Dynamic investigations of roads and runways enable the non-destructive observation of the properties in situ of the construction materials down to a considerable depth. The observations can be made at any stage of construction and can serve for recurring control. A survey is given of test results obtained with the road vibration machine on various soils and road constructions. Special attention is paid to the ratio between the modulus of elasticity of successive compacted layers of unbound granular matter.
