A work machine may include a frame supported by a traction device and a power activated steering guide secured to the frame. The power activated steering guide may include a trunk portion arranged and configured to articulate laterally relative to a travel direction of the work machine. The trunk portion may include an actuation mechanism configured to perform articulation and a controller configured for controlling the actuation mechanism to articular the trunk portion to an offset dimension.

An installation system has a laser range finder set at a reference position to measure a distance to a target, an installation cart which performs operation for laying a magnetic marker in a road, and an arithmetic unit which identifies a position relation of a laying position where the magnetic marker is laid with respect to the reference position. When operation for laying the magnetic marker in a road is performed, by taking the installation cart during performing the operation of laying the magnetic marker in the road as a target, based on a distance to the installation cart measured by the laser range finder, the position relation of the laying position with respect to the reference position is identified by the arithmetic unit.

The present disclosure provides various aspects for mobile and automated processing utilizing additive manufacturing. The present disclosure includes methods for adding line features to a roadway surface. In some examples, the line features may include wires, conduits and electronic components. In some examples, the mobile additive manufacturing apparatus may create communication means into an advanced roadway in line features, which may be used for various communications including communications to and from autonomous vehicles. The communications may involve data related to the operation of systems of autonomous vehicles. In other examples, the line features may be dynamically colored with LED components.

A holder (1) for fixing a cylindrical spray can (2). The holder (1) comprises a holding unit (3) for fixing the spray can (2) with a first mechanical interface (4) for connecting a GNSS receiver (5) or prism to the holding unit (3). The holding unit (3) is adapted to hold the spray can (2) such that the GNSS receiver (5) or prism and the spray can (2) are arranged coaxially to each other. The holding unit (3) comprises a second mechanical interface (6) for releasably connecting the holder (1) to a frame (7) of a surveying cart (8).

A hot applied thermoplastic pavement composition and method of using a hot applied thermoplastic pavement composition includes a modified polyamide resin in the range of between 3 and 10 percent by weight, wherein the composition contains rosin-modified esters, a copolymer, 30-70 percent by weight of a glass bead intermix, a range of between 1 and 15 percent by weight of either white or yellow pigment, the balance of the composition being selected from the group consisting of one or more plasticizers, inorganic fillers, waxes, antioxidants and light stabilizers.

A diagnostic vehicle (1) which diagnoses operation situations of magnetic markers (10) laid in or on a traveling road so as to be magnetically detectable by a vehicle includes sensor unit (11) which obtains a one-dimensional magnetic distribution by measuring a magnitude of magnetism with which any of magnetic markers (10) acts therearound, line sensor camera (13) which obtains a marker image, which is one-dimensional image information, by imaging magnetic marker (10), and diagnosing unit (15) which determines the presence or absence of a flaw in magnetic marker (10) based on a comparison between a magnetic distribution and the marker image.

A ground marking apparatus is configured to apply marking material to a ground surface. The ground marking apparatus includes a beam supported by a beam mount and extending along a beam axis. A carriage is disposed on the beam and movable on the beam along the beam axis. A carriage motor operably interfaces with the beam and is configured to move the carriage along the beam. A dispense arm is supported by the carriage and is configured to move relative to the beam as the carriage moves along the beam.

Starting from a set of plans, such as, without limitation, blueprints, drawings, or Autocad® files, a system and method for calibrating such plans and transferring such plans into a computer readable file and loading a specially designed electronic version of such plans into a hardware based system that locates, adjusts, transfers, and prints, to a desired scale, a lasting image of said construction plans drawn onto a building surface.

A texturing machine is provided for the subsequent treatment of a freshly produced concrete layer having a width between left and right edges and extending longitudinally in a working direction. Left and right height sensors are arranged to detect a height above the freshly produced concrete adjacent the left and right edges of the layer. At least one crown height sensor is arranged to detect a height above a crown of the freshly produced concrete layer. A controller is configured to receive input signals from the height sensors and to communicate height control sensors to the height adjustable columns and to communicate a crown control system to the crown actuator. A direction sensor may also detect at least one of the edges of the freshly produced concrete layer. The controller may receive a direction input signal from the direction sensor, and the controller may communicate a direction control signal to a steering actuator of one of the ground engaging units of the machine.
