Asphalt Problems and Solutions:

Do you see asphalt cracks that resemble the hide of an alligator? Unless cracks are repaired in some manner, the entire lot will have to be completely removed.

Solution:
Grind, or slot cut perimeter of alligatored areas. Compact sub-base to 90-95% compaction. Tack vertical edges and install Hot Asphalt Concrete in equal lifts and roll for proper compaction.

Do you see loose gravel piled up on the side or gutters? Loose gravel on top has oxidized and loosened the stone aggregate.

Solution:
Properly sealing the asphalt is the solution and the least costly of all maintenance programs, if applied correctly. Overlay with Hot Asphalt Concrete, 1 1/2″ to 2″ is best solution.

Do you see oxidation? The surface of the pavement is beginning to breakdown from the deteriorating  effects of sun and water.

Solution:
Seal with a high-quality refined coal tar emulsion or asphalt emulsion that is usually sufficient to prevent further deterioration.

Do you see pavement beginning to deteriorate? Total break down of the pavement is inevitable.

Solution:
If cracks are not too numerous and not too deep, a hot or cold crack filler should be used to repair the damage. Followed by seal coat.

Do you see pavement base that has collapsed? Erosion has caused the surface to shift.

Solution:
The decayed base must be replaced and compacted to insure a solid foundation upon which to patch. The hole must be slot cut with square sides, then tac-coat is applied to establish bonding between the new and old asphalt. Then filled with fresh asphalt and compacted to the level of the surrounding pavement.
