What is this BS EN 12697-32 - Bituminous mixture specimen preparation about?
Bituminous mixtures are used for road construction, roofing, waterproofing, and other such applications. BS EN 12697-32 specifies methods for the preparation of bituminous test specimens using a vibratory compaction technique.
BS EN 12697-32 is applicable to loose mixtures and cores. BS EN 12697-32 is used to establish a refusal density for a bituminous mixture, or to determine the ease of compaction as described in EN 12697‑10.
Who is BS EN 12697-32 - Bituminous mixture specimen preparation for?
BS EN 12697-32 on bituminous mixture specimen preparation is useful for:
- Civil Engineers
- Road Contractors
- Highway Engineers
- Road Development Authorities
- Construction companies
- Roofing companies
Why should you use BS EN 12697-32-2019 - Bituminous mixture specimen preparation?
BS EN 12697-32 establishes a refusal density for bituminous mixtures that provide an indication of the potential maximum density which may be achieved under field conditions. BS EN 12697-32 provides mixing, preparation, and conditioning principles of bituminous materials in the laboratory.
BS EN 12697-32 helps determine the vibrating hammers’ suitability for laboratory compaction. Three types of test specimen preparation have been discussed – core specimens, plant-mixed materials, and laboratory-mixed materials. Using BS EN 12697-32 guidelines, you will be able to prepare test specimens of bituminous mixtures.
What’s changed since the last update?
BS EN 12697-32-2019 supersedes EN 12697-32:2003+A1:2007, which has been withdrawn. BS EN 12697-32-2019 contains some technical and editorial changes with respect to EN 12697-32:2003+A1:2007.
These include:
- The series title no longer makes the method exclusively for hot mix asphalt
- De-moulding of sample clarified
- Reference to apparatus for water content: EN 1097-5 replaces EN 12697-14
- [A.6] Deletion of brackets in formulae: [A.1] and [A.2]
