5 Types of Road Construction

What are the Road Building Materials? What are the types of Road Construction? What are White ToppingRoads? What is a Polymer Fiber Reinforced Concrete Road? 

There is a requirement for smarter methods of road construction. The aim should be to build durable and cost-benefit roads. A few unique types of road construction methods and procedures have advanced consistently. Now, we have more options for the materials used in road construction. This article will help you understand different types of road construction. Also, you will learn about road building materials.

Materials used in Road Construction?

The surface materials used in road construction are generally subject to traffic volume, weight, and weather conditions. There is a powerful urge to advance the utilization of materials for road construction and look for advanced materials that are less expensive better performing, and less harmful to the environment. However, some road building materials are soil, stone aggregates, bitumen materials, tar, and cement. (Also read 8 Facts about Cracks in Sidewalk)

5 Types of Road Construction

There are 5 different types of road construction, which are listed below:

1. White Topping Road

White topping covers existing asphalt pavement with a layer of Portland cement.

  • This type of construction depends on the thickness of the concrete layer and regardless of whether the layer is clung to the asphalt substrate.
  • The main aim is either to reestablish or expand the heap conveying capacity or both of the current pavement.
  • In accomplishing this goal, overlays likewise reestablish the ride-ability of the current pavements that have endured rutting and distortions and improve different imperfections like loss of texture. (See What is a Flight of Stairs?)

2. Polymer Fiber Reinforced Concrete Road

Polymeric fibers are being used now due to their no erosion and pocket-friendly nature. Polymeric fibers ordinarily used are either polyester or polypropylene.

Many pavement constructions use FRC material innovation, including highways, neighborhood roads, crossing points, parking areas, transport pads, footpaths, driveways, bridges, pavement overlays, modern floors, runway pavement, and patches. (See Why did they built the Brooklyn Bridge?)

3. Bituminous Road

Bituminous surface treatment (BST) or chip seal is one of the types of road construction for roads with low traffic and is used to coat and restore asphalt concrete pavement.

  • It, by and large, comprises a total spread over a splashed asphalt emulsion or cut-back asphalt cement. It is then installed into the asphalt by moving it with a tired elastic roller.
  • This kind of surface is depicted by a wide assortment of chip seals, tar and chip, oil and stone, seal coat, splashed seal or surface dressing, or just bitumen.
  • These are set down using a particular and restrictive tool. They are most frequently utilized in metropolitan regions where the harshness and loss of stone related to chip seals are less. (See What Is the Average Garage Door Size?)

4. Composite Pavement Road

Composite pavement joins a portland cement sublayer with an asphalt. They are generally used to restore existing roads rather than construct new ones. Asphalt overlays are now laid over cement to reestablish a smooth, wearing surface.

Geosynthetics can be utilized for brake control. With break and seat processes, significant weight is dropped on the concrete to incite breaking. Then, a heavy roller is utilized to situate the resultant pieces into the sub-base. (See Why Was Angkor Wat Built?)

5. Gravel Road

Applying gravel, or metalling, has had two particular utilization in surfacing the road. (See What is the Standard Door Size?)

  • First, the road course would be burrowed down several feet, and, contingent upon nearby circumstances, where French drains could be added.
  • Then, huge stones are put and compacted, trailed by progressive layers of smaller stones, until the road surface is made out of little stones which are compacted into a hard and strong surface.
  • Road metal later turned into stone chippings, is blended in with tar to shape the road surfacing material tarmac. The choice to pave a gravel road regularly depends on traffic volume.
  • It has been observed that the costs to maintain the gravel is higher than the paved or surface-treated road, especially when traffic volumes surpass 200 vehicles each day. (See How Cranes Work)
