4 Major Phases In A Road Construction Project


When it comes to commercial infrastructural projects, roads rank among the most important installations; especially in the commercial sector. Generally, roads include all kinds of professionally constructed outdoor pathways including pavements, parking lots, driveways, private access roads, and even the huge public highways. With the exception of a few specially constructed pathways for specialized transportation purposes, all other roads are basically constructed in the same way. Essentially, the materials’ constitution, the construction equipment & machinery, and even the applied technology may vary from one project to the other, but the basic procedure is pretty much the same. Although they might not necessarily be implemented in the listed order, the four steps discussed below form the most fundamental processes in road construction.


Site Planning And Preparation


It all starts with project planning and preparation. Much of the planning and preparation in Commercial Road Construction is be done by land survey teams. These professionals will map and set control lines running the entire length of the road. They will then create reference points along the shoulders, and plant markers to guide the construction crew. In order to ensure ease of site access, the contractor has to clear any vegetation and remove any other obstructions occurring within or near the allocated road allowance.


Installation Of Utilities


The next step is the installation of underground utilities like storm drains. This is a very intensive phase in the project because it involves the fitting of valves. The new piping systems are then connected to the existing drainage then redirected to the affected homes. The concrete supports of security or street lights are also planted before the actual road construction begins.


Road Building

After all the utilities are installed and tested to ensure proper functioning, the actual road construction exercise begins. The road-building phase kicks off with the placement and installation of concrete curbs, gutters, sidewalks, and even new driveways to residences. After these accessories are installed, all vehicles are barred from driving on the curbs for three days until the concrete is fully cured. In the meantime, electrical conduits for the streetlights are installed behind the new curb.

After the concrete curb is totally dry, a base layer of asphalt is laid down for the main road or pathway. The closed driveways are then restored and connected to the new road. The final layer of pavement is then placed and the paved sections marked or painted. When it comes to road painting, any certified Greenwood asphalt striping contractor will know the most appropriate styles and colors for marking the driveways, access roads, bumps, and in some cases the pavements.


Landscaping, Surface Marking, And Site Cleanup


The final step in this tedious undertaking involves the application of landscaping aesthetics and site cleanup. Landscaping efforts should start just after the first base layer of asphalt is placed; that is before the final layer of pavement is installed. Placement of top soils and of other decorative retaining bulwarks is all part of landscaping. These and other aesthetic endeavors will continue even after the site cleanup exercise is over.
