As asphalt ages and begins to deteriorate because of either bad drainage, root damage, or sub-grade failure, it will begin to crack. Cracks create avenues for water to infiltrate in to the sub-surface. Wet, frozen, or spongy sub-grade will cause asphalt to flex and crack even more. When cracks begin to appear it is very helpful to clean and fill them with hot tar crack filler to slow down the water infiltration process and extend the life of the surrounding asphalt.
One way to repair areas of multiple cracking (alligatoring) is to cut the perimeter of the damaged area and remove and replace the asphalt. Once the asphalt is repaired it is important to seal the joints between the old and new asphalt with hot tar crack filler to minimize the chance of water infiltration in the future.
If replacing a rather large parking lot or driveway is what you want, then an asphalt overlay may be an option. Both asphalt and concrete surfaces can be overlayed if the existing conditions are not too bad. If there are obvious areas of sub-grade damage, then these areas should be removed and replaced prior to any overlay. After cleaning the existing surface thoroughly and drying any wet spots the surface is coated with tack (CSS-1), which acts like a type of glue to help the new asphalt stick to the old surface. Once the tack coat has been placed a weed killer should be applied in areas of any cracks to kill any weed presence that may exist. If the surface to be overlayed is uneven it should be pre-leveled with a very thin layer of asphalt hot mix to fill in any voids and to provide a uniform surface to overlay. The typical thickness of an asphalt overlay is 1.5"- 2" of asphalt hot mix.
In circumstances of a new parking lot or driveway a good solid base must be prepared prior to asphalt placement. Typically, a 2" - 6" base of crushed rock is placed and fine graded in preparation for paving depending on the condition of the sub-grade. Remember, asphalt is only as good as the ground underneath it, so a good proper base is essential. Once the crushed rock base has been prepared and compacted thoroughly, the entire surface should be covered with weed killer prior to paving. The depth of asphalt laid will depend on the intended use of the new paved areas. Standard driveways and parking stalls usually only require 2" of compacted asphalt. Drive lanes or heavy traffic areas should have 3" - 4" of asphalt. Class B or 1/2" HMA asphalt should not be laid in a single lift greater than 3" depth. If 4" of asphalt is desired it should be laid in two separate 2" lifts to ensure proper compaction.
Crushed Rock Placement/Grading
If a smooth crushed rock surface is what you desire, we are happy to provide this service as well. We can place and fine grade crushed rock in new areas or simply fine grade existing areas and add crushed rock as needed. During and after the grading operation the crushed rock will be compacted thoroughly to ensure a solid smooth surface.
