There are many types of heavy equipment involved with the making of our nation's roadways. You can see them moving along, removing asphalt, grading the ground, putting new pavement down, and making sure that the road is ready for vehicle travel. While you may not like seeing them, or having to wait for sometimes long periods of time, these machines are important. We are all very happy when they are done, not just because they are gone, but also for the smoothness of the new roadway.
Dump trucks are probably the most valuable of all the heavy equipment on a road construction job site. Not only do they haul away the old asphalt, extra dirt and debris when tearing down the existing road, they also bring in many of the materials used in road construction. Some of these include new asphalt, gravel and rock, as well as many other materials.
The next most important heavy equipment is the front end loader. These vehicles are the work horse of the construction site. They can perform a variety of different tasks. They can load the dump trucks with debris, haul smaller loads around the job site, and be used to pick up machinery that is too heavy for people. They are also used for scraping up old roadway, on sites that are too small, or difficult for a paving remover to get into.
Paving removers are a piece of heavy equipment that moves slowly along, picking up sections of roadway, breaking them up and loading them into a truck to be hauled away. They make the job of pulling up outdated asphalt roads faster and easier that a front end loader, or by hand. They also cut down on the labor force needed when it comes to this area of road construction.
Graders are an important part of road construction because they level the dirt once this layer has been applied. This piece of heavy equipment can control the height of the roadway, as well as scrape aside any extra layers. Without this machine, the road would be uneven.
Pavers are also a valuable piece of heavy equipment for making roads. They can be used to not only put down and compress the underlying layers of dirt, but also apply the asphalt to the road surfaces. While these machines move relatively slowly, without them layering and paving roads would take up to ten times as long to complete. They are precisely computer controlled instruments that are one of the most important pieces of equipment needed to complete the job.
The roller is a piece of heavy equipment that flattens and seals the asphalt layer, and makes sure that the surfaces of the roadway are smooth. It compresses the surfaces, and removes any air pockets that may have gotten trapped between the layers of materials. Without it, the expanding and contracting would create cracks and holes in the newly created road.
There are many other pieces of heavy equipment that are needed, depending on the type of road, where it is located, and the size of the project. There are concrete mixers, for making edge forms, heavy cranes that lift large steel I beams into place on over passes and bridges, as well as many others

Those equipment are really helpful on this kind of industry today. Because they fasten their work when they have this.
