Bitumen grade 50 has a melting point of around 50°C and is characterized by a higher viscosity compared to grade 40. This bitumen is more often used in regions with warmer climates, where the ambient temperature may be higher than in temperate zones. Bitumen grade 50 is also used in the production of asphalt concrete mixtures, which are required for road surfaces that are subject to more intensive loads, for example, in areas with high summer temperatures. It is also used in the construction of roads that must withstand high temperatures, since it has a higher resistance to heat.
