Pavers are used generally in road construction. It is used to lay asphalt on the road and it is basically needed for bigger areas to work on. Large freeways are often paved with concrete and this is done using a slip form paver. Trucks dump loads of ready-mix concrete in heaps along in front of this machine and then the slip form paver spreads the concrete out and levels it off using a screed.
Compactors, on the other hand, are mechanism used to reduce the size of waste material or soil through compaction. Different compactors are used in scrap metal processing, the most familiar being the car crusher. Normally powered by hydraulics, compactors vary in shapes and sizes. For example, a large bulldozer with spiked wheels called a landfill compactor is used to drive over waste deposited by waste collection vehicles.
Compactors have different uses according to how it is needed. They are good for residential usage, municipality usage and for the construction industry.
Below here are some companies and brands that excel in their paving and compacting products:
Dynapac was founded in Stockholm, Sweden in 1934. It launched the first vibratory plate compactor in 1947. Now, it has branches and factories in Wardenburg, Germany, Karlskrona-Sweden, Tianjin-China, Nasik-India, Sorocaba-Brazil and Garland-USA.
Dynapac CA Series Compactors are fifth generation CA2500 through CA4000 single-drum vibratory rollers. They can be equipped with multiple levels of compaction controls. Loss of traction can be counteracted with a toggling gear shifting system or with optional passive anti-spin traction system. Its controls can be paired with its Intelligent Compaction solution, the Compaction Analyzer.
Dynapac’s next-generation F1000 GEN 2 Series Asphalt Pavers are wheel mounted versions and are also available in track mounted ones. They are incorporated with numerous new design features, including enhanced electronic control, undercarriage refinement, and advancements in operator comfort and machine serviceability.
Compared with predecessor models, the new GEN 2 Series models provide enhanced visibility, with a platform height of 78 inches and a deck height of 63 inches. The low-height design is aimed at providing full visibility to all working areas around the machine, and a low center of gravity, says the company, provides balance between the paver and screed to deliver accurate edge geometry and the best mat quality.
Now Famous for their high end car models, Volvo is a Swedish multinational manufacturing company headquartered in Gothenburg, Sweden. They have a wide selection of products ranging from Volvo Trucks, Mack Trucks, Renault Trucks and UV Trucks. Volvo provides transportation related products and services with focus on quality, safety and environmental care. Founded more than 80 years ago, a solid position and reputation worldwide has been built up over the decades.
Volvo released a series of compactor models which are Volvo DD110B, DD120B and DD140B double-drum Compactors. According to Volvo, These have eight dual amplitude settings for adjusting drum forces when material depth changes, then automatically match that setting with an ideal frequency. Their vibration automatically engages or disengages when pre-set speed thresholds are reached. However, these compactors have a several differences in their specifications.
