CONCRETE PAVEMENT DESIGNS IN FIVE COUNTRIES OF WESTERN EUROPE

HIGHWAY BUILDING AGENCIES IN GREAT BRITAIN AND THE COUNTRIES OF WESTERN EUROPE USE A WIDE VARIETY OF CONCRETE PAVEMENT DESIGNS AS DO THE ENGINEERS FROM VARIOUS HIGHWAY DEPARTMENTS IN THE UNITED STATES. CONCRETE PAVEMENT THICKNESSES OBSERVED ON A RECENT VISIT TO FIVE DIFFERENT COUNTRIES RANGED FROM 5 TO 11 IN. ON A WIDE VARIETY OF SUBBASE TYPES AND THICKNESSES. JOINTING ARRANGEMENTS ALSO VARIED FROM PLAIN PAVEMENTS WITH A SHORT JOINT SPACING OF 15 FT TO PAVEMENTS CONTAINING DISTRIBUTED STEEL AND EXPANSION JOINTS AT APPROXIMATELY 120 FT. JOINTS WERE FORMED BY SAWING PREMOLDED FIBER INSERTS AND BY HAND-FORMING THE PLASTIC CONCRETE. IN ADDITION, SOME AGENCIES USE A PARTING STRIP THAT IS PLACED ON THE SUBGRADE BELOW THE DUMMY GROOVE. PRACTICES WITH REGARD TO DISTRIBUTED STEEL, LOAD TRANSFER DEVICES, AND TIE BARS ARE QUITE SIMILAR TO THOSE FOLLOWED IN THIS COUNTRY. ALL COUNTRIES VISITED HAVE EXPERIMENTED MUCH MORE EXTENSIVELY WITH PRESTRESSED PAVEMENT THAN THE UNITED STATES. BOTH HIGHWAY AND AIRFIELD PAVEMENTS HAVE BEEN BUILT UNDER A WIDE VARIETY OF SERVICE CONDITIONS. THESE INCLUDE POST-TENSIONED SLABS THAT ARE PRESTRESSED IN BOTH DIRECTIONS AND ALSO IN THE LONGITUDINAL DIRECTION ONLY. THERE ARE ALSO A NUMBER OF PRESTRESSED PAVEMENTS IN WHICH LONGITUDINAL PRESTRESSING IS ACCOMPLISHED BY THE USE OF FLAT JACKS AND END ABUTMENTS, EITHER FIXED OR ELASTIC, WITH OR WITHOUT TRANSVERSE STEEL. A REVIEW OF THE PRESTRESSED PROJECTS IN EUROPE INDICATES A NEED FOR ADDITIONAL RESEARCH ON THIS TYPE OF CONSTRUCTION IN THE UNITED STATES. /AUTHOR/
