Sometimes, there are things that are so familiar to people that they take them for granted—that they do not bother about how that thing has come to existence. That is understandable, but if you have the time for such musing, it will help you become more informed about the world.
Roads may be a pedestrian subject to talk about. You are driving or treading on it, but have you ever wondered how it is made? If this query is getting quite interesting to you, this article has got you covered.
Below are the streamlined explanations behind the design and engineering of roads.
On Planning and Design
Under this phase, the government and the contractors plan the feasibility of building a new road. Specific considerations are taken into account: location, traffic volume, the possible number of pedestrians, and future buildings and expansion efforts. The design of the road will heavily depend on the type of terrain to be worked on. This is also where the bidding of contractors, such as engineers and equipment hire, happens.
Preparing the terrain is crucial to the building of the road. Typically, roads have three layers, which include the base, the middle, and the pavement. The base is generally compacted to provide stability. Additional soil and rock materials are added on top of it. And when the two layers are compact and steady enough, they will be then paved.
Roads also need to be efficient and effective. Additional functions are added to them, such as drainage and cat’s eyes. Other than these, signs and lightings are set up to guide motorists and pedestrians.
Road design and engineering may sound complicated to some, but it all boils down to three core components. The next time you drive, you will appreciate how the road you are on has come into being.
