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 asphalt that is used in making pavements is usually composed of a mixture of crushed rock and liquid asphalt binder. The binder is a common material that occurs naturally in the environment. Another name that is used to refer to it is bitumen. Bitumen is a petroleum product that looks like tar and closely resembles hard dried pancake syrup.
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.
At a specific temperature, asphalt occurs as a liquid. As such, it has to be utilized while hot. Thereafter, it can easily be poured prior to being rolled, spread or compacted to yield a smooth long lasting surface. Normally, asphalt is regarded as pavement that is flexible since heavy loads make it to move.
However, if the material is properly designed, it should be able to rebound to its original shape when the load is removed. However, its ability to rebound to its original shape usually depends on how long it is subjected to the load. If the load remains in place for too long, asphalt may not be able to regain its original shape. The material is also considered to be viscoelastic in that it is both elastic and viscous at the same time.
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.
