Overview
The oSIST prEN 12697-14:2025:2025 standard, developed by CEN/TC 227, specifies a test method for determining the water content in bituminous mixtures. This test is critical for verifying the conformity of bituminous materials used in road construction to their product specifications. Accurate water content measurement helps ensure durability, performance, and safety of asphalt pavements.
This standard updates and supersedes the previous 2020 edition of EN 12697-14 and includes significant technical revisions to improve measurement accuracy and procedural clarity. It is aimed at laboratories, quality control personnel, and engineers involved in bituminous mixture testing.
Key Topics
Scope and Purpose
The method quantifies water present in bituminous mix samples, essential for product quality conformity assessment. It emphasizes safe handling and training for staff due to solvent usage risks.Test Methodology
The test uses a hot extractor method with specialized apparatus including a cylindrical container, reflux condenser, and balance precise to 0.1 g. The procedure involves heating samples to evaporate water, capturing it via solvents, and measuring the water volume.Solvents and Safety
Suitable solvents must dissolve bitumen and allow water recovery without decomposition, boiling below 85 °C to avoid water loss by evaporation. The standard warns about the hazardous nature of solvents like dichloromethane and requires adherence to occupational safety regulations.Sample Preparation
Samples must be prepared following EN 12697-27 to ensure representative portions. Portions are dried initially in an oven, and if mass loss exceeds 0.1%, the hot extractor technique is applied.Calculation and Reporting
Water content is calculated as a percentage by mass, rounded to the nearest 0.1%. Test reports must include sample identification, test results, deviations from procedure, and dates.Equipment Details
Figures illustrate the construction of the hot extractor components and pots, emphasizing corrosion-resistant materials and airtight solvent containment to ensure test reliability.
Applications
Quality Control in Road Construction
Ensures bituminous mixtures comply with moisture content standards, impacting asphalt’s binding properties and long-term pavement performance.Product Specification Verification
Confirms that mixtures meet vendor or regulatory moisture thresholds before use or delivery.Research and Development
Provides a standardized test to compare water content effects on new bituminous formulations or additives.Environmental and Safety Compliance
Supports safe solvent management practices in labs and field testing environments per current occupational health standards.
