Testing of Sand-Gravel and Crushed Stone–Gravel–Sand Mixes
Laboratory quality control of sand-gravel mix (SGM) and crushed stone–gravel–sand mix (CGSM) for road construction, bases, bedding layers and engineering structures.
About the service
Sand-gravel mixes (SGM) and crushed stone–gravel–sand mixes (CGSM) are key materials for building bases, road structures, foundation bedding layers and backfill for engineering structures.
Their quality determines the strength of the base, freedom from subsidence, retention of pavement geometry and the durability of the entire structure.
Our laboratory carries out comprehensive testing of SGM and CGSM in accordance with current GOST standards, checking physical and mechanical properties, composition, uniformity and compliance with regulatory requirements. We determine the material's suitability for specific construction conditions and issue official reports for design and installation works.
Why it matters
Testing makes it possible to:
- 01confirm that the mix meets GOST and design documentation requirements
- 02rule out base subsidence and pavement deformation
- 03assess the quality and uniformity of the material
- 04detect non-compliance in particle size or dust/clay content
- 05verify that the mix will withstand the design loads
- 06provide documented confirmation of the quality of delivered volumes
Testing is mandatory when preparing bases for roads, slabs, industrial pavements and large construction projects.
Testing stages
- 01
Receiving the request and reviewing the project
We determine the requirements for the mix type and the scope of testing needed.
- 02
Sampling on site or receiving the material
Specialists sample the material in accordance with the standards, recording the conditions and locations of sampling.
- 03
Preparing the sample for investigation
We dry, cut, classify and prepare the material for laboratory procedures.
- 04
Carrying out the tests
We determine the physical and mechanical characteristics of the mix, its structure, composition and compliance with the standard values.
- 05
Analysing the results and comparison with requirements
We classify the mix precisely and assess its suitability for the specific type of works.
- 06
Issuing test reports
The client receives an official document with conclusions and recommendations on using the material.
