GOST 52056 Bitumen Standards
Explore GOST 52056 standards defining bitumen classification, test codes, and quality control requirements across Russia and CIS countries.
Russia’s Standard for Bitumen Quality
GOST 52056 Bitumen Standards
The GOST 52056-2003 standard is the Russian interstate specification governing the classification, testing, and performance of Polymer-Bitumen Binders (PBB), internationally known as Polymer Modified Bitumen (PMB).
It ensures uniform quality and performance for road, bridge, and airfield construction throughout Russia, Eastern Europe, Central Asia, and CIS countries.
By incorporating polymers such as SBS (styrene-butadiene-styrene) into conventional bitumen, the standard delivers enhanced material properties, ensuring durability, flexibility, and resistance to temperature extremes.
Key Advantages of GOST 52056-2003 Polymer-Bitumen Binders
Compared to traditional paving-grade bitumen, binders produced under GOST 52056-2003 offer:
- Higher deformation resistance under heavy traffic and elevated temperatures
- Superior elasticity and flexibility in cold climates
- Improved aging and fatigue resistance, extending pavement life
- Reliable performance for demanding infrastructure projects
The standard defines several grades, including PBV 40, PBV 60, and PBV 90, classified according to penetration, ductility, and softening point.
Standard Codes for Bitumen Properties
| Property | GOST Code | Description |
| Penetration | GOST 11501 | Defines consistency and hardness |
| Softening Point | GOST 11506 | Determines temperature at softening |
| Ductility | GOST 11505 | Measures elasticity |
| Flash Point | GOST 4333 | Indicates ignition threshold |
| Solubility | GOST 11508 | Confirms composition and purity |
| Elastic Recovery | GOST 52289 | Evaluates polymer modification quality |
| Fraass Breaking Pt | GOST 11507 | Determines brittleness at low temp. |
These tests ensure consistent and verifiable material quality for polymer-modified binders.
Methods by Bitumen Type
- Paving Grade Bitumen: GOST 33133
- Modified Bitumen: GOST R 58400.1
- Viscosity Grade: GOST 52056-2003
These tests standardize product quality for infrastructure development and export reliability.
