EN 12274-1:2018
(Main)Slurry surfacing - Test methods - Part 1: Sampling of slurry surfacing mixture
General Information
- Abstract
This European Standard applies to slurry surfacing for roads, airfields and other trafficked areas.
This European Standard specifies a method for sampling of slurry surfacing mixtures from production during laying.
A method for sampling from the road surface after laying is described in an informative annex (Annex A) for evaluation purposes.
Production testing needs operators with good practice and is carried out provided there are no specific local or other national regulations that are required to be followed.
WARNING - The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of the standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Overview
EN 12274-1:2018 - Slurry surfacing: Test methods - Part 1: Sampling of slurry surfacing mixture (CEN) defines how to take representative samples of slurry surfacing and microsurfacing mixtures for roads, airfields and other trafficked areas. The standard covers sampling from production during laying and gives an informative annex for sampling from the finished surface. It is intended to support consistent quality control and laboratory testing of slurry surfacing materials.
Key topics and technical requirements
- Scope: Applies to slurry surfacing for roads, airfields and other trafficked areas; sampling from production is mandatory for testing.
- Apparatus:
- Containers with a minimum capacity of 0.5 L (multiple containers allowed to achieve required sample volume); tightly fitting lids recommended.
- Stirring rod with diameter 20–30 mm and suitable length to obtain a homogeneous sample.
- Sampling procedure:
- Take samples during production immediately before laying, once the laid material appears uniform. Do not sample at the very start or end of a production run.
- Ensure the paving machine has laid at least 30 linear metres before sampling (exception: small machines for footways/cycleways may sample at any time or from a batch mix).
- Collect sample by holding container(s) in the full flow of the discharging mixture until full but not overflowing. A sampling frame is recommended for safety and convenience.
- Pack and store samples to avoid contamination or damage. If a sample must be large or subdivided, stir continuously until an initial set to prevent aggregate settlement and segregation.
- Labelling and reporting: Minimum information required includes producer, slurry type (e.g., base/surface layer, aggregate grading, modifiers), date, machine identification, sample designation, location/site, and any deviations from the standard. Optional fields: weather, emulsion origin, sampling time.
- Annex A (informative): Procedure for sampling after laying - use self-adhesive masking tape (minimum area 0.1 m² and minimum thickness 0.2 mm) positioned to obtain representative samples (road samples at least 30 m from start), remove after set and package to avoid contamination.
Note: The standard includes a safety warning - users must observe appropriate health and safety practices and applicable regulations when handling slurry surfacing materials.
Applications and users
- Quality control teams and contractors producing slurry surfacing or microsurfacing
- Materials laboratories performing compliance and performance tests
- Road authorities, specifiers and inspectors verifying in‑situ and production quality
- Project engineers seeking consistent sampling for durability, wearing-resistance and content testing
