Evaluation and Strengthening of Existing Bridges to Carry Increased Vehicle Weights
Detailed investigation and live-load evaluation was undertaken for several 1930s reinforced concrete bridges followed by strengthening where required.
A New Vehicle Loading Standard for Road Bridges in New Zealand
With the progressive increase in heavy vehicle loadings associated with improved transport vehicle technology, the current vehicle loading standard for the design of bridges in New Zealand, first introduced in 1972, may not be appropriate for use in…
Upgrading NZ Bridges for High Productivity Motor Vehicles
New Zealand (NZ) has introduced High Productivity Motor Vehicles (HPMV’s) to improve freight efficiency on its road network. The significant increase in vehicle mass limits has required a national bridge load capacity evaluation and strengthening…
Potential Framework for the Nationwide Assessment of Heavy Vehicle Access to Bridges
A key component to improving freight productivity in Australia is to improve access to the network for heavy vehicle operators. The assessment of bridge capacity is perceived to be critical to this aim. Currently a significant number of bridge…
Review of Axle Spacing Mass Schedules and Future Framework for Assessment of Heavy Vehicle Access Applications
A key component to improving freight productivity in Australia is to improve access to the network for heavy vehicle operators. Assessment of bridge capacity is perceived to be critical to this aim.
Development of Marginal Costs for Heavy Vehicle Bridge Usage
This report develops approaches that estimate the marginal cost (MC) of bridge wear for heavy vehicle usage and estimates the availability and reliability of the data needed to use these approaches. Two approaches were examined. The first was an…
Investigating the Development of a Bridge Assessment Tool for Determining Access for High Productivity Freight Vehicles
This report deals with the first component of the bridge assessment tool and is a scoping study to determine whether there is sufficient data, and whether there exists suitable engineering models, to develop robust and nationally uniform technical…
Auckland Harbour Bridge Box Girder Strengthening Design and Construction
The economic vitality of Auckland depends upon the movement of people and freight around the city’s motorways and the Auckland Harbour Bridge (AHB) is a crucial component of the network. Traffic loads derived from weigh-in-motion (WIM) data measured…
Network Assessment for High Risk Mobile Crane Under IAP
There are 5094 bridges and bridge size culverts under the jurisdiction of the Roads and Traffic Authority (RTA) NSW. More than 50% of these bridges were built before 1976 and design load was significantly lower than the T44 design load in accordance…
Guidelines for Assessing Heavy Vehicle Access to Local Roads
These guidelines are designed to assist Councils and operators when considering the access of restricted access vehicles to local roads. Although the regulatory environment varies across Australasia all heavy vehicles operate under three broad…
