ROAD PAVEMENT TESTING BY VIBRATION MEANS

J. Janulevicius, L. Siaudinyte, V. Giniotis

Abstract

Review and analysis of road pavement testing means and methods are presented. Complexity of these methods is pointed out. New approach to pavement testing using vibro-excitation and logarithmic decrement analysis of extinguishing free oscillations is proposed and its advantages are shown.<BR />There are two main groups of methods to find the actual strength characteristics of the pavement: destructive and non-destructive. The latter are divided into static and dynamic types of methods.<BR />Nevertheless, some disadvantages exist in application of<BR />those methods, and a new application of vibration testing<BR />method is proposed.
