Bituminous mixtures - Test methods - Part 43: Resistance to fuel

This document specifies a test method to determine the resistance of a bituminous mixture or pavement to fuels. The procedure involves initial soaking of a test specimen made in the laboratory or cored from a pavement in a fuel, followed by a brushing period with a brush test device. The material loss of the specimen is a measure of the resistance to that fuel for that bituminous mixture.

Asphalt - Prüfverfahren - Teil 43: Widerstand gegen Treibstoffe

Dieses Dokument legt ein Prüfverfahren zur Bestimmung der Treibstoffbeständigkeit von Asphalt oder Fahrbahnbefestigungen aus Asphalt fest. Dieses Verfahren besteht darin, einen im Labor hergestellten oder durch Kernbohren aus einer Fahrbahnbefestigung entnommenen Probekörper zunächst in Treibstoff zu lagern und ihn dann in einem Bürstenprüfgerät zu bürsten. Der Materialverlust des Probekörpers ist ein Maß für die Beständigkeit des betreffenden Asphalts gegenüber dem betreffenden Treibstoff.

Mélanges bitumineux - Méthodes d'essais - Partie 43 : Résistance aux carburants

La présente Norme européenne spécifie une méthode d’essai destinée à déterminer la résistance aux carburants d’un mélange bitumineux ou d’une chaussée bitumineuse. Le mode opératoire implique tout d’abord l’immersion dans un carburant d’une éprouvette préparée en laboratoire ou extraite de la chaussée, suivie d’une phase de brossage au moyen d’un dispositif d'essai de brossage. La perte de matériau de l’éprouvette permet de mesurer la résistance du mélange bitumineux à ce carburant.

Bitumenske zmesi - Preskusne metode - 43. del: Odpornost proti gorivu

Ta dokument določa preskusno metodo za ugotavljanje odpornosti bitumenske zmesi ali voziščne konstrukcije proti gorivom. Postopek vključuje začetno namakanje preskušanca v gorivu, pri čemer je preskušanec izdelan v laboratoriju ali izvrtan iz voziščne konstrukcije, čemur sledi obdobje premazovanja s preskusno napravo za premazovanje. Izguba materiala preskušanca je merilo odpornosti proti posameznemu gorivu za določeno bitumensko zmes.

Overview

EN 12697-43:2023 - Bituminous mixtures: Test methods - Part 43: Resistance to fuel (CEN) specifies a laboratory method to assess how a bituminous mixture or in-situ pavement resists attack by fuels. The test combines a controlled chemical exposure (immersion in fuel) with a mechanical abrasion stage (brush test). The measured material loss after immersion and brushing is used to quantify fuel resistance of asphalt mixtures.

Key topics and technical requirements

• Test principle: Partial immersion of a cylindrical specimen in the specified fuel, cleaning and drying, followed by sequential brushing cycles using an epicyclical brush device. Total brushing time is 120 s (two 30 s cycles and one 60 s cycle). Material loss after immersion and after brushing are recorded.
• Specimen preparation:
  • Four cylindrical specimens are required.
  • Porous asphalt (voids ≥ 10 %): diameter (150 ± 2) mm, height (50 ± 5) mm.
  • Non‑porous asphalt (voids < 10 %): diameter (100 ± 2) mm, height (50 ± 5) mm.
  • Specimens may be laboratory-made (EN 12697-35, -30, -31) or cored from pavement (EN 12697-27).
• Apparatus & tolerances:
  • Beaker dimensions, glass rod to avoid air entrapment, and controlled fuel dosing to prevent specimen damage.
  • Balance with maximum permissible error 0.1 g; ventilated conditioning chamber at 25 ± 2 °C.
  • Two brush-test device options: adapted laboratory mixer or adapted milling machine; rotation speed (60 ± 3) min⁻¹.
  • Steel brush specification (cup brush, crimped steel wires, outer Ø 60 mm, trim length ≈ 17 mm) and replacement rules.
  • Soft-haired brush for cleaning and a pH‑meter for any required checks.
• Fuels: Use fuels at the concentration normally encountered in practice; safety precautions for high-concentration fuels and disposal of soiled water are emphasized.
• Results: Report combined and separate material losses (chemical and mechanical), visual inspection notes, specimen details and test conditions.

Applications and users

• Used by: materials laboratories, pavement engineers, road authorities, asphalt producers, contractors, and specification writers.
• Practical uses:
  • Compare fuel resistance of different asphalt mixes (porous vs non‑porous).
  • Support material selection where fuel spills or leaks are a risk (service stations, garage forecourts, heavy vehicle areas).
  • Provide evidence for pavement specifications, quality control and forensic investigation of surface damage after fuel exposure.

liquid (petroleum product) that might be spilled accidentally or sprayed deliberately onto an asphalt
pavement and can cause damage to the asphalt mixture
4 Principle
A cylindrical test specimen with a known mass is immersed partly in a bath with the specified fuel for a
specified period of time. After removal from the bath, cleaning with water and drying for 24 h at 25 °C,
the loss of mass of the specimen is measured and the immersed surface is visually inspected. Then an
abrasive loading is applied onto the immersed surface of the test specimen by a steel brush mounted
onto a brush test device. The steel brush moves in epicycloids passages over the surface. After 30 s the
brushing stops and the specimen is removed. The loss of mass is measured and the brushed surface is
visually inspected. The specimen is then put back and the same procedure is carried out again after 30 s
and after 60 s, when the brushed surface is visually inspected again.
The total brushing time is 120 s (two brushing periods of 30 s and one of 60 s). The combined material
loss after the immersion and the brush test is the main parameter for the resistance to the particular
fuel. As additional information the material loss after the immersion (chemical loading) and the brush
test (mechanical loading) are further informative parameters for the resistance to the particular fuel.
5 Apparatus
5.1 Beaker with glass rod
Cylindrical beaker made of glass for soaking the test specimen in the fuel. The container shall be flat-
bottomed and have an internal diameter of at least 140 mm (with porous asphalt specimens at least
190 mm) and an internal depth of at least 150 mm. A glass rod with a length of 70 mm and a diameter of
8 mm is put on one side of the bottom of the beaker so that one side of the immersed specimen can rest
on the bottom of the beaker and the other side on the glass rod to prevent the enclosure of air under the
immersed specimen.
5.2 Glass funnel
The size of the funnel shall be chosen in such a way that the rate of flow of the fluid into the beaker is as
small as possible to prevent any damage to the specimen because of the injection of the fluid in the
beaker.
5.3 Balance, with a maximum permissible error of 0,1 g.
5.4 Ventilated conditioning chamber, capable of maintaining temperature of (25 ± 2) °C in the
vicinity of the specimen.
5.5 Impact hammer, gyrator or roller compactor
Impact hammer (according to EN 12697-30), gyrator (according to EN 12697-31) or roller compactor
(according to EN 12697-33) to prepare laboratory made specimens.
5.6 Brush test device
Two different devices for the brush test are available.
5.6.1 Test device based on a laboratory mixer
Any mixer according to EN 12697-35 can be used. This mixer with epicyclical motion covers an area
with a diameter 5 mm less than the diameter of the specimen. The rotation speed shall be (60 ± 3)
−1
min .
The steel brush is connected to the mixer (see Figure 1).
