Abstract

Measurements of the change in the dimensions of consolidated specimens of a mixture of bitumen and mineral filler under tension have shown that in addition to undergoing viscous flow the material progressively increases in volume. Both the shear and the volume‐flow have a viscous (permanent) and elastic (recoverable) component. A viscous Poisson ratio (σ~r~) and a deformational Poisson ratio (σ~d~) have been calculated; for the particular asphalt σ~c~ had a value of 0·085, and σ~d~ was nearly constant at a value of 0·175. Details are given of the method of calculating the viscous and the elastic shear deformation, and the viscous and elastic volume deformation.
