Bituminous mixtures - Test methods - Part 29: Determination of the dimensions of a bituminous specimen

This document specifies a test method for determining the dimensions of cylindrical, rectangular or non-rectangular bituminous test specimens by measurement.
The test is applicable to laboratory-made specimens, trimmed by sawing, or specimens from cores cut from the road, trimmed by sawing.

Asphalt - Prüfverfahren - Teil 29: Bestimmung der Maße von Asphalt-Probekörpern

Dieses Dokument legt ein Prüfverfahren fest, mit dem die Maße von zylindrischen, rechteckigen oder nichtrechteckigen Asphalt-Probekörpern durch Abmessen ermittelt werden.
Dieses Verfahren ist zur Anwendung auf im Labor hergestellte Probekörper bestimmt, die entweder durch Sägen zugeschnitten oder als Bohrkern aus einer eingebauten Fläche entnommen und dann durch Sägen zugeschnitten wurden.

Mélanges bitumineux - Méthodes d'essai - Partie 29 : Détermination des dimensions des éprouvettes bitumineuses

Ce document spécifie une méthode d’essai pour déterminer par mesurage les dimensions d’éprouvettes bitumineuses cylindriques, rectangulaires ou non-rectangulaires.
Cet essai est applicable à des éprouvettes préparées en laboratoire puis ajustées par sciage, ou extraites de la chaussée par carottage puis ajustées par sciage.

Overview

EN 12697-29:2020 - Bituminous mixtures: Test methods - Part 29 covers the standardized procedure for determining the dimensions of bituminous specimens used in asphalt testing. Published by CEN and approved in 2019 (superseding the 2002 edition), this test method applies to laboratory-made specimens and cores cut from pavements, both trimmed by sawing. The standard ensures repeatable, traceable dimensional measurements for cylindrical, rectangular and non‑rectangular bituminous specimens.

Key topics and requirements

• Scope: Measurement method for specimen dimensions (height, diameter, width, depth) of bituminous mixtures used in road construction materials.
• Apparatus: Minimum equipment includes a calliper gauge with accuracy of ±0.1 mm and an approved jig or holding device.
• General procedure: Specimens should be measured vertically (standing on upper face) or horizontally rolled on a level surface to access measurement points.
• Height measurement:
  • Take four measurements evenly spaced around the perimeter.
  • Each measurement made approximately 10 mm from the edge.
  • Average the four readings and report the height to the nearest 0.1 mm.
• Diameter measurement (cylindrical specimens):
  • For thickness > 60 mm: two perpendicular measurements at top, middle and bottom.
  • For > 30 mm to 60 mm: two perpendicular measurements at top and bottom.
  • For ≤ 30 mm: two perpendicular measurements in the middle.
  • Average the set of measurements and report to 0.1 mm.
• (Non-)rectangular specimens:
  • Take four measurements evenly spaced around the perimeter in each direction (height, width, depth).
  • If dimensions vary substantially (e.g., two‑point bending specimens), increase the number of measurements so specimen volume can always be calculated.
  • Measurements should be made near the edges and averaged to the nearest 0.1 mm.
• Reporting: Test report must state the measurement procedure used and list specimen dimensions to the nearest 0.1 mm.
• Precision: Note that the standard states the precision of this test has not yet been established.

Applications and users

EN 12697-29:2020 is essential for:

• Asphalt testing laboratories conducting volumetric and mechanical tests (e.g., density, voids, strength).
• Highway agencies, contractors and pavement quality assurance teams that require consistent specimen dimensions for comparative testing.
• Research institutions and material developers validating bituminous mix performance. Accurate specimen dimensions are critical for calculating volume, density and for ensuring reliable, comparable test results across projects.

Related standards

• EN 12697 series (other parts cover specimen preparation, conditioning and specific performance tests).
• General CEN/CENELEC road construction materials standards (EN family).
