Research & reports
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 50â€“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.
