Product Overview

Summary: This SOP provides a clear, step-by-step method for the safe and effective application of cold mix asphalt on Australian worksites. It helps crews manage traffic, plant, and environmental risks while delivering consistent, long‑lasting repairs that stand up to local road conditions and WHS obligations.

Cold mix asphalt is widely used across Australia for pothole repairs, utility reinstatements, and small-area surfacing because it can be applied without heating, in variable weather, and with minimal traffic disruption. However, poorly controlled application can still expose workers and the public to significant risks, including live traffic, moving plant, manual handling injuries, slips and trips, and environmental contamination from bituminous products. This Safe Operating Procedure sets out a practical, field-ready method for planning, preparing, applying, and finishing cold mix asphalt works in a way that is both safe and compliant with Australian WHS expectations.

The document translates legislative and industry requirements into a repeatable process that front-line crews can actually follow. It covers everything from pre-start inspections, traffic management interface, and surface preparation through to compaction, quality checks, and site demobilisation. By adopting this SOP, organisations can reduce incident rates, lift workmanship quality, and demonstrate due diligence when audited by regulators or clients. It also supports consistent training for new and existing workers, ensuring that cold mix repairs are carried out the same safe way every time, regardless of location or crew composition.
