A remove and replace is exactly how it sounds, the existing asphalt is excavated or removed which reveals the gravel base. If there are any areas where the sub base is soft they will need to be undercut then fine graded to proper grade. An undercut is an area that needs to be fully excavated and backfilled with aggregate. Undercuts usually range in depth but for the most part are 8” inches in depth. After the existing asphalt is removed and the sub base is properly repaired a new layer of asphalt is applied and compacted to proper thickness. A remove and replace is more expensive and should only be considered if the existing drive is weakened by the structural integrity of the sub base, if there is a drainage issue that needs fixed, or if there are elevation issues. A remove and replace can be a great long term solution for your asphalt needs.
Every driveway is different and factors such as surrounding elevations, drainage and use of paved surface can help determine the correct course of action. Please contact us for an appointment with one of our asphalt professionals to determine the correct solution for your project.
