BS EN 12697-32:2019

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BS EN 12697-32-2019 supersedes EN 12697-32:2003+A1:2007, which has been withdrawn.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]
