In the current scenario or era, where communication and connectivity is the key element for the globe to stay in touch with every corner of the world, roads play a very important role in this purpose. With increasing population, the need for construction of new roads is also increasing day by day. Hence, to meet with the requirement, heavy construction equipment for the construction of roads is also increasing every day.

Technological advancements have given birth to different kinds of machines, tools and engines as well as heavy construction equipment. They all serve different purposes and are used during different needs. Hence, depending on the type of construction that you are catering to, you need to choose the type of heavy construction equipment. Here is a list of all the most important ones that you might require during the construction of the road.

  • Crawler and Excavator:

 

Before the construction task is started, the area needs to be excavated and the load of dump needs to be removed and the loader and excavator help in this task. It can dig the earth and remove the rocks and earth from the area. These usually have a bucket, a boom and a cab. They can have either tracks or wheels, depending on the requirement and surface that it needs to work on.

  • Motor Grader:

 

The first step of road construction is creating a flat surface, suitable for the spreading of asphalt. To create that surface, you need a motor grader. The usual structure of the motor grader has –

  • Two rear axles at the back
  • The cab and engine located above
  • One axle in the front of the vehicle
  • A long blade in between the front and rear axles.

The motor graders are also commonly known as a maintainer.

  • Chip Spreader:

 

Once the surface is prepared, the chip spreader spreads the bitumen or asphalt on the surface. They come in different shapes and sizes. The asphalt that is mixed in a permanent or temporary asphalt plant is spread by the chip spreader.

  • Road Roller:

 

As the chips, bitumen or asphalt is spread on the surface, the road roller presses it down into the place. There are different types of road rollers like –

  • Double drum asphalt rollers
  • Rubber tire rollers
  • A combination of both
  • Pneumatic tired rollers.

As the material that needs to be rolled or compacted in case of a road construction is either of asphalt, gravel, concrete or soil vibratory steel drum rollers or padded drum compactors are used for this task.

These are some of the very basics of the heavy construction equipment that are required for the construction of roads. The type of road that needs to be constructed, the type of surface, the area and the engineering plan would decide the types of equipment or machinery that would be required. Along with the heavy equipment, there is always the requirement of various tools, drills and mixing machines, without which the construction of the roads would never be possible.

Smooth roads are generally the bi-product of good rollers and other raw materials that are needed for constructing roads. We all understand the importance of good roads to the overall development of the country and at the same time how convenient it can make our lives. We all have experienced bumpy rides at some or the other point of time in our lives and the jerks that we get weakens the spine and eventually can cause lot of health related issues. Other than health, it makes the entire journey so very time consuming and uncomfortable that we may think twice to wander again in that zone. Since we all understand the importance of good roads, we should also give equal importance to the equipment and materials that are required to make good roads. Good quality heavy equipment is nothing but the kind of technology you put to construct quality roads.

So when we speak about quality roads, there is heavy equipment whose mention in the journey of the entire construction of roads is of utmost importance and it is none other than a road roller. Now road rollers are of several types and the utility of any types depends mostly on the kind of soil on which it has to work on. So it is not necessary that the one you see on big roads are also to be used on the lane that you have your house on. You may use a different kind of a roller to construct or repair the nearby lane.

For constructing big roads, smooth wheeled rollers are ideally used. Now these smooth wheeled rollers are of two types. The first one is a static smooth wheeled roller and the other is the vibrating smooth wheeled roller. These rollers are basically used in road construction where the soil is rough and it needs to be crushed. Soil like gravel, crushed rock, asphalt etc. need smooth wheeled rollers. Being rough, these soil do not require great pressure for compaction and the rollers are needed to give a finishing touch to the outer surface of the road. The most important component in the smooth wheeled roller is the drum that is attached to the front of the machine. The performance of the smooth wheeled roller depends upon the load per cm width which gets transferred to the soil and also the diameter of the drum.

For improving the performance of the roller, one can simply increase it weight by changing the drum from a lighter to a heavier one. Many operators do not change the drum to increase its weight but they fill in wet sand or water in the existing drum and make it heavier. They ultimately get what they need and therefore do not have to keep on changing the drum in order to make it heavier. While you are rolling the roller on the road, you should be immensely careful with the speed of the machine as it should not be more than 4-6 km per hour or else you will not get the desired result. Keeping it slow sounds to be the best way out.

If you have ever been to a construction site, you must have noticed that along with the debris, brick and mortar, the site is always filled with a variety of machines loading and unloading stuff, moving things here and there and the like. Well, this machine, known as heavy construction equipment forms one of the most important part of the entire construction business. And pneumatic rollers are one of those equipments that form an indispensible part when it comes to the road construction arena.

What Is Pneumatic Tyre Roller?

Pneumatic tyre rollers are important for the construction industry. But what exactly is the pneumatic tire roller? Well, pneumatic tire rollers are a kind of heavy equipment that is specifically used in the road construction industry. It is used for the purpose of paving asphalt on the roads for achieving a smooth finishing touch.

The next area that needs to be looked at is exactly what purpose does the pneumatic roller serve in the construction of roads. The pneumatic roller serves as an important tool for the compaction of paved asphalt in the construction of roads. The other variations of the road rollers such as the steel drum rollers also prove to be quite handy in the initial phase, but the problem lies in the fact that they also bridge some of the spaces of the asphalt mat that is being laid. The pneumatic rollers on the other hand, blend the “hot mix asphalt”, by operating all of the nine oscillating tires in the asphalt mat. Along with achieving a greater compaction density, it also ensures that the bigger aggregate of the mix down settles at the bottom and the finer aggregate come at the top. This ensures that the asphalt is sealed properly, thereby, removing voids and preventing the intrusion of water. And this in turn ensures that the road that is being paved lasts longer.

Pneumatic rollers are used to accomplish every paving job. Their use in the road construction industry for the purpose of attaining a greater compaction density and ensuring the longevity of the constructed road is undeniably important. Hence, in order to attain a surface that is smooth and durable, it is necessary to make use of the pneumatic roller.

 

Purchasing a Pneumatic Roller

Constructing a road? Then, there can be no doubt about the fact that pneumatic road rollers will function as an important tool in the entire affair. Before settling on a deal with regard to rubber tire rollers, you have to keep certain things in mind. For one, the asphalt mix that is to be used contributes significantly to the kind of pneumatic roller that you are about to purchase. Also the kind of project that you are handling along with the equipment that you are using also governs the choice of your pneumatic rollers.

It is a widely acknowledged fact that the pneumatic roller has become an indispensible part of the road construction industry. There can be no doubt about the fact that this kind of roller does have an upper hand than the others in the road construction industry.

Construction of roads is an ardent task for both the government and the one who has taken the job. Companies given the job to construct roads need to have all sorts of heavy equipments available with them as heavy equipment has its own significance in road construction and without them it’s pretty unimaginable to even move a stone from one place to the other. We need a bulldozer to level the land or an excavator to excavate the land, remove the waste mud from the place and then level the land. Then we may also require a loader to take off the snow from the land or if it used to construct a road in mid of a forest, then it can be used to carry the logs and ferry it from once place to the other. Therefore, each machine has its own significance in this purpose and the absence of any of the machine can severely impact the entire project.

The construction company needs to have a thorough knowledge on how things work in this domain. Any previous experience in constructing roads will always work as an added advantage to them. We would be discussing in brief about the role than heavy equipments play towards the construction of roads in US.

Hydraulic excavators:-  These are used to excavate earth and remove the unwanted mud from the face of the earth and dump it in a truck. It’s not only used to excavate earth but also used to remove huge blocks of stone, logs lying on the ground and things which are unwanted and needs to be dumped. With the help of the shovel, it takes up the stuff from the earth and put it in the truck which then ferries them in the dump yard.

Bulldozers:-  Bulldozers are ideally used to level the land. They have those heavy rollers in their front which is used to crush every particle that’s in its way and mixes it with the layer of the earth. Bulldozers are seen in many road construction sites rolling the tar on the road and make the surface smooth as ever.

Loaders:-  This is another important heavy equipment which is widely used during construction of roads. Especially places which have the surface covered with snow, the loaders are extensively used to load the snow in the bucket and ferry it to the truck. Many construction companies are using hydraulic loaders which give them high power, more efficiency and low fuel consumption.

Articulated trucks:-  When we talk about construction of roads, articulated trucks plays a significant role in getting the work done quickly. The heavy equipments take off the unwanted materials. However, that is loaded on the truck which eventually ferries the stuff to the dump yard or which is on the same job site. Without these trucks, life would have been very difficult for the construction companies and thus considered as important equipment.

Companies that manufacture heavy equipments are Caterpillar, John Deere, Hitachi, Volvo etc. Roads bridge the gap between 2 cities and are very imperative as far as the growth of the nation is considered.
