Effectiveness of modification of bitumens used for hydroinsulating masses with imidazoline
Com. imidazoline was added (1% by mass) to a soft bitumen (softening temp. 40-42 degrees C) to modify its phys. properties before and after ageing at 163 degrees C for 75 min. The addn. of the imidazoline resulted in a significant increase in resistance of the bitumen to aging.
