What is BS EN 12274-3 - Determining the consistency of slurry surfacing mixtures about?
BS EN 12274-3 is the third part of the BS EN 12274 series of standards that discusses slurry surfacing. BS EN 12274-3 specifies a test method for determining the consistency of slurry surfacing mixtures. This test is dedicated to Slurry Seals (D ≤ 4mm).
Note1: BS EN 12274-3 can be used as a mixed design aid to determine the amount of water required to form a stable, workable mixture.
Note2: To obtain the correct consistency, BS EN 12274-3 can be necessary to repeat the test with different known percentages of water.
Note3: BS EN 12274-3 applies to slurry surfacing for roads, airfields, and other trafficked areas.
Who is BS EN 12274-3 - Determining the consistency of slurry surfacing mixtures for?
BS EN 12274-3 on the determining the consistency of slurry surfacing mixtures is useful for:
- Road and transport department
- Construction material manufacturers
- Civil engineers
- Construction companies
- Contractors
Why should you use BS EN 12274-3 - Determining the consistency of slurry surfacing mixtures?
Water forms an important part of a stable slurry and its percentage of the total mix is a major factor determining the consistency of the mix.
BS EN 12274-3 specifies a test method for determining the consistency of slurry surfacing mixtures that helps to check the right quantity of water to be added in the mixture.
BS EN 12274-3 will ensure that the slurry is not too dry that it cannot be mixed uniformly or too thin that will have inadequate viscosity to remain homogenous.
What’s changed since the last update?
BS EN 12274-3:2018 supersedes BS EN 12274‑3:2002, which is withdrawn.
BS EN 12274-3:2018 includes some technical changes with respect to BS EN 12274‑3:2002.
These include:
- The title is changed from “Slurry Seal” to “Slurry Surfacing” an editorial error
- The requirement for the slurry surfacing to be broken in 3.5 has been removed as this was a technical error
