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; and
- if specified the Contract documents, other structures such as retaining walls, culverts, deflection walls and safety barriers.
This technical specification can be downloaded as a Word document.
Implementation of this technical specification relies on the availability of technical specifications which are in development:
- ATS 5321 Temperature Matched Curing and the Maturity Method
- ATS 5328 Sprayed Concrete
- ATS 5335 Normal Class Concrete
- ATM 765 Determination of Calcium Nitrite Quantity in Fresh Concrete (Test Strips)
This technical specification has been published to allow Austroads member agencies to prepare for implementation.
