is an interstate standard that specifies the technical requirements for crushed stone-gravel-sand mixtures used in the construction of road and airfield surfaces and bases. Although it was originally adopted in 1993, it is most commonly cited as GOST 25607-94 , which became effective on January 1, 1995. Status and Successors Sets limits on the effective specific activity of

It has largely been superseded by the more recent GOST 25607-2009 , which updated testing methods and technical requirements. However, the 1994 version is still frequently referenced in legacy project documentation and older technical specifications. Scope and Application

The standard defines several critical quality indicators for the mixtures:

Specifies the allowable range of particle sizes for various numbered mixture types (e.g., C4, C9).
