You might be wondering what happens after an asphalt paving inspection takes place. If so, you came to the right place. Here, we’ll break down step 200 in our 3-Step Guide to Asphalt Paving; a plan with options based on the inspection.
Step 200 to Your Asphalt Paving Project
Let’s say you just completed the first step in your asphalt paving project including inspection and coring. Now, you’re ready for the next step.
Based on a few factors, the amount of work that will have to be done will determine what the best plan of action is for your project. Some things we take into consideration include:
- The conditions of your parking lot or roadway
- The climate you live in
- The amount of maintenance you chose to do while owning your parking lot/roadway
All of these factors combined can factor into the overall scope of work and create a price difference based on the needs of your pavement.
Below, we’ll list out the various plans you may need to take to successfully complete your project.
Option 1: Basic Overlay
Option one would be to do a basic overlay to the existing pavement, which is the cheapest option. This choice should only be chosen if there are not a lot of existing failed areas or cracks that need to be taken care of before the overlay.
The scope of work for this option may include milling necessary keyways, applying a tack coat, and shimming any low areas. Please note that this option does not consider the curb reveals, etc. This option, depending if it is not done on deteriorated and failed pavement, will last about ten years and would cause the least impact on your commercial or municipal property.
Option 2: Repair Isolated Areas
The second option tackles any isolated deteriorated areas before paving, which involves cutting out and repairing specific damaged areas. These repairs involve saw cutting to remove any problems, and then, we tack coat these patches before paving in the excavated areas. The rest of the steps involve the same scope as option one.
Depending on the number of patches that are repaired, the repairs could increase the cost to option number one about twenty-five to thirty-five percent. This is based on repairing about ten percent of the pavement surface. With these repairs being done, your pavement will last about twenty percent longer than option number one. Option 2 would add an additional day to the schedule to make the repairs.
Option 3: Mill Off Existing Pavement
The third option involves milling existing pavement down one-half to two inches from the existing grade. Any milled material is then loaded into a dump truck and delivered back to a blacktop plant, where they reuse the material back into a new paving mix. Next, the surface will have to be shimmed and tack coated. Then, the final surface will be paved.
With this option, the existing curb reveals can be addressed better than with option number one and option number two. The cost for this option is about forty percent higher than option number one. Option 3 will give you a pavement life of about fifteen years.
Option 4: Remove Blacktop Down to Existing Sub-Base
Option 4 involves removing the blacktop down to the existing sub-base. This can be done with a milling machine or excavating the blacktop out with an excavator and bulldozer. Next, the existing sub-base gets proof rolled, and then, the sub-base gets a fine grade and compacted.
If you find that the existing sub-base is in good shape, selecting this option would be ideal. The cost would be two and one-half times that of option number one, about two times the cost of option two and three. With Option 4, your parking lot should last twenty years.
Option 5: Excavate Out All of the Sub-Base
The final option would be to excavate out all the sub-base and all the paving. The scope of this option is the same as option four. However, option 5 requires an additional step which is the removal and replacement of the sub-base. After the existing sub-base is removed, a twelve-inch course of type 2 crusher run sub-base would be placed and compacted over a soil stabilization fabric. You would then follow option four above. The cost of option 5 is about thirty to forty percent higher than option four.
