Driveway resurfacing is the process of covering existing blacktop with 1 1/2-2" of new asphalt paving. Before driveway resurfacing we make sure to check for any areas that need to be repaired. If an area is broken or heavily cracked it needs to be removed and replaced with base material. In some cases fabric is placed on top of cracks to help stop the cracks from reflecting through the new asphalt pavement. In some situations the most cost effective option may be to cover and entire parking lot with fabric. This application is often used when an asphalt paving surface is still solid but has extensive alligator cracking.
When preparing a jobsite for driveway resurfacing, another step we take is milling. A milling machine is used to grind up blacktop. This is used to mill notches in the existing asphalt paving to ensure smooth transitions on a driveway resurfacing project. Milling can also be used to remove asphalt paving at areas that need to be lowered to allow proper drainage, for instance, garage floors, walks and curbs. Another application for milling is to scuff the surface of the existing asphalt. We prefer to do this when a surface has been sealed or when the surface is steep. Scuffing the surface helps the new layer of asphalt to bond to the existing surface which ensures the correct application of a driveway resurfacing.
We also take the time to remove all of the grass and sediment that is covering the edges of the existing blacktop. Once all of the milling and edging is complete, we sweep and then blow off the existing blacktop to obtain the cleanest surface possible. Tack coat is then applied to help the two surfaces bond together. Applying tack coat is an essential process of driveway resurfacing that cannot afford to be skipped. If the existing pavement has irregularities, a leveling course will be applied. A leveling course ensures that the final coat of asphalt will be uniform in profile, thickness, and compaction.

Asphalt Paving Prep
The most important aspect of all asphalt paving is a solid foundation. When starting a new project, it is vital to have the soil graded properly. If the soil is not stable we will remove the unstable soil until we find a solid foundation. When necessary we will use a soil stabilization fabric which prevents soil from coming in contact with the stone. Once a solid foundation is established, stone is then placed. We recommend a minimum of 6" of stone on all paving applications. We place the stone with a grader, ensuring proper slope to allow for drainage. The stone is then compacted with a vibratory roller. We use a jumping-jack tamper to compact the stone wherever the roller cannot get to. It is especially important to use a tamper in front of garage doors to help obtain maximum compaction.
