Learn more about product standards and specifications.
Standards and specifications play a critical role when developing, selecting and specifying the most appropriate products and materials for projects.
Standards are published documents that set out specifications and design procedures to ensure products and services consistently perform safely, reliably, and the way they're intended to.
There are Australian and international standards, standards developed by certain regulators, and industry standards developed by professional industry associations which relate to the performance of particular activities within the industries.
Standards are living documents which are updated to suit the changing needs of the economy and community. Standards are everywhere in your daily life, from the buildings you live in, to the way seatbelts operate in your car.
Specifications outline the requirements of a specific company or product. A specification provides specific requirements for the materials, components or services used in an application. Sometimes, a specification will also dictate the installation or design layout of those components. Specification requirements may go above and beyond what is required in the standard.
The Department of Transport (DoT) is a national leader in the use of recycled products in pavement construction. They take an equal opportunity approach to specification that is intended to allow contractors to choose between equivalent recycled or virgin quarry materials, based on price and availability.
Below are some DoT sections that include considerations for recycled content.
Regulation Gap Graded Asphalt
RAP (Reclaimed Asphalt Pavement)
Sprayed Bituminous Surfacings
RAP (Reclaimed Asphalt Pavement), tyres/rubber, aggregate, glass
Hot mix asphalt
High Binder Crumb Rubber Asphalt
Light Traffic Crumb Rubber Asphalt
RAP (Reclaimed Asphalt Pavement), tyres/rubber
Slag, fly ash
Underground Stormwater Drains
RAP (Reclaimed Asphalt Pavement), slag,aggregate, glass
General concrete paving
Glass, slag, fly ash
Noise attenuation walls
Recycled products with physical properties that comply
Materials Sources for the production of crushed rock and aggregates
RAP (Reclaimed Asphalt Pavement), crushed concrete, Electric Arc Furnace (EAF) slag, glass and brick (supplementary material only)
Crushed rock for pavement base and sub-base
Aggregate, glass, crushed brick, crushed concrete
Base and Subbase for Lower Trafficked Roads
Cementitious Treated Crushed Rock for Pavement Subbase
Technical note 107
Use of recycled materials in road pavements
RAP (Reclaimed Asphalt Pavement),tyres/rubber, aggregate, glass, crushed concrete, crushed brick
Please note: Some of these standards cross-reference each other creating opportunities to use recycled materials. For example, Section 705 (Drainage Pits) references Section 703 (General Concrete Paving) which allows the use of slag and unwashed glass.
