2. Dowel bar retrofit - Wikipedia

   en.wikipedia.org/wiki/Dowel_bar_retrofit

   A dowel bar retrofit (DBR) is a method of reinforcing cracks in highway pavement by inserting steel dowel bars in slots cut across the cracks. It is a technique which several U.S. states' departments of transportation have successfully used in repairs to address faulting in older jointed plain concrete pavements.

3. 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 ...

4. Lift slab construction - Wikipedia

   en.wikipedia.org/wiki/Lift_slab_construction

   Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...

5. Pavement milling - Wikipedia

   en.wikipedia.org/wiki/Pavement_milling

   Following dowel placement, the slots are then typically backfilled with a non-shrink concrete mixture, and the pavement is diamond-ground to restore smoothness. This special milling process shortens the time to create slots from the traditional method which is labor-intensive.

   Concrete roadway in San Jose, California A concrete road in Ewing, New Jersey. Concrete surfaces (specifically, Portland cement concrete) are created using a concrete mix of Portland cement, coarse aggregate, sand, and water. In virtually all modern mixes there will also be various admixtures added to increase workability, reduce the required ...

   A precast concrete walled house under construction An example of low-quality precast concrete with exposed dowels, connectors, indications of cracks, and malformations, even during its installation, Barangay Lantic, Carmona, Cavite, Philippines Interior view of the walls, supports, and roof of a precast commercial shop in Williston, North Dakota, US.

8. Structural steel - Wikipedia

   en.wikipedia.org/wiki/Structural_steel

   The steel columns will be connected to the slab by bolting and/or welding them to steel studs extruding from the surface of the poured concrete slab. Pre-cast concrete beams may be delivered on site to be installed for the second floor, after which a concrete slab may be poured for the pavement area. This can be done for multiple stories. [17]

9. Concrete slab - Wikipedia

   en.wikipedia.org/wiki/Concrete_slab

   A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).
