General Information

Overview
EN 12697-31:2019 - "Bituminous mixtures - Test methods - Part 31: Specimen preparation by gyratory compactor" (CEN) specifies the procedure for compacting cylindrical specimens of bituminous mixtures using a gyratory compactor. The method applies to laboratory and site-sampled mixes with an upper aggregate size not larger than 31.5 mm. It is used to determine air-void content for given numbers of gyrations, to derive density/voids versus gyration curves, and to produce specimens of defined height or target density for subsequent mechanical testing.
Key topics and technical requirements
- Specimen preparation: Guidance on mass calculations and procedures for both dry and wet mixtures to achieve target specimen mass, height or density.
- Compaction parameters: Specification of controllable variables such as angle of inclination, axial stress, rotation speed and number of gyrations, and required temperature control during compaction.
- Apparatus and accessories: Requirements for the gyratory compactor, metallic moulds, round inserts, device for measuring insert distance, rotation counter, and auxiliary equipment (ventilated oven, balance, thermometer, and moisture collection provisions).
- Measurements and outputs: Determination of air voids content, specimen height after n gyrations, and derivation of a density (or void content) vs. gyration curve.
- Equipment compliance and calibration: Normative Annex A and Annex B describe procedures to demonstrate conformance of the compactor and to evaluate internal angle/related parameters (including a specified internal effective angle requirement noted in the standard).
- Precision and reporting: Clauses on test precision and the required information in the test report (e.g., mix type, number of gyrations, temperature, void content; water content may be reported where relevant).
- Normative references: Cross-references to other EN and ISO test methods used in density, voids and sample handling (e.g., EN 12697-5, -6, -8, -27, -35, -38, ISO texture and hardness standards).
Applications
- Mix design and compactability assessment: Evaluate how easily a mix achieves target density and estimate field compaction behavior.
- Laboratory specimen production: Produce reproducible specimens for rutting, stiffness, fatigue and other mechanical tests at specified density or height.
- Quality control and acceptance: Support QA/QC programs by linking laboratory compactability to on-site compaction processes.
- Research and development: Compare binders, aggregates and additives for their influence on compaction and void characteristics.
Who should use this standard
- Pavement/materials laboratories, highway agencies, mix designers, contractors, equipment manufacturers, and researchers involved in asphalt mix testing, quality assurance and performance evaluation.
Related standards
- EN 12697 series (other parts on density, voids, sampling, mixing), EN 12697-5, -6, -8, -27, -35, -38, and relevant ISO standards cited in the normative references.
