Prime Paving Contractors recently completed a parking lot expansion and rehabilitation project in Alpharetta, GA. The scope of work included milling out the existing pavement, and regrading and compacting the base material as necessary. The parking lot addition required sub grade preparation, base installation and asphalt paving. In the existing parking lot we identified unsuitable soils in the sub-grade which could have led to premature failure of the new asphalt. Prime Paving remedied this problem by undercutting and hauling of five truckloads of dirt and replacing it with multiple compacted lifts of GAB. Once the parking lot passed a proof-roll, we did what we do best, we paved it!
