Abstract
DEFORMATIONS AT THE CORNERS OF PRESTRESSED AND REINFORCED CONCRETE SLABS WERE MEASURED TO STUDY WARPING AND ITS EFFECT ON THE STRENGTH OF PAVEMENT FOR KUWAIT INTERNATIONAL AIRPORT. THE PRINCIPAL VARIABLES FOR THE PRESTRESSED PAVEMENT WERE THE LENGTH OF SLAB, CONCRETE STRENGTH, AND COMPRESSIVE STRESSES THROUGH PRESTRESSING FORCES. FOR THE REINFORCED CONCRETE PAVEMENTS THE PRINCIPAL VARIABLES WERE THE LOCATION OF THE CORNERS AT WHICH THE MEASUREMENTS WERE TAKEN. THE OBSERVATIONS OF THE VERTICAL MOVEMENT DUE TO WARPING AT DIFFERENT TIMES AND DIFFERENT DAYS WERE RECORDED AND PLOTTED IN CURVES, FOR COMPARISON BETWEEN THE VERTICAL MOVEMENT AT THE CORNERS OF THE DIFFERENT SLABS. A LIMITED STUDY FOR THE EXTENSION OF THE WARPING ALONG THE TWO PERPENDICULAR EDGES MEETING AT THE CORNER WAS DONE IN ONE CASE. ALSO, A LOADING TEST AT THE CORNER OF ONE SLAB WAS DONE FOR INVESTIGATING THE VALUE OF THE LOAD REQUIRED TO BRING THE CORNER DOWN TO CONTACT POINT AND TO FIND OUT IF ANY FAILURE WOULD TAKE PLACE AT THE CORNER UNDER THE DESIGN LOAD. /AUTHOR/
