2. Concrete pavement restoration - Wikipedia

   en.wikipedia.org/wiki/Concrete_Pavement_Restoration

   Dowel bar retrofit (DBR) is a process that re-establishes load transfer capability on joints and cracks by installing epoxy-coated, round steel dowels into existing concrete pavement across transverse joints and/or cracks. Slots are cut using diamond-tipped saw blades; the existing concrete is removed and the dowels are placed in the slots ...

   Non-shrink concrete backfill material that is tested as rapid set concrete patching materials is recommended for use on DBR projects. First, make two saw cuts in the pavement to outline the longitudinal sides of each dowel bar slot. Saw to a depth and length that allows the center of the dowel to be placed at mid-depth in the pavement slab.

4. Rebar - Wikipedia

   Rebar (short for reinforcement bar or reinforcing bar), known when massed as reinforcing steel or steel reinforcement, [1] is a tension device added to concrete to form reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension.

   When a concrete structure is designed, it is usual to specify the concrete cover for the rebar (the depth of the rebar within the object). The minimum concrete cover is normally regulated by design or building codes. If the reinforcement is too close to the surface, early failure due to corrosion may occur.

   Above the targeted bottom height (coplanar with the compacted sand and gravel topping) a separate grid of rebar or welded wire mesh is usually added to reinforce the concrete, and will be tied to the under slab "girder" rebar at intervals. The under slab cast girders are used especially if it the slab be used structurally, i.e., to support part ...
