What is call road? A road is a broad way, or way on land between two places, which allows travel by people and transportation vehicles. We walk on the road everyday. Or ride in a vehicle walking on the road. How does the road built? Do you have any idea about road construction?
Road construction, which requires the creation of a continuous right-of-way, needs to overcome different geographic problems and has grades low enough to permit vehicle or foot travel. It may be required to meet standards set by law or official guidelines. How does it begin? The process is often begun with the removal of earth and rock by digging or blasting, construction of embankments, bridges and tunnels, and removal of vegetation, followed by the laying of pavement material. After design, approval, planning, the legal and environmental considerations have been brought to surveyors' mind. Roads are designed and built primarily for vehicular and pedestrian traffic use. The major concern must be storm drainage and environmental considerations. So, as we can see, road building is not a simple work, and a variety of road building equipment is employed to help in road building.
There is a kind of equipment called the road grader http://www.ecvv.com/company/chinawbest/products.html, which is also referred to a grader, a blade, a maintainer, or a motor grader. It is a construction machine with a long blade used to create a flat surface. Typical models have three axles, with the engine and cab situated above the rear axles at one end of the vehicle and a third axle at the front end of the vehicle, with the blade in between.
In some countries, for example in Finland, almost every grader is equipped with a second blade that is placed in front of the front axle. Some construction people even refer to the entire machine as "the blade." In road construction, the grader is used to finish grade or the rough grading, performed by heavy equipment or some engineering vehicles such as bulldozers and scrapers. Graders can be used to produce inclined surfaces, to give cant to roads. Also, they are used to produce drainage ditches in some countries, with shallow V-shaped cross-sections on either side of highways.
Usually, road graders are used to set native soil foundation pads to finish grade before the construction of large buildings. At the same time, graders are commonly used in the construction and maintenance of dirt roads and gravel roads. In the construction of paved roads they are used to prepare the base course to create a wide flat surface.
Graders are often used in municipal and residential snow removal in some countries like Northern Europe, Canada, and the United States. In scrubland and grassland areas of Australia and Africa, graders are often an essential piece of equipment on ranches, large farms, and plantations to make dirt tracks where the absence of rocks and trees means bulldozers are not required.
The grader-style vehicles are often equiped with a sweeper attachment. Some graders can operate multiple attachments, or be used for separate tasks like underground mining. In conclusion, every time before there is a road, there must be the road construction. Many construction equipments will take part in the building process.
