Overview

prEN 1429:2026 is a draft European Standard published by CEN, addressing bitumens and bituminous binders. Specifically, this document details methods for the determination of residue on sieving of bituminous emulsions and the assessment of storage stability by sieving. Using established laboratory procedures, prEN 1429 provides a common reference for detecting the amount of coarse particles in bituminous emulsions and evaluating the stability of these emulsions over time.

Bituminous emulsions are widely used in road construction and maintenance, where product consistency and workability are crucial. Sieve residue and storage stability tests are essential for ensuring that these emulsions meet quality and performance requirements throughout their storage and application life cycle.

Warning: The standard involves the use of hazardous materials and specialized equipment. Users must follow appropriate health, safety, and environmental practices when applying these methods.

Key Topics

• Residue on Sieving:
  The standard outlines procedures for determining the quantity (mass fraction) of coarse particles, using sieves with defined mesh sizes, typically 0.500 mm and 0.160 mm.

• Storage Stability by Sieving:
  Provides methodology to assess the formation of coarse particles in bituminous emulsions after a set storage period, a key indicator of product stability and usability.

• Laboratory Conditions:
  Methods are specified to be conducted under controlled conditions, typically between 18 °C and 28 °C. Special attention is given to sample handling, washing, drying, and weighing.

• Test Apparatus and Reagents:
  Lists the necessary apparatus (such as precision balances, sieves conforming to ISO 3310-1, ventilated ovens, and desiccators) and reagents (specific solutions for anionic and cationic emulsions).

• Reporting and Precision:
  Defines requirements for recording results, repeatability, and reproducibility, including test reporting and precision data to ensure consistent results.

Applications

The procedures specified in prEN 1429:2026 are essential for:

• Quality Control in Bituminous Emulsions Production:
  Ensuring emulsions have the desired particle size distribution and stability, directly affecting their application in road surfaces, waterproofing, and sealing.

• Product Certification and Compliance:
  Facilitates comparison with technical specifications and regulatory requirements, supporting producers, suppliers, and regulatory agencies in ensuring product conformity.

• R&D and Product Development:
  Enables manufacturers to validate formulation changes and optimize emulsions for improved storage stability and performance.

• Routine Laboratory Testing:
  Laboratories and inspection bodies use these methods for periodic verification and batch approval, critical for public works and infrastructure projects.

• Failure Analysis:
  Identification of stability or particle size issues that can impact laydown, durability, and the appearance of pavement or coatings.

Related Standards

For comprehensive quality assessment and terminology alignment, prEN 1429:2026 references several related standards, including:

• EN 58: Bitumen and bituminous binders - Sampling bituminous binders
• EN 12594: Bitumens and bituminous binders - Preparation of test samples
• EN 12597: Bitumens and bituminous binders - Terminology

• ISO 3310-1: Test sieves - Technical requirements and testing - Sieves of metal wire cloth
• EN 12847: Determination of settling tendency of bituminous emulsions

These related standards support prEN 1429:2026 in delivering consistent test methodologies and terminology throughout the bitumen emulsion industry and laboratories.

3.1
residue on sieving
mass fraction in % of particles retained on a sieve of a mesh size specified in this document
3.2
storage stability
ability of a bituminous emulsion not to form more coarse particles within a period specified under an
appropriate emulsion specification
Note 1 to entry: Storage stability is a different concept than settling tendency as defined and measured by
EN 12847 [1]. Although both phenomena are often linked, an emulsion may settle without modification of particle
size distribution (no coalescence of emulsion droplets).
Note 2 to entry: The purpose of the limits fixed by the emulsion specification is to ensure that there cannot be
any disturbance of the workability of the bitumen emulsion under practical conditions.
3.3
normal laboratory conditions
a range of temperature between 18 °C and 28 °C
4 Principle
A known mass of bituminous emulsion is filtered either through a prepared sieve with a mesh size of
0,500 mm or through two prepared sieves with mesh sizes of 0,500 mm and of 0,160 mm. The amount of
binder retained on the sieves is weighed after washing and drying.
Storage stability is determined as the amount of binder retained on the sieve with a mesh size of
0,500 mm after a defined storage period (n days).

a
Aqueous phase solution of nominal 0,01 mol/l of sodium hydroxide (NaOH) containing a nominal 1 %
mass fraction of sodium oleate. This solution, or the actual aqueous phase, may be used for the

c
Aqueous phase solution of nominal 0,01 mol/l of hydrochloric acid (HCl) containing a nominal 1 % mass
