Quarry Product Evaluation & Testing


BRG can provide complete testing and the independent certification required by the S.R.21 - Annex E requirements related to assessing the suitability of hardcore infill as per the S.R.21:2004 (Guidance on

the use of I.S. EN 13242:2002 – Aggregates for unbound and hydraulically bound materials for use in civil engineering work and road construction.)


Our geologists utilise a two phase approach to evaluating the Annex E S.R.21 requirements that keeps

costs to a minimum.



Phase 1 includes:


Grading and size analysis

Assessment of fines content and quality

Particles crushed, rounded or broken

Resistance to fragmentation

Magnesium sulphate soundness

Water absorption

Acid soluble sulphate

Total sulphur content


The results from the Phase 1 analysis

determine if a Phase 2 evaluation is necessary.



    Phase 2 includes:


     Petrographic examinations of samples

     using thin sections and X-ray diffraction




BRG can also provide assessment of the source aggregate products through their range of Geological assessment, Geophysical surveying, and Geochemical analysis.
