Asphalt is used to form a hard surface over a designated area. Typically used as a surface for roads, car parks and driveways, using asphalt over alternative materials has many advantages. Read on to find out more about asphalt
What is Asphalt Made Of?
Asphalt is a thick black or brownish substance acquired from crude oil – the same oil that is used to make gasoline, vinyl and kerosene. Asphalt gets scrapped from the oil barrel’s bottom once all the other petroleum-based items have undergone processing or refining. The black color of asphalt is due to its 80 percent carbon composition. Along with a few other trace minerals, asphalt also has sulfur. Asphalt is commonly used as a rooftop sealant and serves as a durable mat for airport runways, roads, parking lots and playgrounds. The crude oil tar is basically mixed with gravel or sand to form asphalt.
Benefits of Asphalt
Asphalt has various utilities and it has continuously been in use for decades due to the following:
Asphalt gives roads the smoothness required to drive/ride on them sans bumps and inundations. Applied in multiple layers, asphalt helps eliminate repetitive construction joints, blow ups and noisy surface texture. As a result, asphalt is commonly used in airports as well. Runways made from asphalt offer safer take offs and landings, since the layout is quite smooth and also easy to maintain.
Asphalt has a long shelf life and also the initial installation costs are quite low. And thanks to the material’s recyclability, asphalt’s residual value is much higher compared to other pavement materials. The asphalt used could be fresh or reclaimed from already used fixtures. Despite being used, reclaimed asphalt is no lesser in quality and durability than new asphalt.
Newer technologies have rendered a significant spike in asphalt’s ability to disperse and drain surface water, thereby decreasing water spray and enhancing driver visibility during wet weather conditions. This also means road markings become more visible from a distance.
There are different mixtures and types of asphalt available, each having qualities tailored for particular applications. For instance, there are asphalt mixtures that facilitate swift draining of heavy rain. Some mixtures can also be designed to acquire a particular texture, to increase skid resistance during hard or sudden braking. Asphalt can also be coloured to alert drivers of dangerous spots, such as sharp bends or hidden junctions.
Asphalt roads have thick bases to withstand moving vehicle load. The base is covered by a binder course, which is usually 30 to 40 millimetres in thickness. Based on the type of asphalt mixture being used, this binder course can stay put for almost a couple of decades.
Quick to Construct
Asphalt doesn’t require time to cure or heal. Motorists are free to use the newly laid asphalt right after the roller exits the construction spot. This only means there’s less inconvenience caused whenever and wherever an asphalt project is in place.
