Using pin-less technology

Contractors working on large projects which involve laying road surfaces are increasingly trying to avoid the use of steel road pins. Driving long steel and timber pins into the ground to lay road exacerbates traffic congestion, involves a great number of engineering hours and creates a dangerous environment for the workforce as workers and road-making plant are occupying the same area often simultaneously.

This company devised an innovative solution to this problem:

  • Teamed with Aggregate Industries to incorporate modern technology into the build.
  • Adopted pin-less technology across the board.
  • Used specialist telemetry software to lay the surfacing.
  • Transferred design model into guidance system, reducing setting-out errors and chance of human error.
  • This has resulted in a high-quality and accurate finished product, and a safer and less-overworked workforce.
  • Laid 13m wide and 300mm thick surfacing in a single layer with no setting out.
  • The project placed over 500,000 tonnes of pavement accident free.

The use of this technology was safer and ensured the work was done faster and with less disruption to road users. Their success was recognised, as the project team won the ‘Application of Technology’ award at the prestigious British Construction Industry 2016 Awards.
