The idea of pavement making was started many years back. Asphalt is the material used to make pavements. Asphalt is normally used in making pavements for a variety of surfaces such as driveways, bike paths, sidewalks, roads, and parking lots among others. Asphalt is a very suitable paving material because it achieves a smooth layer. This is what Asphalt Paving is all about.
Another advantage that asphalt has that makes it suitable is that it is very inexpensive. Given the scale on which the material is used to make roads, it would be a very expensive affair to lay pavement if the material was expensive. Besides being inexpensive, this material is also very durable. Provided that the material is laid properly, it can last for several decades without getting damaged.
The material employed in pavement making is normally made up of a mixture of liquid asphalt binder and crushed rock. This binder is a naturally occurring material that is derived from the environment. The word bitumen is often used in place of the word binder. It is a petroleum product that resembles tar. In addition, it looks like pancake syrup that has been hard dried.
The ancient people discovered bitumen and used it for a wide variety of functions. Most of the time, it was used for purposes of waterproofing. The ancient people used bitumen in sealing water storage containers. They also used the material for making watercrafts waterproof so that they could use them in water. The Roman Empire and other old civilizations used bitumen in road construction over short distances.
Asphalt is has to be used while still hot because it exists as a liquid at a certain temperature. The hot liquid binder can therefore be poured easily before being spread, rolled, and compacted to make a smooth durable surface. Asphalt is usually considered as a flexible pavement because it actually moves when it is subjected to a heavy load.
However, with proper design, the material needs to have the capacity to regain its initial shape after removal of the load. The capacity of asphalt to regain its initial shape is determined by the duration that it is subjected to the heavy load. In the event the load stays in one spot for a long time, the pavement may be unable to regain its initial shape. In addition, asphalt is regarded as viscoelastic in the sense that it is viscous and elastic simultaneously.
Drainage, load support, and smoothness are the three main reasons behind building of pavements using asphalt. Bitumen is normally stiff and if crushed rock is mixed with it, its stiffness increases. Because of this, it aids other materials used in road construction to have the ability to resist loads better. When roads are made using asphalt, they can withstand pressure from loads without being much deformed.
Secondly, asphalt offers a good level of water impermeability. As such, it can help to effectively drain any surface water that falls on it. However, good geometric design must also be incorporated into the pavement to achieve better drainage. Lastly, smoothness that pavement material offers enhances comfort and reduces vehicle operation costs.
