ASPHALT PAVING
Asphalt pavement maintenance starts with repairs due to failed asphalt pavement and the repair strategy, if deferred be as significant as resurfacing or complete replacement. Failures can occur as a result of water infiltrating through the cracks into the sub-surface (gravel and clay layers), and also from abuse or misuse where the designed thickness is not enough to support the weight of the trucks.
Removal and Replacement
Asphalt typically requires patching in the early life of the pavement leading to saw cutting, excavation (or milling) to remove the damaged pavement and replacement with new pavement. This type of repair is visibly noticeable when cracks develop in the pavement beyond the areas of the joints (not to be confused with crack sealing) in rapid proximity to each other forming a pattern of failure. This is called fatigue cracking or more commonly “Alligator cracking” based on the pattern the cracking forms.
Resurfacing
Many times, there is significant cracking in a pavement, but replacement of the entire parking lot is not required. In these cases, resurfacing (also known as an Overlay) is a long-term, cost effective solution to correcting the damage to your pavement. It is not uncommon to perform partial removal/replacement of the most heavily damaged areas while preserving the remainder of the pavement as-is. Attention to detail is critical to maintain drainage and milling (asphalt grinding) is often performed to ensure that all fixed elevations and match points between adjacent concrete/asphalt are preserved while allowing water to flow either off the pavement or into the storm sewer system.

Replacement / Rehabilitation
When replacement of an entire parking lot is necessary, it is important to consider why the parking lot failed. More often than not, when an asphalt pavement is completely replaced, there will be sub-surface base failure requiring the aggregate and possibly sections of the clay soils to be excavated. Typically, a lack of prior maintenance has allowed moisture and water to settle into the soils saturating the base causing additional weaknesses. This is an expensive maintenance strategy PLM tries to avoid at all costs through prior pro-active strategies.
