How is Asphalt Made?
We typically see asphalt on the roadways and in parking lots. Asphalt is a mixture of hydrocarbons that is heated until it achieves the consistency of tar. Reckoning on the amount applied for heating, the asphalt may actually take on a solid state or become the consistency of a very thick liquid. With other uses like in road building, semisolid asphalt is combined with other elements like crushed stone, gravel and sand to make up the compound used to provide cover on city streets and highways.
The hydrocarbon material used to create asphalt is derived from the left over after the gasoline, diesel and kerosene fuels manufacturer. Asphalt is actually a by-product of the residue left behind after the desirable crude oil and petroleum components have already been harvested. Bitumen is one of these by-products often referred sometimes to as asphalt oil. Aside from being derived from petroleum and an essential binding element in the cover for roadways, asphalt is used to patch or cover the worn roadway like a city street.
Asphalt that is heated to high temperature forms the basis for making of asphalt roofing as well as shingles that have been used to make roofs that are more secure and water repellent. By heating the asphalt to its proper temperature and incorporating cement to the mixture produces asphalt concrete.
There are recycling programs that are using asphalt together with rubber chips that are made from old tires to produce materials for walls and sidewalks, like the way concrete has been utilized for years. Its binding capabilities are the most important aspects of the substance and with the fact that once applied, it may take a long time to wear asphalt away.
The word asphalt has Greek origins with rough translation of the term to prevent from collapsing or falling down. Asphaltenes were used for years in roadways to prevent the roadway system from collapsing from everyday use and in protecting the roofs of different structures from falling down due to changing weather conditions. And finally, asphalt caulking has been employed for several times to repair any leaks in boats and ships.
