Bituminous mixtures - Test methods - Part 13: Temperature measurement

This European Standard describes a test method for measuring the temperature of asphalt mixtures after mixing and during storage, transportation and laying. This European Standard includes the contact temperature-measuring device and the non-contact temperature-measuring device (infrared-thermometer).   In cases of dispute, the refence method shall be using the contact temperature measuring device.

Asphalt - Prüfverfahren - Teil 13: Temperaturmessung

Diese Europäische Norm legt ein Prüfverfahren zur Messung der Temperatur von Asphalt nach der Mischung und während Lagerung, Transport und Einbau fest. In dieser Europäischen Norm werden sowohl Kontakt-Temperaturmesseinrichtungen als auch berührungslose Temperaturmesseinrichtungen (Infrarot-Thermometer) erfasst.

Mélanges Bitumineux - Méthodes ďessai - Partie 13: Mesure de la température

La présente Norme européenne décrit une méthode d'essai permettant de mesurer la température des mélanges bitumineux après malaxage et pendant le stockage, le transport et la mise en oeuvre. Cette Norme européenne inclus l'utilisation de thermomètres de contact et de thermomètres sans contact (thermomètre infrarouge). En cas de litige, la méthode de référence doit être l'utilisation d'un thermomètre de contact.

Overview

EN 12697-13:2017 is a European Standard developed by CEN that specifies test methods for temperature measurement of bituminous (asphalt) mixtures. This standard covers temperature measurement procedures after asphalt mixing, during storage, transportation, and laying. It includes guidelines for both contact and non-contact temperature measurement devices, emphasizing accuracy and reliability. The contact temperature measuring device is the reference method in cases of disputes.

Accurate measurement of asphalt temperature is critical for quality control and ensuring the optimal performance of road construction materials during the paving process.

Key Topics

• Scope and Application
  The standard applies to temperature measurement of asphalt mixtures in various stages: immediately after mixing, during storage in heaps or lorry loads, and before or during laying and compaction.

• Measurement Principles

  • Contact Thermometer: Uses a probe inserted into the asphalt at specified depths and locations to get a representative temperature reading.
  • Infrared Thermometer: A non-contact device measuring surface temperature via thermal radiation, with emissivity adjustments for accuracy.

• Apparatus Requirements

  • Contact devices require probes with fast response times and accuracy within ±2 °C, long enough to measure deep inside heaps or lorry loads.
  • Infrared thermometers must operate within wavelength ranges 2 µm to 14 µm and allow emissivity setting between 0.90 and 0.98 depending on mixture type.

• Measurement Procedures

  • For contact thermometers:
    • Preheat probes to approximate material temperature before measuring.
    • Take multiple readings across different points at specified depths or surfaces.
  • For infrared thermometers:
    • Compare and calibrate with contact measurements to set correct emissivity.
    • Measure at an angle of 50° to 90°, ensuring the measured area fully covers the device's sensing field.
    • Take multiple measurements to calculate an average.

• Reporting and Documentation
  Test reports must include date, location, measurement method, equipment details, and averaged temperature results. Optional details may include project or supplier information.

Applications

• Quality Control in Road Construction
  Asphalt temperature influences compaction, endurance, and surface quality. Consistent monitoring via EN 12697-13 ensures materials meet performance requirements during paving.

• Material Handling and Transportation
  Measuring temperature in heaps and transport lorries prevents premature cooling, preserving mix workability and preventing material degradation.

• Safety and Compliance
  By following specified procedures, contractors comply with European regulations, ensuring safe and standardized measurement practices during roadworks.

• Process Optimization
  Temperature data helps optimize production and laying schedules, reduce downtime, and enhance overall project efficiency.

Related Standards

• EN 12697 Series
  EN 12697-13 is part of a broader suite of standards covering bituminous mixtures which include test methods for composition, mechanical properties, and performance. Other relevant parts include:

  • EN 12697-1 (Sampling)
  • EN 12697-8 (Determination of binder content)
  • EN 12697-24 (Wheel tracking test)

• CEN/TC 227 Road Materials
  This technical committee oversees standardization efforts on road construction materials, providing complementary standards that support EN 12697-13.

• ISO and National Standards
  Parallel standards for temperature measurement and asphalt testing exist in ISO and national bodies, which align with or reference EN 12697-13 for international harmonization.
