Bitumen BND 40/60 is a medium viscosity product with a viscosity index of 40–60 Penottek (Pn) at 60°C. This allows it to be used in more moderate climate zones, where the temperature ranges from -20°C to +30°C. Bitumen BND 40/60 has good fluidity during laying, which facilitates its use in asphalt concrete mixtures. This type of bitumen is stable at moderate temperatures and has good adhesion characteristics with aggregates and fillers, which makes it ideal for creating pavements that are not subject to early wear. Bitumen is used for laying road surfaces with medium loads, including secondary roads, as well as in moderate-temperate climates where high thermal resistance is not required. It is also used for the construction of asphalt concrete pavements for small and medium-sized highways, city highways and streets.
