Railway Ballast Crushed Stone: GOST Requirements and Characteristics

Ballast crushed stone is the foundation of the railway. Train safety and the longevity of the entire infrastructure depend on its quality.

Why Is the Ballast Layer Needed?

Crushed stone in railway tracks performs several critical functions simultaneously.

It distributes pressure from sleepers to the ground, provides track elasticity, and effectively drains rainwater.

Main ballast functions:

• Load distribution from rolling stock
• Vibration dampening
• Water drainage from sleepers
• Preventing vegetation growth

GOST Requirements

In Kazakhstan, quality ballast crushed stone must strictly comply with state standards.

• Fraction: strictly 25-60 mm for the main layer.
• Strength grade: M1200 minimum.
• Abrasion: low (I1).
• Frost resistance: F100 minimum.
• Flakiness: no more than 18%.

Our quarry specializes in producing ballast crushed stone that undergoes daily laboratory quality control.

Quality Control

Each batch of crushed stone undergoes comprehensive testing in an accredited laboratory.

We issue conformity certificates and quality passports for all shipped material.

Conclusion

Ballast crushed stone is a critical material. Cutting costs on it is unacceptable.

Quality ballast ensures railway safety for decades.
