PG 64-22 bitumen is a functional bitumen, this bitumen, which is graded based on its performance at different temperatures, is classified and used based on two factors: traffic and pavement temperature.
The performance grade of bitumen or PG is the latest standard of the world. This method is a relatively new method that classifies bitumen based on the temperature conditions of different regions. In this method, the mechanical properties of bitumen are examined from completely scientific methods. In this method, a temperature range is assigned to the bitumen, and the consumer can choose the appropriate bitumen according to his desired location. Today, for polymer modified bitumen and pure bitumen according to the standard, a performance grade or PG is defined according to temperature and environmental conditions. The wider range or range of PG of a compound means more desirable properties and higher resistance.
Applications of bitumen PG 22-64
Although today’s produced bitumens are of very high quality, but the conditions of their use are basically the same as in the past, including sealing, adhesiveness and preparation of protective coatings. Today, more than 250 different uses for bitumen are considered in agriculture, construction, industries, road construction and many others. In this section, we discuss the use of bitumen in different uses.
Most of the bitumen produced in Iran and the world, which is known as natural bitumen, is used in road construction.
PG 64-22 is especially used in temperate regions with very cold winters.
