JOINT DESIGN FOR CONCRETE PAVEMENTS

UNJOINTED PAVEMENTS ARE EXAMINED, INCLUDING THE INFLUENCE OF SHRINKAGE AND THE COMBINED EFFECT OF WARPING AND TRAFFIC LOADS ON TRANSVERSE AND LONGITUDINAL CRACKING. THE FOLLOWING METHODS OF CONTROLLING CRACKING ARE OUTLINED: PLAIN SLAB DESIGN WITH AGGREGATE INTERLOCK JOINTS, RANDOMLY SPACED, SKEWED JOINTS AND USE OF CEMENT-STABILIZED SUB-BASES. SHORTCOMINGS OF REINFORCED SLABS ARE LISTED, AND THE LOWER COST AND DURABILITY OF UNREINFORCED SLABS ARE EMPHASIZED. THE USES OF LONGITUDINAL AND TRANSVERSE JOINTS ARE DESCRIBED AND ATTENTION DRAWN TO THE FACT THAT CONTRACTION JOINTS ARE UTILIZED FAR MORE THAN EXPANSION JOINTS NOWADAYS. DETAILS ARE GIVEN OF A STUDY OF THE DIMENSIONS OF DOWEL-BARS IN CONTRACTION AND EXPANSION JOINTS. THE DIAMETER OF DOWEL BARS FOR 10,2 TO 30,5 CM THICK SLABS IS GIVEN IN TABULATED FORM TOGETHER WITH THE DEPTH AT WHICH THEY MUST BE PLACED, AND THEIR TOTAL LENGTH. /LCPC/RRL/
