What is BS EN 12697-20 about?  
BS EN 12697- 20 is the 20th part in the multi-series of European standard that discusses bituminous mixtures.
BS EN 12697-20 specifies a test method for determining the depth of indentation of mastic asphalt and other asphalt when force is applied to them via a cylindrical indentor pin with a circular flat-ended base.
Note: BS EN 12697-20 applies to aggregates of maximum nominal size less than or equal to 16 mm.
Who is BS EN 12697-20 for? 
BS EN 12697-20 on indentation using cube or marshall specimens is relevant to: 
- Manufacturers and suppliers of bituminous mixtures
- Suppliers of construction materials
- Construction and civil engineers
- Contractors
- Road maintenance authorities
- Testing laboratories
Why should you use BS EN 12697-20?  
Bitumen when used as a binder in asphalt, is widely used in the construction domain for road construction, paving and roofing. For bituminous concrete with a bitumen content of 5% by weight of the whole mix, a Marshall specimen is prepared.
BS EN 12697-20 specifies a test technique for evaluating the depth of indentation of mastic asphalt and other asphalt when force is applied using a cylindrical indentor pin with a circular flat-ended base. It gives you an indicator of the mixture's compressive resistance and also reveals the mixture's flow capacity, which varies based on the number of specimens used and the curing circumstances. This is beneficial in the construction of roads and buildings, as well as the waterproofing of asphalt surfaces.
BS EN 12697-20 can thus determine the load and flow rate of asphalt samples, ensuring high quality and performance of the end-use application. Accordingly, you can select the right construction materials for your engineering needs.
