UNUSUAL PRESTRESSED HIGHWAY PAVEMENT BUILT TO SERVE "TRANSPO 72" SHOW NEAR WASHINGTON

THIRTY-TWO HUNDRED FEET OF PRESTRESSED CONCRETE HIGHWAY PAVEMENT WAS PLACED DURING THE WEEK OF DECEMBER 1, 1971, ON THE ACCESS ROD TO THE DULLES AIRPORT SITE OF TRANSPO 72, THE TRANSPORTATION EXHIBITION TO BE HELD MAY 27 - JUNE 4, 1972. THE TECHNIQUES USED IN THIS DEMONSTRATION PROJECT ARE DESCRIBED. IT IS HOPED THAT, WITH THE ECONOMIES INTRODUCED BY FULL SCALE APPLICATION, THE ADVANTAGES OF MATERIAL COST SAVINGS (PARTICULARLY, THE AMOUNT OF STEEL) MAY BE FULLY REALIZED. THE STEPS INVOLVED IN THIS PAIRING TECHNIQUE ARE PRESENTED. THE TWO MAJOR AREAS OF CONCERN ARE GETTING WELL-CONCOLIDATED CONCRETE AT THE JOINTS AND IN DETERMINING THE TIME FOR TENSIONING.
