Asphalt paving is a very popular type of EARTHWORK. Paving roads, patios, driveways, and other such surfaces with asphalt pavements are very popular because asphalt itself is very durable. Asphalt also has a low-maintenance record, which makes it a popular choice for many commercial and industrial applications. But before you get your asphalt paving installed, you need to know the kind of asphalt you're getting.
Asphalt is basically a combination of aggregate, binders, and filler materials. The total mix used in asphalt paving consists of several components such as crushed gravel, sand, slags, or broken rock. But there have been several improvements in the production of asphalt over the years, mostly related to the ingredients used in asphalt paving. Nowadays, asphalt can be made using several types of asphalt materials, including thermoplastic, recycled rubber, recycled natural stone, and compressed natural stone (also known as silica). Some asphalt paving can also contain natural fibers such as wool or grass, which can make the asphalt surface warmer when it's used.
Before asphalt paving, the asphalt mix is prepared. In the past, asphalt was mixed by hand using crushed limestone (calcium carbonate) to pound the mixture into slabs. Newer asphalt paving mixes are created by electric spinning, which allows for faster mixing and more consistent results. The resulting asphalt mix is then compressed into a single, even sheet. This allows for a much faster drying time and keeps the asphalt moist throughout the paving process.
In addition to the materials and ingredients used to prepare the asphalt paving mix, the preparation of the asphalt pavements themselves is another important part of asphalt paving. After all, the asphalt surface needs to be flat and smooth before it can be properly laid. Car Lots driveways, especially, need to be flat and level to prevent drainage problems.
When the asphalt paving mix has been mixed and the surfaces have been formed, the asphalt contractors then apply what are called 'hydraulics'. These include concrete or water-based sealants. The purpose of these sealants is to help the asphalt surfaces stand up against moisture, as well as to keep them from shifting, which could cause cracks. Before the concrete or asphalt aggregates can be poured, they must also be cured. This process of curing involves allowing the concrete or aggregates to dry before the concrete or aggregates are added.
Lastly, the asphalt surface must be watered down to about thirty percent water drainage. This is done by applying what is called 'water control' to the asphalt mixture. By doing so, the asphalt will be less susceptible to any potential water drainage problems and stand up better against moisture. This type of asphalt paving does not lend itself well to very fast drying times, so it is important to use water control as the roofing contractor may recommend.
