An appropriate type of repair for many situations is the overlay patch. Hot asphalt is placed over the deteriorated area, and edges are feathered to overlap the surrounding pavement. The patch corners are squared, the asphalt is compacted, and edges are tacked down with hot tar. An overlay patch may be a good choice when deterioration is minor, and the base asphalt is not yet compromised. Overlay patches are much less expensive than excavation and replacement repairs. When pavement problems are severe, overlay patches are a temporary solution. In an overlay repair, old corrupted asphalt is not removed (except for loose pieces). New asphalt is placed right on top of the old pavement problem, and traffic will massage the new patch into the old topographical irregularities, causing the underlying problem to eventually “reflect” and reappear. Remember though, that your objective is to keep water out of the pavement base, and if you’re dealing with a limited budget, go ahead and do overlay repairs. They’re somewhat temporary, but effective. Metaphorically speaking, it’s a good idea to protect yourself from the elements by erecting a tent (if that’s all your budget allows). You can plan to build a house later. A caution about overlay patches… They sit above the level (grade) of your existing pavement, and the slight rise in elevation that patches cause, may affect drainage patterns, causing water to shift and pool on another part of the pavement. (Swift uses hot asphalt. Cold asphalt provides only the most temporary type of repair and will not last…always choose hot asphalt. Cold patch; however, does have an application in filling extremely wide cracks.)
