BS EN 1428 is a European standard on bitumen and bituminous binders.
The main objective of the BS EN 1428 is to ensure bitumen and bituminous binders play a positive role in maintaining the structural integrity of your civil engineering works.
It specifies a method for the determination of the water content in bituminous emulsions by means of distillation.
BS EN 1428 on the azeotropic distillation method for bituminous emulsions is useful for:
Bitumen emulsion is a mixture of fine droplets of bitumen and water and is also used for mixing and spraying in road construction and road maintenance. In this regard, the water content test in bituminous emulsions is to evaluate the bitumen emulsion quality. Water content present in the bitumen holds importance as excess water may result in foaming.
BS EN 1428 provides the criteria for apparatus, reagents, and materials, as well as the test sampling and technique for determining the water content of bituminous emulsions.
As a result, if you are a manufacturer of bituminous emulsions, complying with BS EN 1428 can demonstrate the performance and credibility of your product, assuring that it is fit for purpose.
The evaluation of the water content ultimately can assist you in improving design mixes such that they play a positive role in the setting and curing of bitumen emulsions.
