a part of New York City resting in the East River next to Manhattan. The project was a long street designed mostly for pedestrian use and only trafficked by electric buses. Mr. Peitz manufactured the units on a German-made, Zenith traveling multi-layer machine in Jersey City, New Jersey, and trucked them onto Roosevelt Island. A ‘traveling’ machine meant the production equipment was set on wheels (or tracks on a concrete factory floor) enabling the machine to move forward a meter or so after molding a layer of concrete pavers, maybe 30 pavers in a layer, and placing it on a wooden pallet. The freshly molded pavers would immediately begin curing (hardening). The machine would place a layer on each pallet returning down the same path or track and extruding another layer of pavers on top of the previous. This process would proceed until nine or Concrete Z-pavers installed on Roosevelt Island in the late 1960s PHOTO COURTESY OF THEODORE LIEBMAN I C P I C O M M E M O R AT I V E P U B L I C AT I O N • 5
