Asphalt is a very durable, common material used in paving and road applications. The longevity of public roads and sidewalks is an indication of how reliable this material is. However, it's only long-lasting if it's used correctly. An Asphalt repair professional long Island locale can advise interested businesses on How to Improve Your Parking Lot with Long Island Asphalt.
A parking lot is a high-traffic area. If it's busy, there are always cars or other, heavier vehicles parked on its surface, or moving through it. The paving surface therefore needs to be secure and durable. Asphalt is usually used, because it has these properties. But it still needs to be laid using the correct technique.
The key concept involved in using it is that it should be supported by layers of other material underneath it. These secondary layers are obligatory, because the asphalt itself is not structurally strong enough to remain intact under the weight of the traffic. Without these supporting layers, or courses, the surface will fracture and deteriorate.
This substructure is, in turn, composed of different layers of aggregate, or crushed stone. There may be up to three such layers, or courses, depending on what the application of the paving is. The largest particles are placed in the lowest course, and they become progressively smaller as the courses ascend. The top layer is the paved surface itself.
To use the technical terms, the surface itself is known as the surface course. The one below it is the binder course. These two are not negotiable, and are always present in correct asphalt paving. The other two, namely the base and sub-base, are optional, depending on what the paving is going to be used for.
In order to determine how many courses there should be, and what they should consist of, the paver needs to have the necessary expertise. Those who are inexperienced or who are trying to do DIY paving should talk to a paving firm, since the surface won't perform as well as it should if it's laid incorrectly.
