A STUDY OF TRANSVERSE JOINTS OF VARIOUS SHAPES CONSIDERING THE TRANSVERSE FORCE TRANSMISSION AND THE SLIDING RESISTANCE OF THE DOWELS

UNTERSUCHUNG VON UNTERSCHIEDLICH AUSGEBILDETEN QUERFUGEN HINSICHTLICH DER QUERKRAFTUEBERTRAGUNG UND DES GLEIWIDERSTANDES DER DUEBEL

This study deals with three pieces of research into reinforced concrete slabs, carried out in recent years at the rural roads testing station of the Technical University of Munich under the auspices of the Federal German Traffic Ministry. The first part deals with the laboratory tests to determine the pull-out resistance of individual dowels in relation to their diameter, type and thickness of coating, temperature, pull-out speed and frequency of pulling-out. It was necessary to paint the dowels over the entire length with a thick bituminous or suitable plastic coating, in order to obtain a good performance from the joints. Fatigue tests under repeated vertical loading and repeated joint opening were carried out on larger, elastically bedded test specimens with standard joint construction and other dowel coatings, spacings and diameters. A governing factor in judging the effectiveness was the frequency of joint movement. Maintaining the usual dowel spacings and diameters in the traffic lanes and the use of a suitable dowel coating can ensure that even where the crack indentation fails, the efficiency index will not drop below 60%. /TRRL/
