Asphalt Paver Dimensions
These machines range from 19 and 23 feet (5.8 to 7 m) lengthwise. In terms of width they are 10 feet (3 m) and 10 feet (3 m) high. The weight of these pavers ranges from 20,000 to 40,000 pounds (9,072 to 18,144 kg). The horsepower will vary per machine.
The smaller ones have between 3 to 20 horsepower. The larger units are more powerful, with horsepower around 100 to 250. Traditional asphalt pavers are towed by trucks, but the newer models are self propelled. The self propelled models are also the ones with greater horsepower.
Components of Asphalt Pavers
While the asphalt paver dimensions vary among new models, the components are almost always made of steel. Many parts are also shared by these machines. The first is the tractor. This component is used to propel the machine forward.
It is also employed for layering the asphalt. It is composed of the hydraulic drives, engine, tracks or wheels, distribution augers, feeder conveyors and the hopper for getting the asphalt. It also has numerous controls.
The screeds are used for shaping and leveling the asphalt The floating screed is equipped with controls, slope sensors, vibrators, burners, end plates and leveling arms.
The screed is towed by a tractor and connected to a thickness control. This is the component that adjusts the thickness of the asphalt. It also works as a compaction device. After he paver has done its work, the road roller will follow it up and finish the pavement work.
Tracks and Tires
There are also some asphalt pavers that are set on tires. This is used if speed is needed for the paving work. There are also pavers that move on tracks if the traction is boosted. The pavers that run on rubber tires are made up of two inflatable tires at the rear.
There are also 4 smaller tires included. For these to work, the tracks have to be constructed of rubber too. These are reinforced with cables composed of flexible steel.
The work is done at a rate of 100 to 300 ft every minute. The typical spread width is 8 and 12 feet (2.4 and 3.7 m), but it can extend up to 40 feet in some cases. These can vary depending on the asphalt paver dimensions though.
