STORAGE STABILITY OF CATIONIC BITUMEN EMULSIONS
The compositions of cationic road bitumen emulsions based on special emulsifiers ensuring high storage stability were developed. The variability of storage stability results obtained by different test methods was analyzed, namely: sieving after 7 and 30 days (using 0.14 mm and 0.5 mm sieves) and the settling tendency test on day 7. The study showed that the emulsifier content, emulsifier type, and acid type have a significant influence on storage stability. Emulsions with higher emulsifier dosages exhibited improved stability according to all applied methods.
