Реологические характеристики нефтяных битумов по системе Superpave

Горение и плазмохимия
Increased traffic intensity and global warming require improvements in the requirements for the physico-mechanical characteristics of road construction materials. Standard physico-mechanical indicators of bitumen binders are insufficient for their recommendation in the composition of asphalt concrete mixtures, therefore it is necessary to determine ...
