Abstract:
The adhesive properties of brand BND 60/90 road bitumen with the oxidized phosphatide concentrate additive were studied. It was shown that the oxidized phosphatide increases the adhesive properties of bitumen brand BND 60/90. Oxidized phosphatide concentrate can be recommended as cost-effective alternative to expensive synthetic cationic surfactants, which are now widely used as adhesives for road bitumen. Based on the results of laboratory tests, the mathematical analysis of the obtained data was performed. Comparative graphs were plotted, and Pearson's correlation coefficients and the approx

Abstract:
The mandatory requirement for creating high-quality asphalt concrete is the modification of the bituminous binder. Either polymers, typically SBS, or crushed vulcanizates are usually used as modifiers. Using the polymer modifier has a number of disadvantages: the poor compatibility of polymers with bitumen, the stratification of the modified binder during transportation and storage, the coalescence of the dispersed phase particles at the coating laying temperatures. The use of crushed vulcanizate as a modifier is limited due to the complexity of obtaining a particle with a micro-size and compl

Abstract:
The article is devoted to laboratory research on the influence of convective motion as a result of thermal losses and their compensation in tanks on the physical and chemical ageing of bitumen BND 60/90 and BND 90/130. Laboratory tests of bitumen samples confirmed the hypothesis about the key role of free movement of bitumen in tanks on its degradation under conditions of maintaining operating temperatures and free air access. Thus, bitumen degradation has a functional relationship with thermal losses from the tank surface and the total energy input for bitumen heating.

Abstract:
The features of thermodynamic calculations for achieving the technologically necessary temperature of bitumen in the process of its heating with the help of a coil heater are considered. Based on the results of experimental studies, refined mathematical models were developed for calculating the main thermophysical properties (density, kinematic viscosity, isobaric heat capacity, coefficient of thermal conductivity and volume expansion) of bitumen grade BND 60/90 and hot coolant of thermal oil AMT-300, which used for heating bitumen. Analytical dependences are proposed, which make it possible t
