Rehabilitation design of Victoria Road for barrier transfer vehicle

The quick-change moveable barrier (QMB) is a unique barrier system which allows a section of concrete barrier to be moved by a barrier transfer vehicle (BTV) into the carriageway at the start and end of each day (or more times if required) to provide a travelling lane with opposite directions at different times. Moveable concrete barriers have not been used in Australia previously. However, they are used extensively overseas, including in the U.S.A, New Zealand and the UK. In January 2011, for the first time in Australia, a moveable concrete barrier was introduced to Victoria Road, between the western abutments of the old and new Iron Cove bridges (east of Park Ave) and the Seymour Street intersection on Victoria Road. The BTV exceeds legal mass limits with its four wheels, each carrying about 10.5 tonnes when transferring the barrier. The Pavement Structures Section of the Engineering Technology Services (ETS Pavements) of Roads and Traffic Authority (RTA) analysed the original pavement in 2010 and so determined that the original pavement (JRCP with an asphalt overlay) would fail prematurely under the BTV loading. ETS Pavements subsequently carried out rehabilitation options that would avoid the demolition of the existing concrete pavement. Finite element analysis (FEA) was carried out to study the effect of the BTV loading on the existing JRCP. This paper describes the pavement investigation and design activities for this project and discusses the associated technical issues and challenges.
