Austroads Technical Specification ATS 5320 sets out the requirements for the placement (including handling, compaction and finishing) and curing of special class concrete.
It applies to both cast-in-place and precast applications.
It does not apply to extruded concrete, sprayed concrete and cast-in-place concrete piles.
The technical specification can also be downloaded as a Word document.
Implementation of this technical specification relies on the availability of technical specifications which are in development:
- ATS 5326 Manufacture of Pretensioned Concrete Members
- ATS 5327 Post Tensioning of Concrete
- ATS 5321 Accelerated Curing of Concrete
This technical specification has been published to allow Austroads member agencies to prepare for implementation.
