ON THE MOVEMENT OF ASPHALT IN RESPECT OF PROBLEMS CLOSE TO THOSE EXPERIENCED IN PRACTICE

ZUM FLIESSEN DES ASPHALTES UNTER BERUECKSICHTIGUNG PRAXISNAHER PROBLEME

The occurrence of residual deformation in asphalt is a varying type of process. It can be viscous, plastic or viscous-plastic, etc. From large-scale trials using realistic loadings similar to those experienced in highway construction, carried out by the Institute for Construction Materials at the Technical University of Hanover, it was found that the deformation in asphalt is of a plastic nature. With the aid of plastic-theory laws a relation was developed between plastic deformation and comparable stress, which takes into account both the properties of the asphalt material and also its hardening behaviour. With these relations it is possible to show theoretically interesting connections between the depth of a track and the thickness of the bituminous layer and between the depth of a track and the sub-soil conditions. With reference to investigations on "hilpostein" the results have been confirmed in practice. (TRRL)
