The penetration grade 85/ 100 is produced of distillation of crude oil in distilled tower . It is a semi hard bitumen with a strong viscosity in which considered as asphalf grade and generally used as paving application and construction works. penetration grade bitumen 85/100 could reach a softening point in 45/52C with the highest penetration ,85 to 100 desi-millimeter . This grade is a thermoplastic property that have a reaction alike synthetic resin which gets softer with heating and hardens when cooled. Because of its low, strong viscosity its a convenient product for hot weather conditions .
Bitumen penetration grade 85/100
The penetration grade 85/ 100 is produced of distillation of crude oil in distilled tower . It is a semi hard bitumen with a strong viscosity in which considered as asphalf grade to producing hot mix asphalt and generally used as paving application and construction works.
