Pavement Treatment Types

Asphalt Concrete Overlay

Asphalt Concrete (AC) consists of mineral aggregate bound together with asphalt, laid in layers, and compacted. The most common type used on streets and highways is Hot Mix Asphalt (commonly abbreviated as HMA).

Hot Mix Asphalt Overlay is regarded by most road departments as a standard for road maintenance and restoration, and has been for several decades. It produces durable, long-lasting results, and can increase pavement life by 15 years or more. Combined with other processes, such as milling or grinding of old pavement, an AC overlay can transform a tattered road surface into a like-new condition.

Cold-In-Place Recycling (CIR)

Cold-in-Place (CIR) recycling is a method of removing and reusing the existing asphalt surface. It involves grinding off the top 2 to 5 inches of the existing asphalt surface and mixing the crushed asphalt with an asphalt recycling agent, and placing it back down with a paver.

Full-Depth Reclamation

Full-Depth Reclamation is a type of complete road reconstruction where the old pavement and base materials are not removed. Instead, they are processed on-site. During this process, the old materials are pulverized, mixed, and treated with a stabilizing agent (such as cement or asphalt emulsion) to produce a like-new road base. Typically, the roadway is then re-surfaced with an overlay of new asphalt.

There’s no need to haul in aggregate or haul out old material for disposal. Truck traffic is reduced, and there is little or no waste. Due to reduced transportation, costs far less than the conventional approach to reconstruction. Can provide up to 30 years of additional life.
