GOST 31015-2002 PDF

Full title and description

GOST 31015-2002 — Bituminous stone mastic mixtures and stone mastic asphalt. Specifications. Standard that establishes technical requirements, composition, production and acceptance rules for hot stone-mastic asphalt (SMA) mixes and SMA asphalt used as wearing (top) layers of pavements for roads, airfields, urban streets and squares.

Abstract

This standard specifies the composition, required properties, production and quality-control procedures for hot stone-mastic asphalt (SMA) and bituminous stone-mastic mixtures. It defines aggregate grading, binder types and contents, volumetric characteristics, production and laying temperatures, compaction requirements, sampling and testing methods, and acceptance criteria for SMA used in wearing courses of road and airfield pavements.

Scope

Applies to hot stone-mastic asphalt (SMA) mixtures and SMA asphalt intended for use as wearing (top) layers of flexible pavement structures for highways, airfields, urban streets and squares. The standard covers materials, mixture design requirements, production and laying procedures, testing methods for control and acceptance, and marking and documentation requirements for SMA batches and finished pavement layers.

Key topics and requirements

• Definitions and classification of stone-mastic asphalt (SMA) and bituminous stone-mastic mixtures for wearing courses.
• Requirements for aggregates: permitted rock types, grading limits, maximum particle size, cleanliness and resistance to polishing.
• Requirements for bituminous binders: types (including polymer-modified binders where specified), penetration/softening limits and compatibility with aggregates.
• Mixture design parameters: aggregate gradation, optimum binder content, filler type and content, volumetric parameters (air voids, voids filled with bitumen), and required mechanical properties.
• Production and handling: recommended mixing and laying temperatures, allowable moisture content, storage and transport of hot mix, and compaction procedures to achieve specified density and performance.
• Laboratory and field tests for control and acceptance: particle-size analysis, binder content determination, Marshall or gyratory stability/flow tests, bulk density, voids, moisture susceptibility, skid resistance and routine sampling procedures.
• Acceptance criteria, batch documentation and marking, and rules for corrective action when properties deviate from specified limits.

Typical use and users

Used by road and airport pavement engineers, highway authorities, pavement designers, construction and paving contractors, materials laboratories, material suppliers (aggregate and bitumen producers), and quality-control/inspection bodies responsible for specification compliance and acceptance testing of wearing-course asphalt mixes.
