A rotor assembly includes a generally cylindrical rotor having a drive end and a bearing end opposite to the drive end. The rotor is rotatable about a longitudinal axis. The rotor assembly further includes a transmission contained substantially within the rotor at the drive end. The transmission has an input shaft and an output shaft offset from the input shaft. The output shaft is operatively coupled to the rotor and is coaxial with the longitudinal axis of the rotor. The rotor assembly further includes a bearing assembly contained substantially within the rotor at the bearing end. The rotor assembly has a mounting axis and a bearing axis offset from the mounting axis. The bearing assembly further has a rotatable bearing operatively coupled to the rotor and is coaxial with the longitudinal axis of the rotor.

A multilayer integral geogrid, including one or more cellular layers, has a plurality of oriented multilayer strands interconnected by partially oriented multilayer junctions with an array of openings therein. The multilayer integral geogrid having one or more cellular layers is produced from a coextruded or laminated multilayer polymer starting sheet. The integral geogrid has a multilayer construction, with at least one outer layer thereof having the cellular structure. By virtue of the cellular layer structure, the multilayer integral geogrid provides for increased layer vertical compressibility under load, resulting in enhanced material properties that provide performance benefits to use of the multilayer integral geogrid to stabilize and strengthen soil, aggregates, or other particulate materials.

Described herein are tools, systems and methods for conditioning, strengthening and/or improving in situ soil geotechnical or agricultural properties while at least temporarily reducing soil density, energy requirements, and tool wear.

In a device for working ground surfaces or roadways comprising a machine frame and a working drum in a drum housing arranged at said machine frame, where no less than one spraying device extending parallel to the working drum and featuring several outlet nozzles for spraying agents arranged next to one another and directed towards the working drum is arranged at the drum housing, where the outlet nozzles comprise one each drivable closing mechanism with a closing element which, in an open position, fully uncovers the nozzle channel of the outlet nozzle and, in a closed position, closes the nozzle channel, it is provided for the following features to be achieved: that a controller drives the closing mechanisms, with the outlet nozzles and the related closing elements being adapted to one another in such a fashion that the flow cross-section in the outlet nozzle is variable in accordance with the position of the closing element on a specified path between the open position and closed position.

A method of underground watering utilizes a pouch-like container product made by joining a first sheet having SAP particles adhered to a first surface with a second sheet to form a container partially filled with such particles. The application of pressure, for example by passing the product through a roll nip, facilitates joining of the sheets and causes the particles to break through at least the one of the sheets to create an opening whereby free volume is created to permit the particles to expand when in contact with a liquid. The resultant product is used to collect, store, and dispense water-containing liquids into the soil for watering of agricultural plants, trees, and the like. A composite underground watering element is also included in an embodiment of the invention. The inventive products may also be used as a pad, including a propagation pad, to collect, store, and dispense water-containing-liquids into plant vessels to provide watering of plants. Also included are underground watering of athletic fields and golf course greens, erosion control products and plant root balls having a watering collar.

A milling machine has a frame, a rotor, a mixing chamber with a front door and a rear door, and a controller. The controller is in communication with the frame, the rotor, the front door, and the rear door, and configured to operate the milling machine in a travel mode and a work mode. When the travel mode is actuated, the controller raises the rotor to a predetermined position, closes the front door and the rear door, and raises the frame to a predetermined height. When the work mode is actuated, the controller lowers the frame to a predetermined height, lowers the rotor to a predetermined position, and opens the front door and the rear door to predetermined positions.

A multilayer integral geogrid, including one or more cellular layers, has a plurality of oriented multilayer strands interconnected by partially oriented multilayer junctions with an array of openings therein. The multilayer integral geogrid having one or more cellular layers is produced from a coextruded or laminated multilayer polymer starting sheet. The integral geogrid has a multilayer construction, with at least one outer layer thereof having the cellular structure. By virtue of the cellular layer structure, the multilayer integral geogrid provides for increased layer vertical compressibility under load, resulting in enhanced material properties that provide performance benefits to use of the multilayer integral geogrid to stabilize and strengthen soil, aggregates, or other particulate materials.

A multi-axial geogrid possesses a series of interconnected strands or ribs that are arranged along at least two different axes within the plane of the structure. The strands or ribs have an aspect ratio, defined as the ratio of the thickness to width, of greater than 1.0, thickness being the direction normal to the plane of the structure. The geogrid can be manufactured by modifying the process parameters in order to create high aspect ratio ribs, using any of the various known methods for producing geogrids. A reinforced civil engineering structure, and method therefor, is formed by embedding in soil one or more horizontal layers of geogrid having high aspect ratio ribs. The reinforced structure shows improved rutting performance when subjected to vehicular traffic.

System and means soil stabilization and moisture control for building foundations including methods and systems for stabilization moisture in a site for building foundation by applying soil moisture stabilization material in various forms, a preferred stabilization material being a mixture of aluninosilicate Pozzolan mineral and granular material such as sand.

A soil stabilization mixture comprising a mixture of soil to be stabilized, fibers and binder. The soil and the fibers are mixed together. The binder, which acts as a chemical stabilizer, is then added and mixing continues. The mixture is then applied to the soil to be stabilized and the stabilized soil is then compacted. The fibers can be recycled carpet fibers, fiber reinforced polymer, biofibers or a mixture thereof. The binder includes mixtures of Portland cement and at least one of crushed glass, metakaolin and ground blast furnace slag.
