Alkali-Silica Reactivity of Aggregate - Concrete Prism Test
This Test Method determines the susceptibility of aggregate to an expansive reaction when mixed with cement in a concrete mix. It measures the change in length of concrete prisms containing the aggregate under investigation. This Test Method is not…
Alkali-Silica Reactivity of Aggregate – Accelerated Mortar Bar Test
This Test Method determines the susceptibility of aggregate to an expansive reaction when mixed with cement in a concrete mix. It measures the change in length of representative mortar bars containing the aggregate under investigation during storage…
Scoping Study for a National Heavy Vehicle Bridge Assessment System
Earlier Austroads investigations seeking to develop Bridge Formulae for inclusion in the Performance Based Standard Network Classification Guidelines concluded that there is little benefit to be gained from attempting to recompose the existing…
Webinar: Investigation and Development of Bridge Formulae for Inclusion in the Performance-based Standards
This webinar, presented on 29 April 2020, discusses the merits of three options to advance the future of PBS access in Australia as it relates to bridges. The webinar explains the role that PBS bridge formulae play in vehicle design and approval. It…
Investigation and Development of Bridge Formulae for Inclusion in the Performance-based Standards
The May 2018 National Transport Commission review of the Australian Performance-Based Standards (PBS) scheme revealed the need to improve the efficiency of heavy vehicle access via the PBS scheme to access substantial national freight productivity,…
Properties of General-purpose Cement with Increased Percentages of Limestone
This report presents the results of a research project commissioned by Austroads to investigate whether the currently used Australian general-purpose (GP) cement which complies with AS 3972, and which may contain up to 7.5% limestone as a mineral…
Bridge Assessment: A comparison of approaches by bridge engineers and the Performance Based Standards Scheme
This document describes the discrepancy between the tiers of bridge assessment documented in the Heavy Vehicle National Law&rsquo
Management of Heavy Vehicle Access to Bridges
Australia has regularly reviewed access to the road and bridge network with a view to increasing transport productivity. The current access regime for heavy vehicles has evolved over time with access now controlled by a range of regulations, notices,…
Strengthening of Bridges for Higher Productivity Freight Vehicles
Currently there is pressure from the freight industry to allow higher performance freight vehicles (HPFV) the use of major transport routes, particularly between the major centres of Brisbane, Melbourne and Sydney. An initial review of the existing…
Design and Constructability Challenges of Strengthening Existing Bridges
The exponential rise of the population and freight load in Victoria have led to a strong need for the upgrade of existing infrastructure to accommodate the increase in demand and loads of high productivity heavy vehicles. In many instances,…
