IMPORTANT INFORMATION
The assessment of quarried materials is paramount in the determining of suitability of these materials for use in any of the following: concrete, asphalt and sealing aggregate, rail ballast, road construction & civil earthworks. Our Quarried Materials testing services located at our Mawson Lakes laboratory caters for a wide range of specialised physical and mechanical testing equipment, including:
- Compression testing machine for determination of aggregate strengths as mention above (Aggregate Crushing Value & Wet/Dry Strength Variation)
- Los Angeles abrasion machine for determination of abrasion resistance of aggregates
- CBR Machine for the determination of California Bearing Ratio
In depth testing of soils and pavement materials is essential for the quality control of road construction materials, such as bases and sub-bases which are sometime commonly referred to crush rock and quarry rubble.Critical characteristics of any quarried material are consistency, durability and workability. |
