Formatted abstract
An investigation into the pavements of Terminals 1, 2 & 3, Fisherman Islands was undertaken to provide the Port of Brisbane Corporation (POBC) with a database of information regarding design and performance of a variety of pavements. The 14 week investigation concentrated on the previous reports by independent companies/authorities regarding design and maintenance issues of the industrial grade pavements founded on reclaimed land. Previous test results have been sourced in an attempt to discover any direct correlations between pavement performance and both pavement design and subgrade conditions.

Terminals 1 & 2 were constructed in two stages and operated for most of their life under loading different to that originally designed for. The change in operations caused local premature failure after only 8 years of a 25 year life, despite recommendations that the pavements would have sufficient strength. Failure occurred in both asphalt and concrete block pavements throughout Terminals 1 & 2.

Research has shown that the original pavement constructed at Terminal 3 was a 50mm asphalt surface covering 530]630mm of base materials. Transtainer strips of greater stiffness were incorporated into the design for the main traffic runways. The incorrect use of the pavements caused premature failure after only 7 years of service. It has been shown that straddle carrier operations may have exceeded the equivalent repetitions of the design forklift within the first 7 years of operation. Differing stiffnessfs of pavements was found to contribute to the unexpected rutting in areas where the transtainer strips were regularly crossed.

The combination of limited available resources and the observed pavement performance makes it impossible to suggest a preferred pavement. The major obstacle the Port of Brisbane Corporation face (common to all ports) is the unknown variation in terminal operations for the typical 25 year design life. Further studies are required into the whole life cost of alternative pavements verses those previously used at the Port of Brisbane. Future designs will need to incorporate the potential costs of additional maintenance caused by greater loading than that specified in the original design process.
