What is BS EN 12697-25 - Cyclic compression test for bituminous mixtures about?
BS EN 12697-25 specifies three test methods (A1, A2 and B) for determining the resistance of bituminous mixtures to permanent deformation by cyclic compression tests with confinement. BS EN 12697-25 make it possible to rank various mixtures or to check on the acceptability of a given mixture. BS EN 12697-25 describe methods for determining the creep characteristics of bituminous mixtures.
BS EN 12697-25 will help in the purpose of evaluation and development of new types of mixtures.
Note: BS EN 12697-25 applies to test specimens prepared in the laboratory or cored from the road. The maximum size of the aggregates is 32 mm.
Who is BS EN 12697-25 - Cyclic compression test for bituminous mixtures for?
BS EN 12697-25 on cyclic compression test for bituminous mixtures is useful for:
- Manufacturers and suppliers of bituminous mixtures and asphalt
- Suppliers of construction materials
- Construction and civil engineers
- Contractors
- Road maintenance authorities
Why should you use BS EN 12697-25 - Cyclic compression test for bituminous mixtures?
Bituminous materials are employed in a variety of applications, including road construction, roofing, waterproofing, and more. The principal application i.e., road construction, has the same major challenges as concrete in terms of cost and durability.
BS EN 12697-25 specifies test methods for determining the resistance of bituminous mixtures to permanent deformation by cyclic compression tests with confinement, which affect safety and comfort of road users. BS EN 12697-25 used for the purpose of evaluation and development of new types of mixtures. BS EN 12697-25 helps to ensure a durable pavement, sufficient strength to resist deformation under traffic at the higher temperature.
What is changed since the last update?
BS EN 12697-25:2016 supersedes BS EN 12697-25:2005 which is withdrawn.
BS EN 12697-25:2016 includes some technical changes with respect to BS EN 12697-25:2005. These include:
- Addition of uniaxial compression test with confinement for mastic asphalt
- Precision of friction-reducing system for loading surfaces
- Definition of loading signal for triaxial tests by identifying loading time and rest time, to be considered in EN 13108-20
- Implementation of digit numbers for test results
- Clarification of formulae and definitions
