An expanse of black asphalt for your Plant City parking lot paving is a familiar sight for many of us. Asphalt is a very durable material which is commonly used for construction work like road work. However, have you ever wondered about how it’s made and what about it makes it great for our roads and parking lots? Here is a brief overview on what asphalt is and how it’s made.
Interestingly enough, asphalt has been around for a significant part of world history. There has been evidence of the Sumerians using asphalt in their shipbuilding industry, and the ancient Egyptians used it as a waterproofing material and as a part of their mummification rituals. Asphalt was widely used in the building of temples and reservoirs.
The asphalt used by these ancient civilizations were naturally occuring minerals, commonly found in the layers of the earth. These were used in its natural form and occurred either as soft, almost moldable material, or as a hard, brittle mineral. Natural asphalt is made by petroleum oils working its way up to the earth’s surface, where its lighter layer is blown off by the winds, leaving behind natural asphalt. This material was used up until the 1900s.
Modern asphalt contains the same durable properties as natural asphalt, with the added benefit of being processed to remove any naturally occuring mineral impurities. Nowadays, asphalt is made by mixing asphalt cement, sand, and crushed rock. The sand and rock are filtered into a drying chamber where they are then dried out. Once these have been adequately dried, liquid asphalt cement is then added into the mixture. After the materials have been mixed and heated, it is then dumped onto the road, and then raked into an even surface. Once it has been leveled out, it is then compacted by a steamroller. There are many establishments that make use of asphalt for their public utilities, such as highways, parking lots, airport runways, and playgrounds.
Asphalt paving is the popular choice for road work and parking lost because it requires about 20 percent less energy to produce and build. In addition to this, asphalt made structures take less significantly less time to construct compared to other materials.This means that if significant reconstruction is required, it can be done in a short enough span of time that civilians will not be inconvenienced by the repair work.
Asphalt is a versatile and durable material that has no end to the number of uses, which is why it is one of the best choices for your Plant City parking lot paving and road work needs.
