How to Install Cement Over an Asphalt Driveway

Although not the ideal driveway base, it is possible to install cement over an asphalt driveway. As asphalt is prone to freeze and thaw damage which may cause cracking from extreme temperature that could then cause damage to the cement layer, it isn't always the best idea to pave over an asphalt driveway. However, for those in less extreme climates (more moderate environments) and those who otherwise are unable to remove the previous driveway, it can be preferable to pave over the asphalt.

Cement pavers
Asphalt patching material
Edging (metal or plastic)
Landscape fabric
Coarse sand
Shovel
Wheelbarrow
Wooden board, such as a 2 x 4 (for leveling)
Tamper, either hand or mechanical
Wet saw
Fine or polymeric sand
Broom

Instructions

- 1
  Check that the asphalt isn't cracked or damaged before paving. If damage is found, repair it with a patching material. This includes any cracks, holes, chips or any other uneven or irregular surfaces. Make the surface as smooth as possible.
- 2
  Place a metal or heavy plastic edging at the edge of the driveway and sink it to slightly below the top of the new pavement.
- 3
  Layer the landscape fabric over the current asphalt driveway.
- 4
  Place a layer of coarse sand, at least 1/2 inch thick, over the fabric. Use a board to smooth the layer out and compact it with hand or mechanical tamper.
- 5
  Place the cement pavers. Be sure to place them as closely as possible, cutting to fit if necessary. Use a wet saw if needed to cut the pavers.
- 6
  Spread a fine or polymeric sand over the top once the pavers are firmly set. Sweep the sand into the joints and any nooks and cracks between the pavers. The smaller sand works its way into the tiny cracks better than a larger, coarser grade. Repeat until all the pavers are stable and solid.
