Abstract
Thermal decomposition of the samples of cold-weather storage bitumen (heating with water vapour) was studied by means of thermogravimetric analysis. Bitumen was treated to remove water according to the regulations and with higher temperature and treatment time than those stated in the regulations. The effect of mechanically activated mineral additive and the additive imitating pyrobitumen on thermolysis was considered. Calculated activation energies of thermal decomposition of bitumen samples are reported.
