Abstract

Civil Engineering Transportation and Freight Services
Proof rolling of granular layers in aircraft pavements is an integral part of the pavement thickness design methods used in Australia. The Department of Defence has a fleet of special purpose pneumatic tyred rollers with the capability to operate at up to 50 t on four wheels with tyre pressures of 1,400 kPa. In 2004 the tyre manufacturers reduced the maximum allowable tyre pressures to 1,000 kPa, creating a gap between aircraft load and the capacity of the proof rollers. To allow flexible aircraft pavements to continue to be constructed, one roller was upgraded to include solid urethane tyres with an effective contract pressure of 1,700 kPa and higher. Whilst this roller has undergone a preliminary trial that was found to be successful, further trials are required prior to upgrading the remaining roller fleet.
