Research report 400 Minimising traffic delays during resealing

Published: | Category: Integrated land use and transport systems , Research programme , Research & reports | Audience: General

This research demonstrated that:

  • racked-in seals can handle the stress of high-volume traffic
  • racked-in seals can be constructed in an eight-hour working period including any sweeping and road marking
  • closely controlled chip application rates result in minimal loose chip on surface
  • minimal loose chip results in minimal chip being flicked by vehicle tyres
  • speed restrictions can be lifted to 50–70km/h at the completion of the line marking
  • unrestricted traffic can be placed on the seal the morning after resealing.

The requirement for a newly sealed chipseal road to be opened to traffic speeds of at least 70km/h for peak evening traffic could be included in the construction specifications. This would assist in minimising motorists' frustration at the traffic delays caused by road sealing.
