Broken asphalt paving is a hazard on your property. If your parking lot has a wide, even crack or alligator crumbles, a customer might trip and fall. In addition, the big cracks and crumbles let rain sink under the asphalt. That causes the damage to your lot to get worse. Here's a look at how a contractor might go about broken asphalt paving repair.
Assess The Damage
Broken areas of asphalt aren't necessarily as easy to repair as simple cracks. That's because filling in the big cracks and crumbles might be only temporary. Broken areas could indicate problems with the base rather than the asphalt alone.
If the sand base under the asphalt is bad, it has to be repaired or the cracks and crumbles will return. A contractor will examine the damaged area to determine what's wrong. Then, they'll know how to make repairs.
Cut Out The Broken Asphalt
Before repairs can be made, the broken area of asphalt has to be cut out and removed. This could entail using heavy machinery to lift out chunks of asphalt and moving them to a truck to be hauled to an asphalt recycling center or dump.
When all the debris is cleared away, the asphalt contractor can see the base and undertake repairs. This may involve correcting the problem that led to poor drainage as well as compacting the base again.
Your parking lot needs to drain properly so standing water doesn't cause the asphalt to deteriorate. The lot needs to slope toward a drain grate or a buried drain. If necessary, the contractor can cut through good asphalt to bury a drain that carries water to a safe dumping place. They may also build up the base a little if it's sunken so that water no longer collects in a depression.
Add New Asphalt
Once new soil and aggregate have been added and compacted to the base, it's time to add all new hot asphalt to your parking lot to fill in the space where the old asphalt was removed. The asphalt is filled and compacted to seal it along the edges and to pack it into the hole.
Areas of broken asphalt paving repair will be darker and noticeable against the faded lot, but the new asphalt will fade in time too. The repairs should stop the deterioration of your lot and last for many years.
This type of repair should last longer than simply filling in alligator cracks or using cold asphalt to make repairs. Fixing the base and using hot asphalt follows the same method as building a new parking lot and should be a permanent repair.
