The types or sizes of cracks that asphalt driveways or parking lots develop highly depend on the traffic, weather or number of years they have to endure. If ignored or not repaired in a timely manner, the cracks will become deeper and form ugly potholes. Here are the common types of asphalt crack repair methods you may need for your cracked asphalt pavement:
1. Asphalt Patching
This is the simplest and most cost-effective procedure that is commonly used to repair minor cracks when they are just starting to appear. It is often recommended for cracks that are not more than four inches deep. It helps greatly in preventing the situation from worsening and avoiding costly repair expenses.
2. Removal and Replacement
As compared to patching, this technique is a bit complex and labor-intensive. It is highly required in cases that have reflective cracking, cracks that occur due to pressure from heavy cars or trucks that regularly pass over the same spot. They can also occur as a result of thermal or moisture changes under the soil.
3. Asphalt Resurfacing
In asphalt resurfacing, the top layer of the damaged asphalt is removed then carefully replaced with a fresh one, giving the pavement an entirely new look. It is a suitable solution for areas with alligator cracks (fatigue cracks) that are often caused by stripping or raveling.
4. Cold Milling
Also referred to as profiling, cold planning, rotomilling or asphalt milling, this process involves the use of heavy-duty cold milling machines to remove huge chunks of cracked surfaces in order to create a level foundation for stronger asphalt. It is a highly effective solution for repairing cracked asphalt pavements in commercial areas, such as malls, medical centers or factories.
