  • Drivable device for compacting a soil layer structure and method for ascertaining a layer modulus of elasticity of an uppermost layer of this soil layer structure
    Patent number: 8671760
    Abstract: The present invention relates to a drivable device for compacting a soil layer structure, having at least one vibration means or device, such as a vibration roller or a vibration plate, via which load pulses (P), which compact the soil layer structure, can be introduced into at least one load introduction area. At least one first and one second detection means or devices for detecting the modulus of elasticity of the soil layer structure are provided, which are situated spaced apart from one another on the drivable device in such a way that the first detection means or device allows a detection in the load introduction area and at least the second detection means or devices allows a detection outside the load introduction area. The present invention also relates to a method for ascertaining a layer modulus of elasticity.
