KC Asphalt, as with most asphalt contractors in the area, uses SS-1H asphalt primer (Tack Coat). The difference is in the application. This asphalt primer is designed to be spray-installed to cover 100 percent of the existing asphalt area to be overlayed.
Wedging is needed when there is a low or badly broken area that was previously removed. These areas will be filled with hot mix asphalt to establish a finish grade that allows for the new asphalt surface.
The new asphalt layer can consist of a minimum thickness of 1-1/2" all the way up to 4" of asphalt after compaction, depending on the weight of the vehicles driving on the new surface. Most applications require a 2" asphalt surface after compaction.
Some jobs require removal of existing asphalt surface around sidewalks, garage floors and street entrances to allow for proper drainage. If you do not allow for proper drainage you could unknowingly end up with severe water damage.
The existing asphalt to be overlayed needs to be cleaned properly. First, we remove loose or badly broken areas in the existing asphalt surface. Second, we remove the vegetation from the edges and out of any cracks in the existing asphalt surface. Last, we remove the fine particles of debris by using a high-speed power blower.
