Top Job did a careful analysis of the parking lot, including areas where sinking or pumping indicated impacted base material, as well as a detailed map of existing drainage. It was determined that by milling the existing asphalt into the base material, called “Full Depth Reclamation” the base could be fortified and reclaimed. Leaving most of the asphalt in place and turning it into base material had several distinct advantages:

1. Adding 3 inches of base to the existing base substantially increased load bearing capacity and QUANTITY of base material.

2. Mixing water resistant asphalt into the existing base, and breaking up any clay that had pumped, substantially improved the QUALITY of the base material.

3. The additional base material allowed the grading crew to rework the grade, resulting in superior drainage relative to even when it was first installed.

4. Very little asphalt had to be trucked out, or base trucked in, saving the customer hundreds of thousands of dollars.

Once the base was fully reclaimed, it was compaction tested and areas where reclamation was insufficient to restore the base were replaced, ensuring extended performance at minimal cost.

The main parking areas were paved at 3 inches, and the heavy truck lanes and storage areas were paved at 4 inches. Additionally, steel grid base reinforcement panels were utilized in areas where forklifts transitioned from cement to asphalt, ensuring proper disbursement of energy and a long service life.
