Abstract

The Road Deflection Tester (RDT) is a testing vehicle for highways capable of assessing a road deflection profile at traffic speeds by using two arrays of laser range finders. The deflection profile in turn is evaluated to determine layer properties in the road structure. The present study looks at some geometric relationships that can be used for this purpose. It was found that evaluation techniques used for stationary devices are less suitable. Other methods may however, be of great value.
