Title: Dynamic Testing of Pavements
Author(s): Gerald Pickett
Publication: Journal Proceedings
Appears on pages(s): 473-492
Abstract:A theoretical analysis is made of the problem of the vibration of a pavement in contact with an elastic su bgrade. The analysis shows that for each frequency of sustained vibration, waves may be propagated horizontally with three different velocities. The properties of the subgrade have little effect on the highest or the lowest of these three velocities but have considerable effect on the in- termediate velocity. Near the origin the velocity of each wave may be greater or less than the velocity farther from the origin. The analysis indicates that the properties of both pavement and subgrade may be determined for any small region of the pavement by placing the source of sustained vibrations in that region.
