Testing of Crushed Stone and Gravel
Laboratory assessment of aggregate quality for bases, concrete, road construction and industrial construction.
About the service
Crushed stone and gravel are the principal aggregate materials used in bases, concrete mixes, drainage systems, road pavements and industrial construction.
The quality of aggregates determines the strength of concrete, the stability of the base, freedom from subsidence, pavement durability and the correct performance of the structure under load.
Deviations in composition, contamination with dust and clay particles, or non-compliance with strength or frost-resistance requirements reduce concrete quality, damage road layers and cause cracking and deformation.
Our laboratory carries out comprehensive testing of crushed stone and gravel in accordance with GOST and design requirements, determining their suitability for a specific type of works.
You receive an official test report accepted by technical supervision and regulatory authorities.
Methods and standards
The list is adjusted to the design and accreditation scope. If a method is missing, ask our engineer.
| Method | Standard | Where |
|---|---|---|
| Crushed stone: grading, crushing, flakiness | GOST 8269.0-97 | Laboratory |
Why it matters
Testing makes it possible to:
- 01confirm that the material meets GOST requirements
- 02rule out the use of low-quality aggregates
- 03prevent a loss of strength in concrete and road pavements
- 04monitor suppliers and batch quality
- 05detect excess dust, clay and organic impurities
- 06ensure base stability and the absence of subsidence
- 07provide documented confirmation of material quality on site
Using verified aggregate material is a mandatory condition for safe, durable construction.
Testing stages
- 01
Receiving the request and design requirements
We clarify the material type, area of application and the parameters to be assessed.
- 02
Sampling or receiving the material
We take samples on site or accept material delivered to the laboratory.
- 03
Preparing specimens
We dry, sieve, classify and prepare the samples for investigation.
- 04
Laboratory investigation
We determine the physical and mechanical properties needed to classify and assess the material.
- 05
Analysing the results and comparison with standards
We compare the indicators against GOST and design documentation requirements.
- 06
Issuing the official report
We provide a document with the test results and recommendations on using the material.
Our advantages
- Accredited testing of crushed stone and gravel to GOST
- Quality control of aggregates for concrete and road bases
- Modern equipment and precise methods
- Fast turnaround and on-site sampling available
- A complete documentation package for construction control
Who it is for
- Construction and road-building companies
- Concrete and precast concrete producers
- Developers and technical supervision
- Aggregate suppliers
Testing crushed stone and gravel is a key stage in quality control of aggregate materials before use in construction.
We provide accurate laboratory investigation and issue official reports confirming that the material meets the requirements.
