Understanding the Stages of Asphalt Maintenance over a 20 year lifespan
Stage 3 - Complete Reconstruction
The final stage of repair in pavement's life cycle is the complete removal and replacement or reconstruction of the pavement surface and stone base. The old, deteriorated asphalt is removed and transferred to a legal dump-site. If any stone or sub-base has co-mingled with the existing dirt based it must be replaced prior to the installation of new asphalt. Asphalt is then reinstalled in two "lifts". The first lift is normally 2 1/2 inches of Binder asphalt, while the second lift consists of 1 1/2 inches of wearing-course surface asphalt.
Given the excessive cost of complete pavement reconstruction, it is much more cost effective to remain in the preserve and maintain stage.
Stage 2 - Repair and Rehabilitation
If our asphalt pavement is past the preserve and maintain stage, a pavement evaluation should be done to determine what type of repair should be performed on the deteriorated asphalt to achieve the preserve and maintain stage again such as an overlay or sectional areas of removal and replacement.
As a rule of thumb, if 25 percent or more of the pavement surface is deteriorated, resurfacing should be considered with removal and replacement of high severity alligator cracking. If low to medium severity alligator cracking is present, the use of a petromat fiber should be an option to reduce the reflective cracking from extending through the newly resurfaced pavement.
A typical resurface would install 1 ½ inches to 2 inches of new asphalt over the existing asphalt surface. The pavement would have the same appearance it had when it was new at a fraction of the original cost.
Stage 1 - Preserve and Maintain
Our goal is to keep our pavement in the preserve and maintain stage as long as we can through the use of cracksealing, sealcoating and freshening up of lot marking. Cracksealing is the best preventative pavement maintenance investment a business owner or property manager can make. Cracksealing protects the sub-base and stone base from moisture infiltration, repeated freeze-thaw cycles and the damaging effects of vegetation, dirt and debris can cause within the crack.
Sealcoating provides a protective barrier to stop water from penetrating the pavement surface. By applying a commercial grade sealcoat over asphalt pavement, not only do we restore that "like new" look of a jet-black pavement surface, we also do much more by protecting the surface from oxidation, raveling, moisture accumulation and the harsh effects of oil, gas, and other damaging fluids.
