Austroads has published eight additional technical specifications and one associated test method which detail the requirements and guidelines for the use of concrete in the construction of roads and bridges
The release includes:
- ATS 5305 Formwork for Concrete
- ATS 5315 Special Class Concrete
- ATS 5316 Cementitious Mortar and Grout
- ATS 5317 Coring of Hardened Concrete
- ATS 5320 Placement of Concrete
- ATS 5325 Precast Concrete Members
- ATS 5341 Repair of Concrete Cracks
- ATS 5830 Incrementally Launched Prestressed Concrete Girders
- ATS 5860 Bonded Anchors
- ATM 780 Water Retention of Concrete – Filtration
These new technical specifications set out the requirements for the design, erection and removal of formwork, the supply and mixing of cementitious mortars and grouts, the coring of hardened concrete, the installation of post installed chemical anchors and the construction of prestressed concrete superstructures by incremental launching.
They also feature guidelines for the placement of concrete, including handling, compaction, finishing and curing of special class concrete, precast concrete members and for the repair of cracks in concrete.
Additionally, the new test method provides directions for measuring the water retention of concrete through filtration.
Austroads Project Manager of Transport Infrastructure, Ross Guppy, said, “As we continue to standardise construction requirements across Australia and New Zealand with this series of technical specifications and test methods, we work to harmonise contemporary construction practice and relevant Australian and New Zealand standards across jurisdictions.
“Austroads technical specifications and test methods are produced in consultation with industry and jurisdictions. They represent the value and benefits associated with knowledge sharing and consistency across borders.”
