Roads design and engineering, also known as highway engineering, is a discipline of engineering that branches from civil engineering. It involves the design, planning, operation, construction, and maintenance of any tunnel, road, or bridge in order to ensure effective, safe transportation of both goods and people. While the standards of engineering roads are constantly being studied, it means that the planning and design process is also changing as time goes on. With these changes comes the need for constant understanding of those modifications, and at Cad Crowd, we have roads and design engineering freelancers who know those changes well. We can help connect you with the right freelancer for the job.
There are a number of factors that need to be taken into account when designing roads and highways. These new roads must meet all performance, service, and safety standards at once. Different topographies need to be taken into account as well. Highway geometric design is among the most important of these aspects. This sort of design primarily takes into consideration the visible parts of a highway. This also includes the social and environmental effects of the design on the infrastructure surrounding it.
Because of this, there are several design elements that have to be taken into consideration when designing a road on different topographies. These include: design traffic volume, horizontal and vertical clearances, design speed, lane width, number of lanes on the road, cross sections, levels of service, alignment, grades and super elevation, as well as sight distance.
The materials that are used for roadways also must be taken into consideration as they continue to evolve over time. The two main pavement surface types include hot mix asphalt and Portland cement concrete. These materials are layered to give support to the pavement system and these surfaces may even include the subbase layers, all of which are just as important to consider as the next. Flexible pavement, also known as asphalt, often consists of four layers. A rigid pavement design is usually used in places like major highways and airports. They are better suited for these sorts of environments.
Furthermore, a drainage system has to be considered. These systems are crucial to the success of the highways. No matter how well the other parts of the road work, if there is improper drainage, the road may not survive as long as it should. Too much water in the highway can eventually make it fail, even in minor ways that are not catastrophic but will still require plenty of time, money, and general inconvenience to fix.
