In addition to asphalt pavers, paving equipment includes cold planers, asphalt trucks, and material transfer vehicles. These heavy machines are extremely productive and easy to maneuver. You can also choose from seal coaters and water tanks. Each one has a different function. Here is a brief overview of each one. All of these machines are important to paving jobs. If you’re planning to use one of these machines, here’s a look at the different types of equipment available.
There are various sizes of asphalt pavers available, with the horsepower ranging from three to twenty horsepower for smaller, towed models, to one hundred and twenty-five horsepower for larger self-propelled machines. Most asphalt pavers run on diesel fuel, which is also used by many other types of construction equipment. These machines have dual control stations and can pivot at two points for better visibility. They have a hopper that holds up to two cubic yards of asphalt, and they can be adjusted from the front or rear to fit the width of the road.
Tracked and wheeled asphalt pavers are made of steel. They have a heavy-gauge steel mainframe and a feeding system with forged steel sections. The tractor tows a screed that shapes and levels the asphalt. It has components that include vibrators, endplates, and slope sensors. The engine cover is steel. The tractor and the screed are typically made of the same type of materials.
A wheeled asphalt paver is a mobile machine that has two large wheels under the cab and two, four, or more smaller wheels at the front. It provides excellent mobility throughout the job site. Wheeled equipment is often preferred for projects with long stretches of asphalt, since it is more flexible and can cover a wider area than tracked equipment. Moreover, wheeled equipment is also ideal for paving existing asphalt surfaces. This equipment is also great for milling, overlaying, and filling.
The cost of cold planers can be quite high, especially if they have to be refurbished. Depending on the machine, it can cost up to $30k to refurbish. The basic wear parts of cold planers are the conveyor assembly and the cutting drum. You’ll also have to pay for engines, hydraulics and undercarriage work. Used machines are usually worth 20-30% less than brand-new ones.
The cold planer head is similar to that of a drill, with teeth on a rotating disc. This feature allows the operator to precisely control the depth of the cuts, removing both the upper and lower layers of road. Unlike a drill, cold planers can remove a layer of material without emitting any emissions. This process results in a smooth surface that is free of imperfections. Cold planers are an excellent choice for any paving job, as they have a wide variety of uses.
In addition to the cold planer’s versatility, cold paving equipment can be used to remove concrete or pavement. These materials require robust equipment to remove them. A Cat(r) machine is the ideal choice for cold planers in Nevada. Cold planers are available from Cashman Equipment. Their inventory also includes a wide range of other paving equipment, including sandblasters, grinders, jackhammers, and more.
Material Transfer Vehicles
A material transfer vehicle is a self-propelled paving equipment that moves asphalt from a truck to a paved area. The materials are transported via a conveyor attached to the frame of the vehicle and are placed in an asphalt surge bin. A conveyor on the surge bin is designed to quickly discharge truckloads of asphalt into the hopper of the paving equipment. The surge bin has a discharge opening on the rear side. A truck-unloading conveyor is located adjacent to the front end of the surge bin.
These vehicles provide unique advantages for asphalt pavement construction. Their low weight and mobility greatly reduce trucking costs. A material transfer vehicle may even be smaller than a typical haul truck. ASTEC offers two models of material transfer vehicles to meet paving contractor needs. These vehicles may be more compact, offer improved maneuverability, or feature improved asphalt-mixing capabilities. If you are interested in learning more about material transfer vehicles, read on.
The Vogele MT 3000-2i material transfer vehicle delivers superior performance in asphalt paving. The MT 3000-2i weighs 56,000 pounds and has an 18-ton storage capacity. Its low center of gravity makes it easier to maneuver and is also equipped with exclusive innovations. The MT 3000-2i material transfer vehicle offers an excellent combination of capacity and speed. You’ll be glad you chose this model.
Asphalt trucks are important pieces of equipment in a pavement project. They transport the hot asphalt from the plant to the site. They are also used to sweep road debris that could potentially damage cars. These trucks have various features, including bottom dumps and end dumps. Live bottom trucks can also unload their payload by using a conveyor belt. The front end lifts and lowers, while the bottom is designed to release its load from under the truck.
The wheels of wheeled or tracked asphalt pavers make them easier to maneuver around the construction site. These machines have hydraulic drives and receive hoppers that contain the asphalt. They also have distribution augers and feeder conveyors. A screed is also an important piece of equipment in the construction process. Its width and weight must be large enough to create a smooth layer of asphalt. Some types of asphalt pavers also have a lighting package and sensors to adjust the slope or grade of the surface.
Self-propelled pavers are typically about 19 to 23 feet (5.8-7.0 m) long and ten feet wide. They weigh between 20,000 and 40,000 lb (9,090-18,180 kg) and depend on the engine size and type of drive system. Depending on the model, these vehicles can plow a surface that is approximately an inch or two thick. If the paving project is more than a few feet wide and is only a few feet deep, these machines may not be the right choice for you.
Smooth Drum Compactors
Smooth drum compactors are popular choices for paving operations. These machines feature drums of varying widths ranging from 42 to 84 inches. They can be pneumatic or static, and some come with a double drum. Volvo rents compactors up to 7.5 tons, and their dealers offer the rest of their compaction line. These machines are designed to work in all kinds of terrain and provide a smooth finish.
Grid rollers are made of steel bars and form a grid pattern on the steel drum. They may have concrete blocks or steel attachments. They are generally pulled by a tractor or other heavy machinery, and they produce high contact pressure without kneading the material. These machines are most effective on well-graded soils and subgrade roads. These machines can also be used on hard surfaces. However, they do not handle the unevenness of concrete and asphalt.
Double drum rollers can be used for paving jobs. They have two drums on each end, one at the front and one at the rear. Single drum rollers are better for narrow areas or sharp turns. Double drum rollers are better suited for paving projects or asphalt compaction. However, they do not have tires, which makes them less stable and do not offer traction. Lastly, there is a third type of double drum roller, which implements manipulative force and kneading to compact the material. Serrated rollers can compress materials deeper into the soil, while double drum rollers are designed to provide a more aggressive punch.
Asphalt sweepers are important paving equipment that help make roads look their best. They are used to clean excess road debris to make the pavement easier to resurface after a snow or ice storm. Sweepers should be carefully maintained to avoid damage to the paving material. Asphalt paving machines undergo a lot of wear and tear during the paving process. The machine loads hot asphalt onto the road surface and compresses it.
ProSweep operators are professional paving and milling contractors who have vast experience in the industry. These operators stay in constant contact with the job crew. They are able to handle high volumes of heavy materials and fine particles. Moreover, their vehicles are equipped with hydraulic-driven systems to reduce the risk of overspreading or damaging asphalt surfaces. For this reason, they can also sweep a large area quickly and efficiently.
After milling, sweepers clean up the road surface. Debris, small rocks, and other materials on the road surface prevent proper bonding between asphalt and base course. Also, they reduce the chances of uneven compaction of asphalt, which can lead to poor road safety. Small pebbles and rocks can also fly up and hit windshields of oncoming vehicles. To avoid this problem, sweepers have internal walls that slope to guide the payload out of the opened gates.
Hot Oil Tank Trucks
Asphalt distribution and paving equipment include hot oil tank trucks and distributors. These types of equipment are mainly composed of a truck chassis, insulated asphalt tank, automatic-control heating and spraying system, and tire carrier. They are suitable for distributing various kinds of asphalt materials. You can see these pieces of equipment in action in construction sites. But what makes them unique? Read on to learn more.
