Abstract

The paper investigates the liquid polymer-bitumen binder in a pipe with a sudden expansion. At small values of the expansion parameter, the formation of a high-viscosity liquid zone occurs in the axial region, and the effective viscosity decreases at the periphery and nearwall zones. The destruction process of structural bonds, which intensively proceeds near the flow from the supply pipe, leads to a decrease in the effective viscosity. The formation of a corner area of reverse flows is accompanied by the increase in the effective viscosity.
