Road construction machines are some of the most powerful apparatus ever invented by humans. These machines are mainly used for construction of new highways, or re-carpeting of old roads.
Here are the most powerful road construction equipment:
- Motor Grader:
Commonly referred to as road grader or a maintainer, motor grader is an equipment used to create flat surfaces for asphalt to be placed on.
Common models consist of three axles, with the engine and cab located above the rear axles at the back end of the vehicle and a third axle at the front of the vehicle – with a long blade in between.
- 2. Asphalt Mixing Plant
asphalt plant is an important road construction machinery used for the manufacture of asphalt concrete and other forms of coated road-stone used in road construction projects.
It combines mineral aggregates, sand and a filler – in correct proportions, heats the mixture and then coats it with a binder.
The plant then keeps the final product heated to avoid setting before the product is laid down in layers.
- 3 .Road Roller Machine
Also known as roller-compactor, a road roller is one of the most important road construction machines. Due to its importance, a road roller is a common feature on road construction sites.
A roller is basically a compactor type engineering vehicle that is mainly used to press down soil, gravel, concrete, or asphalt in the construction of highways and foundations.
Rollers can be rubber tire rollers, double-drum asphalt rollers or combination rollers and the type of roller used is determined by the mixture used in a road project.
There are various types of rollers used in compaction works with the choice depending on the job and material to be compressed. They include smooth wheeled roller, vibratory roller, sheepsfoot roller, and pneumatic tyred roller.
- 4 .Crawler Excavator
Also referred to as diggers, excavators are heavy construction equipment used for excavating earth and rocks and loading them onto a dump trucks.
Excavators consist of a boom, bucket and cab on a rotating platform located above an undercarriage with wheels or tracks. These machines are capable of performing a wide range of work by changing front attachment.
- 5 .Forklift Truck
Also known as fork truck or lift truck, a forklift is a powered industrial vehicle with an attached platform that can be lowered to pick an object on or below the ground and raised to move the object.
A forklift was initially used to move objects in factories but the design has been modified over the years to increase its uses as an important road construction equipment.
6.) Wheel Loader
A wheel loader, also referred to as front loader, skip loader or bucket loader, is a type of tractor used to move a pile of material from the ground and load it onto a truck or into an open pit.
It consists of a front-mounted square wide bucket joined to the end of two arms used to scoop up materials from the ground without spreading it out.
7.) Truck Crane
Truck cranes are important road construction machines. These cranes are usually mounted on the back of a lorry to assist with lifting requirements within a road construction site.
They consist of the carrier (called the lower) and lifting component (called the upper), which are joined through a turntable allowing the lifting component to swing from side to side.
Truck cranes are usually compact, fold up, and require negligible mounting space.
