Bitumen Grade 85/100 60/70 80/100
Bitumen has several types and grade but 70% of usage is in road construction. Road construction has different step and using emulsion, cutback as basement and pavement and then penetration bitumen mixture with aggregates.Penetration bitumen: Bitumen 60/70 and bitumen 80/100 also 90/130 and 160/220 is soft grade of bitumen with high viscosity and categorizing by penetration. For instance bitumen 60/70 means penetration is between 60 to 70 and bitumen 80/100 is penetration bitumen with penetration between 80 to 100. Bitumen 60/70 and other grades is possible to ship it in bag and drum also bulk. Cutback and emulsion bitumen: Cutback bitumen is mixture of bitumen with solvent and depends on temperature and basement condition using slow curing, medium curing and rapid curing. Emulsion bitumen is mixture of bitumen with water including emulsifier additives to keep stable to mixture. The emulsion type is consisting of anionic emulsion and cationic grade slow setting, medium setting and rapid setting.
