What Is Aggregate Testing?
Aggregate testing involves assessing the physical and mechanical properties of materials to confirm they meet project specifications and are suitable for their intended application. Correct testing helps ensure the right material is used in the right application.
Why Aggregate Testing Matters
- Verify compliance with specifications
- Assess durability under loading and environmental conditions
- Confirm suitability for structural, pavement and rail applications
- Support quality assurance and material approval
- Reduce the risk of premature failure or rejection on site
Applications
- Concrete and asphalt materials approval
- Pavement and highway projects
- Rail ballast assessment
- Earthworks and drainage materials
- Infrastructure and development projects
