Instant Bitumen Cold Mix

By the Permanent Pothole Solutions team · Updated 26 October 2026

Pour enough to over-fill slightly, compact to a level finish and it’s ready to walk, drive or ride on.

What’s in Asphalt in a Bag

A ready-to-use pre-mix of selected aggregates, bitumen and a co-polymer. The polymer drives curing on compaction and makes the mix adhere to itself and to asphalt, concrete, steel and wood. A high fines content (sand and cone dust) fills voids, keeping air and water out — which is why you can use up to 20% less than other products.

Choosing the right gauge

Mix	Compacted lift	Best for
5 Gauge	12.5–20mm	Shallow repairs and fine finishes (made to order)
7 Gauge	17.5–28mm	Driveways, footpaths, shallow potholes
10 Gauge	25–40mm	All-purpose pothole and road repairs
14 Gauge	35–56mm	Deeper potholes and heavy-duty repairs

Why Asphalt in a Bag

Permanent. Expands and contracts with the road surface, so the patch moves with the pavement instead of breaking away.
Cures on impact. Curing is activated by compaction — tamp it or roll it and it sets.
Bonds to anything. Adheres to asphalt, concrete, steel and even wood.
Any weather. Apply from -26°C to 49°C, in rain, or straight into a pothole full of water.
No tack coat. No pre-coating or priming. Open, pour, compact.
Traffic-ready. Application is up to five times faster, and it can take traffic immediately.
