The roads made with asphalt should have the strongest and most durable foundation that it can have. This lessens the risk of it cracking and being damaged due to weight and weathering, also helps it with the lifespan. The financial risk for this is really huge so you better invest in only the best quality and make sure you got the right contractor.
As what is mentioned, the base should be at its strongest which contributes to how good and quality the whole installation or structure could be. Asphalt paving Los Angeles would not work if the sub base is soft and already have initial cracks. That is why there is a need to get this initially done before the rest is applied.
For the first step, any unwanted materials should be dug out and removed from the job site. Dig to about a foot deep while removing loam, soft soil, and also stumps. It is not advisable to pave over an existing concrete or old pavement, since there is total uncertainty on the quality of the ground underneath.
The next is adding the base and the grading. These would be the materials beneath the final layers and should be the most important of all. Place here either crushed concrete or you can also use asphalt millings. The thickness should be about six inches.
The millings and crushed concrete are engineered for them to be used on these types of installation. Usually, a skidrow is used to spread these materials and make it evened out. Use a laser level or a transit in order to determine the water flow of the surface. With a vibratory roller, even it out every three or two inches until the desired thickness is there.
There are two layers of mixtures to be placed on the pavement. These mixtures should be from the plant nearest just to make sure that it is fresh and still hot when applied all over the surface. Depending on the contractor, usually there are two layers for parking lots and only one for driveways.
The layering is called a lift. The first lift consists of huge rocks to form the base course of the layer. This creates a harder layer in order to support more. The second layer or lift would consists of smaller and finer stones in order for it to create a smooth finish.
Lastly, you need to have this compacted for the surface to hold itself together. What is needed for this procedure is a vibratory drum roller to make the surface stronger and to smoothly finish it. The edges should have a slope of forty five degrees which is enough angles to support vehicle movement and weight.
The connection between this and other pavements should always be a diamond cut in order for both these surfaces to meet flush underground. The best way to make sure of this is through skim coating the layers thinly over the edges and nearby other surfaces. This allows snowplows to lift it up and it is too thin to support weight.
