Overview - EN 12274-6:2018 (Slurry surfacing - Rate of application)

EN 12274-6:2018 is a CEN European Standard that defines test methods to determine the average rate of application of slurry surfacing in kilograms per square metre (kg/m2). It applies to slurry surfacing used on roads, airfields and other trafficked areas and is part of the EN 12274 series covering sampling, composition and performance tests for cold-laid bituminous surfacings.

Key topics and technical requirements

• Scope and units: Specifies measurement of the total mass of slurry surfacing applied per covered area (kg/m2).
• Two accepted measurement principles:
  • Constituent-record method (4.1): Sum masses of all mixture constituents from delivery tickets or continuous on-board recordings. Make allowances for residual stocks when appropriate. Convert any volume recordings to mass using constituent densities.
  • Weighing-machine method (4.2): Determine mass difference of the slurry machine before and after laying using fixed or portable weighing systems.
• Formulas:
  • Rate X = M / A (total mass M divided by covered area A)
  • Rate Y = M' / A (mass without processing water M' divided by A)
• Portable weighing system requirements:
  • Plates to weigh each axle, sized for double wheels
  • Minimum capacity: 15 000 kg
  • Slope (crossfall/gradient) during weighing < 3%
  • Accuracy (limit deviation): ±25 kg for axles ≤ 2 500 kg; ±50 kg for axles up to 15 000 kg
  • System must record mass per axle, date and time (printer optional)
• Test report contents: Mandatory items include reference to the standard, any deviations, date, location, procedure used (4.1 or 4.2), masses of constituents, covered area, calculated rate X or Y, and tester signature. Optional items include binder and water content and theoretical formulation.
• Precision: The standard notes that statistical repeatability and reproducibility information are not known.

Practical applications and users

• Who uses EN 12274-6:2018: highway authorities, airport pavement managers, contractors performing slurry surfacing, quality control laboratories, site inspectors and specification writers.
• Why it matters: Provides a standardized, traceable method to quantify material application rates for contract compliance, cost control, performance evaluation, and quality assurance of slurry surfacings on trafficked surfaces.
