Systems and methods to provide pressed aggregate-filled cavities for improving ground stiffness and uniformity are disclosed. According to an aspect, a method includes using a mechanism to press into a ground surface in a substantially downward direction to create a concavity. The method also includes substantially or completely filling the concavity with unstabilized or chemically stabilized aggregate, soil, or sand. Further, the method includes using the mechanism to press the aggregate within the concavity to achieve a desired ground stiffness.

The flexible strip of a polymeric material includes reinforcing elements and protrusions located on a surface of the strip. The reinforcing elements are placed to contact the surface of the strip and embedded at intersections between the protrusions and the reinforcing elements. A method for producing the flexible strip of a polymeric material includes extruding the polymeric material for producing a flat preform, laying the reinforcing elements onto a preform surface, processing the preform in rolls for forming protrusions on the preform surface, cutting the preform into strips. In the step of processing the preform, the reinforcing elements are embedded into said protrusions at the intersections between the protrusions and the reinforcing elements.

A feedstock processing apparatus for applying, distributing, and compacting feedstock in defined layer heights may include a chassis with a traction drive and a first and second undercarriage, a frame structure that connects the two undercarriages over a span width of the feedstock processing apparatus, a material feeding device coupled to the frame structure, a material distributing device coupled to the material feeding device and displaceable in certain sections over the span width and configured to apply the feedstock in layers on soil in different, predefinable height positions between the undercarriages, and a compacting device displaceably mounted on the frame structure and/or the material distributing device. The compacting device and the material distributing device can be displaced in a manner dependent on one another respectively along a predefinable movement path. A corresponding method is also disclosed.

A method for providing information related to the compaction state of a soil when performing a compaction operation with a soil compactor comprises the operations: a) detecting a vertical acceleration and a horizontal acceleration of a vibratory roller when moving a soil compactor over a soil to be compacted, b) determining a measurement relationship between a ground contact force (F.sub.b) and a deflection (s.sub.w) of the vibratory roller for one vibration cycle using the vertical acceleration and horizontal acceleration detected in operation a), c) determining a simulation relationship (Z.sub.S) between the ground contact force (F.sub.b) and the deflection (s.sub.w) for one vibration cycle using a ground model taking into account at least one simulation parameter, d) comparing the simulation relationship (Z.sub.S) to the measurement relationship, e) determining that a default value of the at least one simulation parameter taken into account in the ground model substantially represents a corresponding soil parameter of the soil to be compacted when the simulation relationship (Z.sub.S) substantially corresponds to the measurement relationship.
