Aggregates Testing
If you need to assess aggregates, stone or crushed concrete for use as capping, sub base, Type 1 or working platform material then we can help. We undertake a broad range of classification tests to asses whether material complies to a variety of specifications inducing, the 6F classes, MOT sub bases and aggregates used for other purposes such as in concrete.
Take a look below at the types of tests we offer from our central laboratory and on your site to help with aggregates assessment
On-Site Aggregate Testing
LWD Testing
Lightweight Deflectometer Test for roads, pile mats, crane bases
DCP Testing
Dynamic Cone Penetrometer Testing to obtain CBR for roads and geotechnical
Sampling
Obtain a representative sample for testing in the lab
Density & Compaction Testing
Laboratory CBR Testing
For determination of CBR values on remoulded material
Insitu Density using Sand Cone
Density tests on site for all aggregate types
Target Density
Lab Target density to compare in-situ density to
MCV Testing
MCV testing to assess moisture state of aggregate
Swelling Testing
Measurement of swelling under lab conditions for CBR specimens
Classification Testing
Particle Size by Sieveing
