OLD AND NEW CONCRETE ACTING TOGETHER AT BRIDGE REPAIRS

If the water-jet technique is used to remove the deteriorated top layer of a concrete bridge deck the deteriorated concrete can be replaced by a new concrete topping without providing the surface with stud bolts which traditionally have been used to ensure shear capacity. A good bond between existing and new concrete also demands careful compacting of the new concrete. Composite concrete slabs fulfilling these demands have developed ultimate loads comparable to those developed by slabs of similar thickness cast in one lift.(a)
