Bituminous mixtures - Test methods - Part 17: Particle loss of porous asphalt specimen

This European Standard specifies a test method for determining the particle loss of porous asphalt mixtures. Particle loss is assessed by the loss of mass of porous asphalt samples after turns in the Los Angeles machine. This test enables the estimation of the abrasion resistance of porous asphalt. The test applies to laboratory compacted cylindrical specimens of porous asphalt mixtures, the upper sieve size of which does not exceed 22,4 mm. It does not reflect the abrasive effect by studded tyres.

Asphalt - Prüfverfahren - Teil 17: Kornverlust von Probekörpern aus offenporigem Asphalt

Diese Europäische Norm legt ein Prüfverfahren zur Bestimmung des Kornverlusts von offenporigem Asphalt fest. Der Kornverlust wird anhand des Massenverlusts von offenporigen Asphaltproben nach Beanspruchung im Los-Angeles-Prüfgerät beurteilt. Diese Prüfung ermöglicht die Abschätzung des Abriebwiderstandes von offenporigem Asphalt. Die Prüfung gilt für im Labor verdichteten zylindrischen Probekörpern aus offenporigem Asphalt mit einer maximalen Korngröße von 22,4 mm. Sie spiegelt nicht die Abriebwirkung durch Spikereifen wider.

Mélanges bitumineux - Méthodes d’essai - Partie 17 : Perte de matériau des éprouvettes d’enrobé drainant

La présente Norme européenne spécifie une méthode d'essai pour déterminer la perte de matériau (abrasion) des mélanges d'enrobé drainant. L'abrasion est évaluée par la perte de masse d'échantillons d'enrobé drainant à l'issue de passages dans la machine Los Angeles. Cet essai permet d'estimer le comportement à l'abrasion de l'enrobé drainant. L'essai s'applique à des mélanges d'enrobé drainant confectionnés en laboratoire, dont la dimension granulaire maximale ne dépasse pas 25 mm. Elle ne reflète pas l'abrasion due à des pneumatiques cloutés.

Bitumenske zmesi - Preskusne metode - 17. del: Obraba delcev poroznih asfaltnih preskušancev

Ta evropski standard opisuje preskusno metodo za ugotavljanje obrabe delcev poroznih asfaltnih mešanic. Obraba delcev se oceni na podlagi izgube mase poroznih asfaltnih vzorcev po obračanju v stroju Los Angeles. Ta preskus omogoča oceno abrazivnosti poroznega asfalta. Preskus se uporablja za laboratorijsko utrjene porozne asfaltne mešanice, katerih največja velikost zrn ne presega 25 mm. Ne odraža učinka obrabe z ježevkami.

Overview

EN 12697-17:2017 - Bituminous mixtures: Test methods - Part 17 specifies a laboratory test method to determine the particle loss of porous asphalt specimens. Particle loss is measured as the mass loss of compacted porous asphalt cylinders after being tumbled in a Los Angeles machine. The method estimates the abrasion resistance of porous asphalt mixes (upper aggregate size ≤ 22.4 mm) and is intended for laboratory evaluation, not for representing the abrasive effect of studded tyres.

Key topics and requirements

• Specimens: At least five laboratory-compacted cylindrical specimens; mass (1.0 ± 0.2) kg (or 100 × 63.5 mm for typical bulk densities ≈ 2.0 Mg/m3).
• Manufacture & conditioning: Mixing per EN 12697‑35; compaction by EN 12697‑30 (2 × 50 blows) or EN 12697‑31 (40 gyrations). Store specimens on a flat surface between 48 h and 42 days at ≤ 25 °C before testing.
• Apparatus: Los Angeles machine (EN 1097‑2), accurate thermometer, temperature-controlled chamber (±2 °C), oven (±1 °C), and balances (accuracy ±0.1 % or 0.1 g).
• Test procedure:
  • Precondition specimens at test temperature for ≥ 4 h.
  • Place specimen in LA drum with metal balls removed; rotate 300 turns at 30–33 rpm (3.1–3.5 rad/s).
  • Remove loose particles, weigh specimen before (W1) and after (W2).
  • Calculate particle loss: PL = ((W1 − W2) / W1) × 100 and report the average of five values (rounded to the nearest 1%).
• Test temperature: Influences results strongly. Commonly 15–25 °C for design; not suitable above 35 °C.
• Precision:
  • For PL < 40%: repeatability r = 2%, reproducibility R = 4%.
  • For PL ≥ 40%: r = 5%, R = 8%.
• Limitations: Does not simulate studded-tyre abrasion.

Applications and users

Practical uses of EN 12697-17:2017:

• Assess abrasion resistance when designing or specifying porous asphalt mixes for drainage and noise-reducing surfaces.
• Compare mix variations (aggregate type, binder selection, gradation) for durability against particle loss.
• Support quality control and type approval in laboratories and material testing facilities.

Typical users:

• Pavement materials engineers and mix designers
• Road authorities and spec writers
• Construction contractors and quality-control laboratories
• Research organizations evaluating porous asphalt performance
