Asphalt pavement is commonly specified and referred to as the material of choice for the construction of commercial parking lots and roads due to it’s durability, cost effectiveness, aesthetics, and performance. When combined with proper and timely asphalt maintenance, pavement can last many years which is why its important to adopt and implement a proper pavement management plan.
Due to environmental conditions, chemicals, and general wear, all asphalt requires periodic maintenance to minimize the deterioration and damage endured over time. Early detection and repair of asphalt deterioration or failure is essential for extending the life of the pavement. Areas that are not maintained correctly or in a timely fashion will develop into costly future repairs. Proper and timely repairs such as crack sealing, patching, and asphalt resurfacing can minimize and help avoid such costly future repairs, make for a safer and more aesthetically appealing environment, and extend the life of your asphalt asset.
Removal and Replacement
Asphalt Patching is a common maintenance procedure and a cost-effective way of eliminating further damage, deterioration, and liability. In areas where pavement has deteriorated and/or cracked, water seeps beneath the pavement and begins to breakdown the subbase resulting in the formation of unstable asphalt and potholes. The affected areas are saw-cut, removed, paved with hot asphalt mix, and properly compacted. If detected in time, potholes are typically small, but the same method of asphalt repair can be used to address entire sections of pavement that have fallen into disrepair.
Asphalt Resurfacing, also known as an Asphalt Overlay, is a common option used, in most cases, towards the latter part of the pavement’s life cycle and/or in more severe cases of asphalt failure. When large sections of the pavement are experiencing alligator cracking (interconnecting cracks that form a block pattern which resembles “alligator skin”), grade depressions, or other defects, an asphalt overlay may be a cost-effective solution which repairs the flaws, adds life and structural integrity to the pavement, and provides an aesthetic improvement, giving the parking lot a brand-new appearance.
The Asphalt Resurfacing Process includes preparing and cleaning the surface prior to performing the work, in some cases removing and replacing severely deteriorated areas with new asphalt prior to the overlay (providing structural integrity for the new asphalt to be laid on), leveling low areas, adjusting for drainage structures, in some cases milling the surface at a specified depth, along with many other job specific needs. Following the necessary pre-paving preparations, the area is then paved with new asphalt at the specified depth then properly compacted.
