Surface Treatment One-Sentence Description After the area is first prepared, 4 layers of stone are evenly spread using a dump truck with 3 layers of liquid asphalt sprayed between each of the stone layers -- each layer is compacted using a roller. Applications This product is good for use on roads, driveways, parking lots, and several other applications. A Surface Treatment can be applied over sub-bases of many types, such as: existing gravel, shale, and rock, old blacktop, old Surface Treatments, and over another product we provide - our Dust Oil Application. Description First, the sub-base must be prepared, if needed. This consists of ensuring the proper material is selected and applied based on the estimated traffic load - a more substantial sub-base is needed for heavier truck traffic than one that will be supporting automobiles only, for example. The sub-base must also be compacted sufficiently to ensure a long life expectancy of the application and graded to ensure proper water flow. Next, a layer of #2 washed limestone is uniformly spread over the area to be treated. This will provide structure for the materials to be applied on top of the #2 stone. After the #2 stone is applied, a layer of E-3 liquid asphalt is applied utilizing a distributor truck. Then, 1B washed limestone is uniformly spread over the liquid asphalt, and compacted using a roller. This process of applying liquid asphalt, 1B stone, and compaction is repeated until there are a total of three of these layers on top of the #2 stone. So, from bottom to top, the order of materials used in a Surface Treatment is: #2 limestone, E-3 liquid asphalt, 1B limestone, E-3 liquid asphalt, 1B limestone, E-3 liquid asphalt, and 1B limestone. Relative Cost Comparison A Surface Treatment, generally speaking, may be as low as 40-50% of the cost of blacktop. On the other hand, a Surface Treatment can be about 4 to 5 times more expensive than another product of ours, a Dust Oil Application - this is due to the fact that much more stone, liquid asphalt, manpower, and machinery time is used to apply a Surface Treatment. A Surface Treatment should be followed up one or two years after original application, with a Single Seal or a Double Seal. After the follow-up, a Surface Treatment should last from approximately 5 to 8 years before needing further maintenance, based on traffic, existing sub-base, and weather conditions.
