the article presents an overview of the most common ways of measuring the volume (mass) of bulk materials currently used in various industries. The comparative analysis presented in the article methods of assessment. It is established that current methods of calculating volumes of granular media have a number of disadvantages, which significantly affects the quality of the product and its value. It is revealed that it is most expedient to carry out measurement of the volume of granular media directly in the containers or the vehicle taking into account the main characteristics of the material — moisture content, bulk and true density, temperature and fractional composition.

The analysis of existing methods of warming up the "old" asphalt with regard to its further use. Found that known methods of heat grinding are energy-intensive, which limits their use in industry. A new method of thermal regeneration based inkjet influence of coolant with subsequent classification of the particles.
