KSUAE Master student developed a program for selecting the grade of bitumen according to the PG system
Danif Samatov, a Master student of the KSUAE Department of Digital Road Technologies, has developed a program for selecting a bitumen binder grade according to PG.The BitOptima program he developed automates the process of selecting the optimal bitumen binder grade according to the PG system based on calculations of adjusted temperatures of pavement layers. It takes into account climatic data, the thickness of material layers and loads, helping engineers quickly select the appropriate material. Thanks to this, errors are eliminated and calculation time is reduced.
PG (Performance Grade) is a classification system for road bitumens based on their performance characteristics at different temperatures. Unlike previously used standards that determine the bitumen grade by viscosity or penetration, the PG system takes into account real climatic conditions and loads to which the road surface is subjected. The PG classification includes two temperature indicators: high (for example, PG 76) and low (for example, -22), which indicates the range of temperatures in which the bitumen retains its properties. This approach allows the use of materials that are resistant to deformation at high temperatures and cracking at low temperatures.
PG bitumens are widely used in road construction, especially in the design of asphalt concrete pavements for highways, airfields and other objects with high loads. They allow to extend the service life of roads, reduce repair costs and adapt the pavement to specific climatic conditions of the region.
