Heat loss effect on bitumen ageing in tanks

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.
