Paving trains accelerate road construction

Home Uncategorised Paving trains accelerate road construction

SOUTH Africa’s largest multi-franchise equipment supplier ELB Equipment, has moved speedily to supply machines needed to uplift the country’s road infrastructure as much anticipated funds are released by government to complete a plethora of projects.

At the forefront of its offering are the pavers, compactors and rollers from global leader Ammann, which are used together in combination as hyper-efficient paving trains to surface, compact and finish roads to exact specifications using the latest technology in road construction. The Ammann paving trains can cut road construction times considerably and are able to provide higher quality surfaces than traditional methods.

ELB Equipment’s road and compaction equipment specialist, Craig Shappard, says that the company works with the country’s leading road construction contractors and is ready to supply paving trains and other road construction equipment as the contracts are awarded.

“A typical Ammann configuration consists of a AFW700-3 paver, AV70X tandem roller and AP240 pneumatic roller working in tandem. With a paving speed of up to 30m per minute, it is clear to see why this paver leads the paving train lineup. In addition, it is able to pave extra wide sections with up to three metre width and deep runs of up to 300mm deep.

It also allows either electric or gas heating of the screeds depending on the requirements.
“With its advanced Pavemanager 2.0 control automated paving system the paver is able to constantly monitor the process and provides feedback to operators. It also controls many key functions for precise results. Some other features include:

  • CAN-based control system
  • Connected both to the main operator control and to the screed remote control panels
  • Full overview of the complete paving process
  • Automatic programming of slope and / or crowning
  • Constant operator feedback
  • Saves and loads paving parameters for each layer (memory function)
  • Automatic levelling system
  • Offers colour displays and intuitive menus and functions on both, the main dashboard and the remote controls

Similarly, the screeds provide infinite settings with concentric flexilevers for rapid and automatic changes in the angle of attack. Efficient side shield controls can be operated from behind the screed with a single crank for safety purposes.

High compaction screeds for thick layers and roller compacted concrete can also be used. The powerful machines are available in either 4- or 6-wheel drive depending on traction requirements.

In the most common configuration of the paving train, the paver is followed by an Ammann AV70X articulated tandem roller. This combines drum dimensions, frequencies and amplitudes to deliver optimum compaction results. The roller has two frames connected by an oscillating joint that enables crab steering on each side. The crab steering provides increased compaction output and responsiveness, which is crucial on any job site.

A unique propulsion system drives the roller and the powertrain is situated in the rear frame with independent pumps for drive and vibration which provides optimal traction and compaction force.
