Double Surface Treatment

Double Surface Treatment

Double or Multiple Surface Treatments are a cost effective alternative to Hot Mix Asphalt, generally constructed on a fresh, compacted granular surface.

They are constructed by spraying a uniformed application of asphalt emulsion with a Computerized Distributor Truck, followed by a layer of cover aggregate applied with a Computerized Chip Spreader. That is followed immediately by a minimum of two Pneumatic Rubber Tired Rollers (one Rubber Tire Roller may be substituted with a Steel Drum Roller on multiple surface treatment applications), which seats the aggregate properly into place.

Once the first lift is complete, the same process is repeated using an aggregate not less than ½ the size of the first application. It is completed with a Non-Vibrating, Steel Drum Roller following up behind.
