What does "VicRoads spec" actually mean?

Everyone references it, almost nobody reads it. Here is what "to VicRoads spec" really means when it lands on your drawing.

Plain-English guideVictorian specs & unitsUpdated June 2026
Quick answer

"VicRoads spec" means the material is produced and supplied to a VicRoads standard section, the published documents that set grading, strength and source rules for road materials. For crushed rock that is mainly Section 812.

It also implies the rock comes from a registered source (an approved quarry) with test certificates to prove conformance. On a project that cannot fail, that paperwork is the point.

What a "section" is

VicRoads publishes standard specifications as numbered sections. Each one governs a material or activity, sets out exactly what conforms, and is referenced by number on drawings and in contracts. When a note says "crushed rock to VicRoads Section 812", it is pointing at that document.

Sections you will see most
SectionCovers
812Crushed rock for pavement base and sub-base (the classes)
815Cement treated crushed rock
204Earthworks
720Topsoil for road reserves and batters
RC 500.02A registration and source-rock code referenced for materials

The exact section numbers and titles are updated over time. Always work to the version called up in your project documents.

What "registered source" means

VicRoads work generally requires materials from a registered or approved source: a quarry whose rock has been tested and accepted as suitable for the specified use. It is not enough for the rock to look right; the source has to be on the list and the batch has to be certified.

This is why "some crushed rock" and "Class 2 to 812 from a registered source" are different orders. The second comes with a paper trail the superintendent can sign off. Buy the spec material as spec material, with the certificate.

Why it matters on real projects

01It is contractual. If the spec calls up a section, non-conforming material can be rejected and ripped out at your cost.
02It is about performance. The grading and strength limits exist so the pavement lasts its design life under traffic.
03It is about proof. Test certificates and source registration are what let the inspector accept the layer and you get paid.
04It removes argument. A number on a drawing and a certificate on the docket leave nothing to interpret.

How to handle it as a buyer

You do not need to memorise the sections. You need to read the class and section off the drawing, order to it, and ask your supplier for the conformance certificate. If the note is unclear, get it clarified before you order, not after it is in the ground. Send the drawing note to us with your quote request and we will confirm exactly what to supply.
