Q. How do you define cutback bitumen?

Answer

Oil products with reduced bitumen content are known as cutback bitumen (Kerosene). The goal is to make the bitumen more fluid so that it can penetrate deeper into the asphalt. Cutback bitumen, in contrast to traditional bitumen, is sprayed on roads at significantly lower temperatures. After being applied, the ingredients used to soften bitumen will evaporate, leaving behind a substance with the same hardness as the original bitumen. Primer seals can preserve pavement for up to 6-12 months when temperatures are too low for an efficient priming operation or when traffic is likely to disturb a primed surface before the final seal can be sprayed.
