Quarried Materials

The assessment of quarried materials is crucial to determine the suitability of these materials for use in concrete, asphalt, rail ballast, road construction and civil construction earthworks projects.

Lab and Field’s quarried material testing facility is fully equipped to provide detailed aggregate assessments, production testing, quality assurance and compliance testing of a wide range of quarried and recycled materials. These tests include the assessment of shape, size, density and hardness characteristics to ensure the consistency, durability and suitability of the material for the proposed end application.
