What is BS EN 13702- Bitumen and bituminous binders about?
BS EN 13702 is a European standard that discusses the binders of bitumen and bituminous. BS EN 13702 contains materials that are adhesive and waterproof which are obtained from the crude oil or present in natural asphalt.
BS EN 13702 specifies a method for determining the dynamic viscosity of a bituminous binder over a range of temperatures by means of a cone and plate viscometer. The test method is intended for all bituminous binders (e.g., paving grade bitumen and polymer modified), unaged or aged.
Who is BS EN 13702- Bitumen and bituminous binders for?
BS EN 13702 on bitumen and bituminous binders is useful for:
- Contractors
- Construction companies
- Civil engineers
- Manufacturers of bitumen and bituminous
Why should you use BS EN 13702- Bitumen and bituminous binders?
Bituminous binders are an adhesive material that contains bitumen, which may be in the form of conventional bitumen, modified bitumen, or bitumen emulsion.
BS EN 13702 provides you the cone factor for determining the viscosity of bitumen and bituminous binders which is applied for the individual equipment to obtain the actual viscosity from the readings which are mainly due to the geometry of the apparatus.
BS EN 13702 guides you with various types of specifications for bitumen and bituminous binders such as shear stress, shear rate, dynamic viscosity, Newtonian fluid, apparent viscosity, and cone factor, which helps you in determining the viscosity of bitumen and bituminous binders.
What’s changed since the last update?
BS EN 13702:2018 supersedes BS EN 13702:2010 (dual numbered as BS 2000‑513:2010), which is withdrawn. It includes:
- The Scope and title of the test method has been changed so the standard covers bituminous binders and not just modified bitumen
- The requirement in Clause 6 that the sample shall not contain any filler has been deleted. It is not the intention that the test method can be used on bituminous mortars but to accommodate the use of the test method for bituminous binders recovered from asphalt mixtures
- The test method has been changed to a general test method with the conditions at 60 °C, 100 °C and 150 °C given as examples
