When asphalt is installed properly the thickness of the material and its natural flexibility spreads out the weight of the load, which is ultimately supported by the base layer underneath.
Eventually these tiny cracks will spread upwards and outwards, growing quickly larger and causing the surface to deteriorate well before its lifecycle is over.

Asphalt that looks great and lasts longer. Once the topsoil and additional soil are removed, the subgrade must be compacted with a roller. Soft spots should be removed and replaced or stabilized. The final step with the subgrade is treating the area with a soil sterilizing agent. This will keep vegetation from growing through the pavement. Cars and light-duty trucks are the normal traffic for a driveway.
These vehicles do not normally cause pavement damage. At times, a heavy truck may use the driveway such as a construction delivery truck or concrete ready-mix truck. These heavy trucks will damage a driveway.
If these trucks must use the driveway, it is recommended to wait until a time of the year when the pavement and soil is either dry or frozen. The pavement structure and materials used will change as a function of subgrade strength and construction approach. Some projects will use full-depth asphalt i. The aggregate base will be covered with one or more layers of asphalt. The table below is the minimum pavement designs.
Each layer is the compacted thickness. At no time should less than 4 inches of an aggregate subbase layer be used. In addition, most homeowners will not have a soil strength test performed on their subgrade. Therefore, for silty and clayey soils, a medium or weak subgrade should be assumed. In time, pavement failures may occur due to settlement or weakening of the soil or aggregate base layers. These will result in localized failures or potholes.
To repair these failures, the area impacted should be cut out and the pavement material removed to the subgrade. The subgrade material may need to be removed and replaced or simply recompacted. Finally, the removed pavement material should be replaced with new asphalt concrete or a permanent asphalt patching material. As asphalt ages, shrinkage cracks will develop. Individual transverse and longitudinal cracks should be sealed with an asphalt-based material to reduce the amount of water infiltrating the underlying pavement layers.
If the cracking is extensive, then the pavement can be overlaid with a new AC surface or removed and replaced with a new AC surface. Overlaying can be performed on driveways without curb and gutter.
For driveways with curb and gutter, milling or asphalt removal may be needed to maintain surface drainage. In many ways, the surfacing of an existing aggregate or gravel driveway removes many of the issues associated with a new driveway. However, before the existing driveway is surfaced with asphalt concrete, the homeowner should do the following:. On average, one inch of asphalt pavement is equivalent to three inches of aggregate base.
As a result, choosing an aggregate base over a full-depth asphalt driveway will require a much thicker driveway overall. Each project is different and has external circumstances that may impact the driveway installation. The best course of action is to consult a professional for the best solution for any asphalt needs.
