This test method is used to measure the ability of a concrete with a maximum coarse aggregate size of 20 mm or less to retain its water under pressure. This test determines the amount of water de-filtered when concrete is subjected to a certain…

Austroads Technical Specification ATS 5315 sets out the requirements for the supply of Special Class Concrete used in: bridges with a design life of 100 years

Austroads Technical Specification ATS 5341 sets out the requirements for the repair of cracks in concrete, including supply and quality of materials, surface preparation, application, relevant testing and acceptance criteria. The technical…

Austroads Technical Specification ATS 5317 sets out the requirements for the coring of hardened concrete for the purpose of assessing the in-situ concrete properties, including compressive strength, volume of permeable voids and density. It does not…

The Code of Practice for the Management of Alkali Aggregate Reactivity template has been developed for the use of Austroads member agencies. The document outlines the management strategies, testing and approval process required to regulate alkali…

One of the most significant breakthrough developments in concrete technology at the end of the 20th century was that of ultra-high performance ‘ductile’ concrete (UHPdC) with compressive strength up to 200 MPa and remarkable improvements in…

Reinforced concrete made its way into road bridges at the start of the twentieth century after being invented by Joseph Monier in 1875. By 1950 reinforced concrete was dominant for small and medium spans and vying with steel for longer spans. Their…

The Sulfate-resisting concrete is traditionally specified by cement type and concrete mix proportions in terms of maximum water-cement ratio and/or minimum cement content.

A wide range of test methods has been used to measure the resistance of concrete to chloride penetration. Each method is purported to measure the property of concrete central to the chloride transport mechanism into concrete. They include water…

The standard Super-T bridge girders used in Australia were developed to provide optimum performance at a time when the maximum concrete grade covered by the bridge design code was 50 MPa. This paper examines the opportunities for improved…
