What is BS EN 13358 - Bitumen and bituminous binders about?
BS EN 13358 is a European standard that discusses bitumen and bituminous binders. Bitumen is a naturally occurring material and is found in large quantities in the solid or semi-solid forms of petroleum.
BS EN 13358 specifies a method for the determination of the distillation characteristics of cut-back and fluxed bituminous binders made with mineral fluxes.
Who is BS EN 13358 - Bitumen and bituminous binders for?
BS EN 13358 on bitumen and bituminous binders is applicable to:
- Heating engineers
- Manufacturer of bituminous binders
Why should you use BS EN 13358 - Bitumen and bituminous binders?
Bitumen in flexible pavements strongly binds and holds the other pavement components together and provides a smooth and levelled surface for the moving vehicles. Bitumen is a naturally occurring material and is found in large quantities in the solid or semi-solid forms of petroleum. Bituminous binders are adhesive materials that contain bitumen, which may be in the form of conventional bitumen, modified bitumen or bitumen emulsion.
BS EN 13358 navigates you through the procedure of distillation where the amount of the more volatile materials is measured in cut-back asphaltic products. BS EN 13358 also provides the mineral fluxes where the fluxes dissolve existing oxides on the metal surface and promote wetting with solder.
BS EN 13358 guides you on the principle of Petroleum cut-back and fluxed bituminous binders which are distilled at a controlled rate until the temperature of the liquid reaches 360 °C. This helps you measure the volume of distillate and residue obtained over specified temperature ranges.
With obedience and compliance to BS EN 13358, you can efficiently manufacture high-quality bituminous binders. In this manner, you can make sure that your products consistently meet and exceed quality expectations.
What’s changed since the last update?
BS EN 13358:2019 supersedes BS EN 13358:2010, which is withdrawn. It includes:
- Clause 5: an electric heating plate or heating mantle may be used as alternatives to the gas burner
- Clause 5: mercury stem thermometers are replaced by the temperature measuring devices allowing similar temperature determinations to be made. Annex A (characteristics of mercury stem thermometer) becomes informative
- Subclause 6.4.2: requirements on distillation rate (drops per minute) may be replaced by a minimum rate of temperature increase in cases where the distillation process has a very low yield
- Subclause 6.4.3: volumes of distillate are to be recorded at least at the reference corrected temperatures mentioned in EN 15322
- Clauses 6.4.3 and 10: the possibility to record volumes of distillate to a precision of 0,1 ml is abandoned
