PREGLUED CONCRETE KERBSTONES - TESTING AND PRACTICAL RESULTS

FOERLIMMADE BETONGKANTSTOED - FOERSOEK OCH ERFARENHETER

An account is presented of field tests on different methods of gluing kerbstones on to bituminous pavements and to each other. The equipment for testing the bond strength is also described. The kerbstones were preglued at the factory to ensure full coverage and equal glue thickness over the whole contact surface and to eliminate the need of gluing equipment at the construction site. Five different glues based on rubberized asphalt were tested. Various measures to improve the bond strength were investigated. As weather conditions varied considerably during the test period quite a number of parameters could be studied. A priming coat on the pavement was necessary to achieve satisfactory final bond strength if no heating of the preglued surfaces was applied. This method is not recommended, however, as the rate of growth of bonding strength so far is too slow under winter conditions. The best result was obtained when the glue layer was heated just before the curbstone was placed. In wet or cold weather a priming coat and heating of the two contact surfaces proved to be necessary. For rough pavements the glue layer has to be 2.5 mm thick, while 1.5 - 2 mm is enough for smooth pavements. /TRRL/
