ABSTRACT:
A rectangular dowel bar sleeve is disclosed for receiving dowel bars and tie-bars that allows opening and closing of joints between adjacent cast-in-place slabs and pavements while allowing differential lateral movement of adjacent cast-in-place slabs in either direction parallel to the longitudinal axis of the joint and while preventing differential vertical movement of the slabs on either side of the joint. A form panel having an alignment ridge and spaced apart holes for attaching blockout bars to the form panel is disclosed. The blockout bars can be used to accurately create voids extending perpendicularly from the form panel and having upper and lower surfaces that are parallel to the intended upper surface of the cast-in-place slab. A dowel bar sleeve positioner is disclosed having a flange portion for mounting the positioner to a form panel or facing and having a stub portion projecting perpendicularly from the form for accurately positioning within a cast-in-place slab a dowel bar sleeve so that the top and bottom surfaces of the dowel bar sleeve are parallel to the intended upper surface of the slab.
