Polyfunctional Modifiers for Bitumen and Bituminous Materials with High Performance
Asphalt concrete (AC) coatings include two main components: bitumen and aggregates (crushed stone). Bitumen performs the function of a substance that binds particles of mineral material to form an asphalt concrete coating. Being nonpolar, bitumen has high waterproofing properties. It is known that high-resinous and low-paraffinic petroleum is the most suitable for the production of road and construction bitumen. However, due to the limited supply of this type of petroleum almost any oil residues are used. As a result, the quality of bitumen is very unsure at the moment and that leads to poor quality of bituminous materials resulting in poor quality asphalt concrete pavements.
