Properties
Product properties
Manufacturer values are shown with the supporting test basis. Project acceptance remains subject to the nominated mix, site conditions and the relevant road authority specification.
| Property | Value | Basis / note |
|---|---|---|
| Product type | Water-activated cold-mix asphalt; 5 mm and 13 mm mixes | Manufacturer technical data, February 2026. |
| Bag weight | 20 kg | 60 bags per pallet; 1.2 t per pallet. |
| Pallet dimensions | 1,100 × 1,100 × 800 mm | 10 layers of 6 bags. Do not stack pallets. |
| Water per 20 kg bag | At least 1 L; 1.5 L typical; excess water acceptable | Technical data specifies a minimum of 1 L. The site calculator uses 2 L as a conservative allowance. |
| Compacted density | 2.3 g/cm³ (2,300 kg/m³) | Used for coverage estimates at 40–50 mm. |
| Coverage guide | 40 mm: 100 kg (5 bags) + 5 L/m²; 50 mm: 120 kg (6 bags) + 6 L/m² | Manufacturer Table 5. Allow additional material for uneven or deep repairs. |
| Nominal aggregate size | 5 mm or 13 mm | 5 mm for fine finishes and footways; 13 mm for road pavement. |
| Application thickness | 5 mm type: 20 mm or more; 13 mm type: 30 mm or more | Where thickness exceeds 50 mm, place and compact in layers. |
| Marshall stability | 5.0 kN average in SAMI testing | SAMI ML04337, 7 days ambient cure. Maeda target is 4.9 kN minimum. |
| Early stability | 5.4 kN at 1 hour | Maeda technical data, 13 mm mix, 1 hour at 20 °C. |
| Resilient modulus | 1,900 MPa | SAMI ML04336, AS 2891.13.1, 7 days ambient cure. |
| Wheel tracking | 1.5 mm rut after 24 h conditioning at 40 °C | Road Science assessment. Unconditioned result 2.2 mm. Maeda 7-day wheel-tracking result 5,730 passes/mm. |
| Air voids | 9.6% Marshall specimens; 7.3% modulus specimens | SAMI reports ML04337 and ML04336. Values relate to laboratory-compacted specimens. |
| Time to traffic | Straight-line traffic immediately after watering and compaction | Allow approximately 2 hours at intersections and where wheels turn on the patch. Hardens significantly within 1 hour. |
| Application temperature | Workable down to −15 °C; wet or dry conditions | Manufacturer presentation. Cure rates slow at lower temperatures. |
| Shelf life — unopened | 12 months from manufacture | Store dry, out of direct sunlight and protected from rain. |
| Shelf life — opened | Use promptly; seal the opening if any material remains | Moisture in the air will begin the curing reaction. |
| Stacking | Maximum 10 bags high; do not stack pallets | Excess weight can create pinholes in the packaging and affect workability. |
| Binder | Bio-based binder component; approximately 50% of the asphalt binder replaced | Manufacturer technical data and presentation. No petroleum-based distillate solvents. |
| Colour | Black | Cured appearance may vary with aggregate and site conditions. |
| Safety classification | Not classified as hazardous under the supplied SDS | June 2025 SDS. Contains a small amount of flammable liquid; follow PPE and storage guidance. |
Independent testing

Methods, reports and project approvals
These results describe the tested material. They do not replace a project specification or road authority approval.
- Marshall stability and flow: AS 2891.5 — SAMI report ML04337, issued 17 September 2026.
- Resilient modulus: AS 2891.13.1 — SAMI report ML04336, issued 17 September 2026.
- Wheel tracking: Maeda 60 °C test data and Road Science 40 °C assessment (1.5 mm conditioned, 2.2 mm unconditioned).
- Mix selection: confirm 5 mm or 13 mm, nominated thickness, surface preparation and compaction method against the project requirements.
- Acceptance: road authority requirements, TTM, WHS and environmental controls remain project-specific.

Environment
A water-activated, lower-solvent binder system.
Aqua Patch uses a bio-based binder component and is supplied without petroleum-based distillate solvents. The manufacturer states that approximately 50% of the asphalt binder is replaced with bio-based material and that the product has no hydrocarbon leaching or evaporation. These are manufacturer statements; refer to the SDS and current technical documents for the full basis.
- Water-activated chemical cure — no solvent evaporation to develop strength.
- Approximately 50% of the asphalt binder replaced with bio-based material (manufacturer).
- No hydrocarbon leaching or evaporation stated in the June 2025 SDS.
- Suitable for wet-weather and standing-water repairs, reducing deferred work.
