Milling is a process used to remove, scarify or plane an existing asphalt surface to a specific depth. Once the specified depth is achieved, the area is prepped and then paved back with new asphalt. Milling is an efficient approach to asphalt maintenance due to the high productivity and capabilities the process has to offer. Whether it’s milling patches or entire parking lots or roadways, those surfaces are removed and newly paved asphalt surfaces in a timely manner, reducing project completion time, without the extra time, costs, and inefficiencies that go into excavating the asphalt surfaces, which can be a very slow process. Milling machines are also great to maintain or alter existing grades on an asphalt surface. The milling process can be executed with numerous size machines from skid steer attachments for small areas to large milling machines that can remove entire parking lot and road surfaces.
Full Depth Reclamation, also known as Soil Stabilization, is a cost-effective process that can be used to recycle or replace failed asphalt pavement surfaces. Soil Stabilization is appropriate when the existing pavement is damaged and cannot be rehabilitated with simple resurfacing or the existing pavement distress indicates that the primary problem exists below the asphalt surface in the base and/or subgrade. This process rebuilds failed and worn-out asphalt roadways, parking lots, or any other asphalt surfaces. The old asphalt and base materials are pulverized, mixed with cement and water, and compacted to produce a strong, durable base for either a new asphalt or concrete surface. This process not only produces a very strong base for the new surface, but it also negates the need to haul in new aggregate or haul out old material for disposal. As a result, trucking/hauling traffic is reduced, there is little to no waste to dispose of, and significant cost savings for the new base materials no longer needed. Because the full depth reclamation process uses the materials from the deteriorated asphalt pavement and, with the addition of cement, creates a new stabilized base, this process is typically more cost-effective and efficient than completely replacing the entire roadway or parking lot from the base up. Full-depth reclamation costs are typically 25%-50% less than the costs of fully removing and replacing the old pavement. The reclaimed base will be stronger, more uniform, and more moisture-resistant than the original base, resulting in a long-lasting, low-maintenance pavement.
