Asphalt
Drain Repair & Installation
Site drainage is an extremely important component in the makeup of your parking lot. If the parking lot is well sloped, water will naturally drain away and not cause premature pavement failure. Most parking lots however are relatively flat, for safety reasons, and therefore standing water can become an issue.
If water is allowed to remain on the pavement surface, it can easily percolate through the asphalt, (which is a porous pavement), and start to compromise the subgrade below.
In freezing climates, standing water that turns to ice poses an obvious liability issue.
Once any drainage patterns have been corrected, it is extremely important that catch basins are functioning properly to remove the water. Deteriorating catch basins also pose a significant liability hazard because of the depth a person can fall into if the basin collapses.
Subsurface water can be removed via installation of French drains. Call your Pavement Network professional for recommendations on drainage repairs and installations.
Repairs
As soon as an asphalt pavement is constructed, it starts the process of deterioration. If it is properly constructed, of course, it will need very little, if any, maintenance within the first couple of years.
However if there are some soft spots in the pavement or if maintenance is deferred for a period of years, potholes or alligator cracking (which indicates failure of the base layers as well as the surface layers of the asphalt) will need to be addressed.
In the old days, asphalt repairs consisted merely of cutting out the deteriorated area, re-compacting the sub base, and installing a full depth asphalt patch, or crushed stone and asphalt. While this is still a viable option for many projects, new technology has given the progressive paving contractor many more options. We can now tailor a repair program specifically for your parking lot, keeping downtime to a minimum and creating the greatest cost benefit ratio for you.
Your Pavement Network professional has at his disposal a full range of repair options, from basic remove and replace, to partial depth patching using milling machines, to infrared patching using extreme heat to give the asphalt new life. Of course it takes a trained eye to know when each of these techniques is best for the job. Call your Pavement Network professional for a free estimate.
Resurfacing
When a pavement system is close to the end of its life cycle, the existing surface should be overlayed with a new layer of asphalt to extend its wear life. However, care must be taken to address all cracked areas in order to prevent translation of cracks through the new surface.All broken areas that move under the weight of a loaded truck must be repaired with full depth asphalt. Isolated cracks must be sealed with a hot pour crack sealer to retard reflective cracking.
Communicate with tenants, distribute, post schedule. All cars must be cleared from each work section.
- Excavate and repair cracked areas using full depth asphalt. No surface mix is required, just binder asphalt.
- Completely clean surface of all vegetation and dirt with a broom tractor and forced air blowers. Install riser rings, if needed.
- Mill the transition areas and perimeter of lot to a depth and width sufficient to provide proper drainage of new surface. Mill around existing utility manholes, if needed.
- Apply some liquid asphalt emulsion to old asphalt to bond the new layer (at least 0.05 gallons per square yard).
- Install asphalt surfaces
