Investigation of the process of unloading bitumen from railway tanks
The article is devoted to the analysis of the existing practice of heating and unloading bitumen from railway tanks. The results of measurements of temperature fields on the surface of tanks and a steam jacket are presented. Based on the calculated parameters, it was determined that up to 80% of the heat is lost into the environment during heating of bitumen in railway tanks. Ways to reduce energy consumption when transshipment of bitumen from railway transport are proposed.

Нормирование энергопотребления складов битумов и битумных терминалов
Цехи хранения и нагрева битумов являются энергоемкими участками предприятий дорожного хозяйства. Многообразие технологий и оборудования делает сложной задачу классификации линий подготовки битумов по энергоэффективности и осложняет проведение энергетических обследований. Авторами предложена методика назначения класса энергетической эффективности технологических линий подготовки битумов на основе расчета индекса энергоэффективности.

Rationing of costs for heating road bitumen
Heating road bitumen is an energy-intensive procedure. Energy consumption is determined by a number of factors, including start and end temperatures, heating duration, losses to the environment, and many others. The variety of heating methods and technologies, the features of technological equipment are the reasons for a significant variation in energy consumption. The article is devoted to the development of a classification for the regulation of energy consumption of enterprises for storage and distribution of commercial bitumen, as well as asphalt concrete plants. Consumption rates have been determined for energy efficiency classes A-G for technologies for working with wheels and when using bitumen storages.
