The disclosure is directed towards a system for compacting a work area. The system includes a compactor, a first compaction sensor positioned on a forward end of the compactor, a second compaction sensor positioned on a rearward end of the compactor, and a controller. The controller is configured to receive a first compaction data associated with the work area from the first compaction sensor. The controller is further configured to determine a first compaction effort based on the first compaction data and control the compactor to perform compaction with the determined first compaction effort. The controller is configured to receive a second compaction data associated with a compacted first portion from the second compaction sensor and determine a variance between the first and the second compaction data. Furthermore, the controller is configured to determine a correlation between the variance and the first compaction effort to determine a second compaction effort.

A method and system determines in real time the bearing capacity of a foundation tamped by a high-speed hydraulic tamper. Four wireless acceleration sensors are arranged uniformly along tamping plate edges, sensor position tamping points are determined; the soil is tamped, the plate peak acceleration slows, tends to, and reaches stabilization in a range, a relationship curve between the tamping number and plate peak acceleration is determined; different loads are applied to the foundation to obtain corresponding settlements, coordinate axes are established, points are drawn according to each test data group and sequentially connected with a smooth curve to obtain a settlement-load curve, and the curve is fitted; a tamping number and foundation bearing capacity relationship is obtained; the two relationship curves are combined to obtain a relationship curve, and the foundation bearing capacity magnitude at a certain moment during the tamping operation is determined by using the acceleration index.

A system and associated method constructs a building material from lunar soil. A magnetic sorter magnetically sorts the lunar soil and the system creates a layered surface comprising a microwave susceptible, thermal conductive top layer of lunar soil and a poorly microwave-susceptible and poorly thermally conductive sublayer of lunar soil. A microwave generator generates microwave energy into an antenna and directs the microwave energy onto the top layer of lunar soil to sinter the microwave susceptible, thermal conductive top layer of lunar soil.

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.
