Quarry - Central Queensland Transmission Projects

⁠⁠⁠1. Crushed Rock and Aggregates Road Base:

- Crushed rock used for road and pavement sub-layers.

- Gravel: Varieties such as 5mm, 10mm, and 20mm aggregates used in concrete production and drainage.

- Crusher Dust: Fine aggregate used for compaction, bedding, and as a fill material.

- Mobile or fixed re-processing plant capable of crushing, screening, and blending excavated rock for reuse as road base or engineered fill.

- Material handling systems to enable reuse of cut rock from one part of the project as fill in other project areas.

2. Sand and Shale

- River Sand: Fine, natural sand used in concrete, mortar, and asphalt.

- Manufactured Sand (M-Sand): Crushed sand alternative, used in concrete mixes.

- Concrete Sand: Coarse sand used in ready-mix concrete production.

- Shale: Material for cement mix and fill.

3. Rubble and Riprap Riprap (Rock Armour):

- Large stones used for erosion control and stabilising of slopes.

- Gabion Stone: Medium-sized stones used in wire cages for retaining walls and embankments.

- On-site or regional mobile plant for processing oversize rock into graded aggregates suitable for drainage, road base, or engineered backfill.

4. Asphalt and Road Pavement Materials

- Asphalt Aggregates: Specific aggregate blends used in asphalt production for road surfaces.

- Road Pavement Material: Base materials like sub-base gravel and road base blends used for foundational road layers.

5. Ancillary Civil and Drainage Materials

- Supply of geotextiles and related geosynthetic products for soil stabilisation, separation, and drainage.

- Engineered subgrade materials to meet road and foundation performance specifications.

- Culverts and drainage solutions, including precast concrete or alternative systems compliant with relevant Australian Standards.
