Making of pavement is an idea that originated several years ago. The material that is used for the purpose of making pavements is referred to as asphalt. Asphalt is used to make pavement for a wide range of surfaces, including sidewalks, parking lots, bike paths, driveways, and roads among many others. This material is suitable for this function because it can be used to place a smooth layer. Here are facts regarding Asphalt Paving.
Asphalt also has another advantage that makes it very suitable, that it, it is inexpensive. This material is used very heavily in making roads. As such, if it was expensive, then the whole process of laying pavement would be very expensive. Apart from not being expensive, the material is also very durable. If it is laid appropriately, it can stay in good condition for several decades.
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.
Bitumen was discovered by ancient people who used it for a wide range of uses. Mostly, they used it for waterproofing purposes. These people used bitumen to seal containers that they used to store water. Also, they used the material to make their watercrafts waterproof so that they could venture into water bodies. Old civilizations such as the Roman Empire also used this material to make roads over short distances.
Asphalt should be used when it is still hot since it is existent in liquid form at a specific temperature. The liquid binder can easily get poured out and spread when it is hot. After being poured out, it is rolled and finally compacted to form a durable smooth surface. Asphalt normally moves if it is exposed to a heavy luggage hence it is viewed as flexible pavement.
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.
Pavements are usually built for three major reasons, that is, load support, drainage, and smoothness. Bitumen is a very stiff material and when it is mixed with crushed rock, it becomes even stiffer. As such, it helps other materials used to make roads to be able to resist loads much better. With asphalt, roads are able to withstand the pressure of loads without undergoing too much deformation.
Asphalt also provides a better degree of water impermeability. As a result, it is effective at draining any surface water that falls on it. Nevertheless, to achieve good drainage, better geometric design should be incorporated into the construction of the pavement. Finally, comfort is enhanced by the smoothness which the pavement material provides and it also reduces the operation cost of vehicles.
