Although asphalt parking lots can last anywhere from 20 to 30 years with proper maintenance, you'll eventually have to repave them in order to get a beautiful, smooth finish again. When getting the parking lot repaved, paving contractors will determine whether the asphalt base is still stable. If it is, you can reuse the asphalt base and only repave the surface. This can save you a lot of time and money; however, here are 3 types of maintenance services the asphalt base will need.
Grind Out Damaged Surface Imperfections
While the asphalt base may be stable, there may be surface areas that are slightly damaged, with signs of imperfections. For example, these areas might be rougher in texture or uneven. Before you can repave the parking lot, you'll need to fix these imperfections by grinding them out. If you don't, uneven surfaces or roughly textured surfaces in the asphalt base may compromise the structural integrity of the additional layer that will be paved over-top. Over time, these areas become more and more vulnerable and are more prone to becoming damaged.
Seal Minor Cracks and Holes
Although the asphalt base may be deemed stable, there may still be minor cracks and holes somewhere on the surface from expansions and contractions caused by temporal fluctuations. While these cracks and holes may not necessarily be a problem now, they can worsen with time. To prevent the cracks from widening or the holes from deepening, seal them up with a sealant. Flexible, hot, rubberized asphalt is usually used in these situations.
Clean Out Catch Basins and Manholes
When inspecting the asphalt base, most paving contractors will also recommend taking the time to clean out the catch basins and the manholes. The structural integrity and condition of asphalt can be easily destroyed by water. Because of this, you'll want to make sure that the asphalt base provides proper irrigation in the form of catch basins and manholes. You don't want the water to be getting diverted elsewhere.
If the asphalt base is still stable and reusable, there's no reason why you should waste it and tear it out to install a new one. By reusing the asphalt base, you'll be able to save a lot of time and money without compromising the quality of the parking lot repaving. All you have to do is make sure that you take the effort to remove imperfections from the base, and your parking lot will last for many years to come.
