Bitumen and Bituminous Binders - Determination of Efflux Time by the Efflux Viscometer - Part 2: Cut-back and Fluxed Bituminous Binders
Also Known As:
The DIN EN 12846-2 standard specifies a method for determining the efflux time of cut-back and fluxed bituminous binders. This is achieved using an efflux viscometer. The efflux time refers to the time taken for the bituminous binder to flow through a specified orifice under gravity at a constant temperature.
The standard is applicable to both cut-back and fluxed bituminous binders. Cut-back bituminous binders consist of bitumen diluted with a solvent, while fluxed bituminous binders are heated and mixed with fluxing agents to reduce viscosity. The efflux time measured using the efflux viscometer provides an indication of the flow characteristics of these types of bituminous binders. This information is important for various applications in the construction industry, such as road surfacing and waterproofing.
The DIN EN 12846-2 standard provides specific requirements and test conditions for conducting the efflux time determination. These include the temperature at which the test is performed, the dimensions of the orifice, and the method of sample preparation.
