Overview

EN 14998:2005 (CEN) establishes specifications and test methods for coal tar based fluxing oils used to reduce the viscosity of bituminous (carbonaceous) binders in road construction. The standard covers sampling, classification of grades, required analytical tests and an informative annex with handling and first-aid guidance for industrial use. It supports producers, laboratories, specifiers and contractors who work with coal tar fluxing oils and bituminous binders.

Key Topics

• Grades and purpose: The standard defines four grades (A, B, C, D) ranging from light to heavy fluxing oils. Each grade is intended for specific binder preparations:

  • Grade A: storable cold mix binders and slurry sealings
  • Grade B: binders for surface dressing (cold conditions)
  • Grade C: binders for surface dressing (warm conditions)
  • Grade D: oils from low-temperature distillation for precoated chippings

• Specifications and test methods: EN 14998:2005 prescribes analytical parameters and referenced methods, including:

  • Distillation characteristics (EN ISO 3405)
  • Density at 20 °C (ISO 3675)
  • Water content (ISO 760 or ISO 3733 alternative)
  • Crystallization temperature and benzo[a]pyrene content (EN 13991 and EN 1014-3)
  • Flash point (EN ISO 2719) and viscosity/efflux testing (EN 12846)

• Sampling: Samples for assessment are to be taken in accordance with EN 1014-1 to ensure representative laboratory testing.

• Safety and handling (Annex A): The informative annex highlights that coal tar fluxing oils are complex mixtures of polynuclear aromatic and heterocyclic hydrocarbons. It provides first-aid measures, safe handling, storage recommendations (keep containers sealed) and disposal guidance aligned with regulatory waste classification.

Applications

• Reduction of viscosity in bituminous binders for road construction and maintenance
• Preparation of storable cold-mix binders, slurry sealings, and binders for surface dressing
• Use in combination with petrochemical feedstocks where specified

Benefits for practitioners include better control of binder workability, compatibility across binder production processes, and harmonized test methods for quality assurance.
