Bitumen grade 40 has a melting point of about 40°C. It has low viscosity and is used in climate zones with moderate temperatures where strong temperature fluctuations are not expected. This bitumen is well suited for use in asphalt pavements on roads that are not exposed to extremely high temperatures. It is also used for waterproofing, as it has good water-repellent properties. Bitumen grade 40 is used in the production of medium-hard asphalt concrete, and it can be used for the construction of roads covered with an asphalt layer.
