  Bitumen performs the function of asubstance that binds particles of mineral material to form an asphalt concert coating . being  nonpolar , bitumen has high waterproofing properties . it is known that high-resinous and low-paraffinic petroleum is the most suitable for production of road and construction bitumen howere , due to the limited supply  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
