Were you a fan of those little toy road kits when you were younger? Maybe you had the Hot Wheels craze like a million other kids all over the world. Some people are still fans of the old school toy cars over the RC cars of today. Well, either way you probably took them for a spin on the road, or on the nearby beach after building a nice makeshift road for your vehicles to thunder down. Now, toy roads are easy to make and easy to break. The real deal is a whole different story altogether. While you may only have needed yourself and a plastic shovel to build your toy road, the reality of building roads is that it is done on a much larger scale in the real world, and it requires a huge amount of money, planning and equipment to get a good road built within deadlines.
This is the first thing that road building contractors do when they have been hired to begin construction of a new highway or B-class road. There are a lot of people involved in this phase, mainly civil engineers and experts in the field as well as a representative from the city planning department. The type of road needs to be determined, as well as the materials used. All of this is determined from surveys and estimates as to the amount of traffic over time that the new road will see. In addition to this, the TYPE of traffic going down the road is also used. Planning phases usually take a few months to be done right, and it takes even longer for a more complicated road with overpasses and other structural features. Sometimes, a really major road can take a few years of planning before construction even begins.
The actual construction begins after the plans have been finalized and road building contractors have been hired and briefed. The construction phase is done on a massive scale. The time it will take depends on the length of the roads, the materials used to make it, the scale of the operation and the budget, and can take anywhere from a couple of weeks for smaller country roads to a few years for a highway complete with bridges and interchanges.
From the initial earthwork and foundation phase to the final laying of the top coat on the roads, each part is meticulously planned and carried out. Mistakes are made, but they are detected and rectified before the next part of the construction even begins.
