One of the biggest sources of lawsuits are because they pose trip hazards and can cause vehicle damage, pothole. Potholes also allow water to penetrate your parking lot since they eventually deteriorate the base of your parking lot. Repairing the potholes quickly is important to prevent these problems. When it comes to potholes problems, it is far more cost-effective to patch and repair asphalt surfaces than to repave. The basics on how paving patches works and the basic asphalt patching techniques is what we at Andersen Asphalt & Striping would like to share today.
What are the Different Types of Asphalt Repair Techniques?
Surface Patching. For residential parking, this is a popular option and often recommended for areas that are cracking but not crumbling. During the patching process, asphalt glue is added to the patch area and hot asphalt is applied directly on top of the pre-existing asphalt. It is less expensive to do it this way compared to cutting out and replacing asphalt areas. Although a surface patch will help prevent water from further penetrating the asphalt, it is still a temporary fix, with an estimated lifetime of approximately two years, depending on traffic and use of the area.
Partial Patching. This method grinds off the top 2–3 inches of asphalt, replacing it with new compacted asphalt, and sealing the edges. Partial depth repair is only feasible when the deterioration occurs only in the surface layer of asphalt.
Asphalt Patching Removal & Replacement
A more permanent and more costly method is the removal and replacement patching to repair deteriorated asphalt. Once the decayed asphalt has been removed, the base should be leveled and compacted. Compacting each layer for a more stable, the new fresh asphalt patch is then applied in two layers, both about 1 and a half inches thick as a permanent patch. You should consider a total replacement or asphalt milling if more than 25% of your parking area requires.
Asphalt Patching – Cold VS Hot
Cold Patch. Since it can be applied right from the container without heating, was first recognized as a way to make road repairs quickly, cold patch also referred as cold mix or cold asphalt. Cold asphalt also doesn’t require any special heavy rolling machines or special applicators as it can be shoveled or poured into a pothole or utility cut and tamped down with a hand tool. A temporary fix for potholes is considered with a cold mix.
Hot Asphalt. This is a long-lasting durable product made from rock, sand, tar & Bitumen. It is extremely hot when it is first applied so that it can fit and be worked into the repair area. It becomes extremely solid as the hot asphalt cools it hardens. It takes approximately 24 hours for a hot asphalt patch to harden and be safe to drive on. Asphalt is considered as a more permanent solution, and it requires skilled workers and it can only be applied in hot summer.
