CutBack Bitumen Disadvantage
Due to kerosene content of cutback bitumen, they suffer from essential problems in utilizations per the following:
– Consuming the kerosene as a valuable commodity
– Environmental contamination due to evaporation of the solvent into the air and penetration into the soil layers and underground watersheds.
– Risks of combustion and respiration of kerosene while operating.
Using #water instead of for kerosene in bitumen emulsion, not only avoid the problems of cutback bitumen, but also it causes an increase in the bitumen efficiency and adhesiveness; meanwhile this type of bitumen has a higher quality and may be applied in lower temperatures.
