What is BS EN 13074-1 - Recovery of binder from bituminous emulsion by evaporation about?
BS EN 13074 is a series of the European standard on bitumen and bituminous binders that focusses on the recovery property of binders which plays an important role in the performance and service life of building structures.
BS EN 13074-1 is the first part of the BS EN 13074 series of documents that specifies a method for the recovery of binder from a bituminous emulsion or from a cut-back or fluxed bitumen after conditioning at ambient temperature for 24 h followed by 24 h at 50 °C, in such a way that will enable further testing with minimum changes of the binder characteristics.
NOTE: BS EN 13074-1 covers all types of bituminous emulsions, modified with polymers or non-modified, as well as to all types of cut-back and fluxed bitumen, both modified with polymers and non-modified.
Who is BS EN 13074-1 - Recovery of binder from bituminous emulsion by evaporation for?
BS EN 13074-1 on recovery of binder by evaporation is useful for:
- Road constructors
- Builders
- Civil engineers
- Manufacturers of bituminous products
- Manufacturers of binders and sealing materials
Why should you use BS EN 13074-1 - Recovery of binder from bituminous emulsion by evaporation?
The recovered binder is the material remaining after the treatment of a bituminous emulsion or a cut-back or fluxed bitumen under the conditions specified.
BS EN 13074-1 provides the laboratory apparatus, sampling and test procedure to test the recovery of the binder.
BS EN 13074-1 navigates you through the determination of bituminous emulsion and cut-back or fluxed bitumen, their recovery procedure, removal and storage of the recovered binder and the preparation of the recovered binder sample for further testing.
BS EN 13074-1 gives the test method for cut-back and fluxed bituminous binders, which is to be followed by the stabilization procedure to get the recovery of the binder.
BS EN 13074-1 is helpful as it specifies test methods in evaluating the setting ability of fluxed bituminous binders made with vegetal fluxes.
Moreover, BS EN 13074-1 guides you in the extraction of binder in combination with a recovery method that is commonly used to evaluate the properties of a binder embedded in an existing building structure.
Bitumen and bituminous binders can thus be used in construction to examine the consistency, gradation, viscosity, temperature susceptibility, and safety of the building.
BS EN 13074-1 helps the user to protect the recovered blinder from excessive damage by providing a guideline regarding the procedures involved.
What’s changed since the last update?
BS EN 13074-1:2019 supersedes BS EN 13074-1:2011. BS EN 13074-1:2019 includes some technical changes with respect to BS EN 13074-1:2011. These include:
- More precise requirements for the ventilated oven and the metallic plates, as well as for the placing of the plates within the oven
- Description of additional equipment (beaker, oven) to be used for the reheating of the recovered binder samples
- Possibility is given for the determination of the water content of a bituminous emulsion
- Shorter storage period of the recovered binder samples before further testing
- More precise instructions (reheating temperatures and maximum reheating time) for the preparation of the recovered binder sample prior to further testing.
