A self-propelled roadway crack routing machine has an operator's station located on a front portion of the machine's chassis and including a forward-facing operator's seat. A driven crack routing cutter drum for routing cracks in a roadway surface is mounted on the front portion of the chassis in a location that can be monitored by a forward-facing operator while controlling machine steering and propulsion. The machine includes a steered rear wheel and unsteered front wheels. Machine steering and propulsion and implement operation may all be effected hydraulically.

A machine for backfilling pavement material into a trench defined within a pavement surface includes a frame defining a longitudinal axis and having at least one wheel. The frame being configured to move along the pavement surface. A hopper supported on the frame and including an inlet opening configured to receive pavement material and an outlet opening configured to discharge pavement material into the trench. The machine also includes a compactor supported on the frame and aligned with the hopper along the longitudinal axis. The compactor is configured to compact the discharged pavement material within the trench.

The present disclosure provides various aspects for mobile and automated processing utilizing additive manufacturing. The present disclosure includes methods for adding strengthening features to a roadway surface. In some examples, the strengthening features may include fibers, nanofibers and nanotubes as examples.

A pavement joint sealing system that meters out an appropriate amount of sealant over potentially varying speeds and especially with potentially varying joint dimensions. Given the joint dimensions, the system is able to determine and enforce an effective ratio between the applicator speed and the sealant flow rate.

A microtrench gravel installer configured to install gravel into a microtrench at a precise gravel layer thickness using a gravel leveler and/or a premeasured gravel box. A hot patch fill wand and box surrounding the wand configured for installing a hot patch fill sealant into a microtrench. A method of filling and sealing a microtrench containing an optical fiber and/or innerduct/microduct using the microtrench gravel installer to precisely fill a microtrench to a desired gravel layer thickness.

The robotic maintenance vehicle (RMV) has a propulsion system, a control system, an electrical power source, a maintenance module, a multi-axis robot, an optical system, and a location translator. The maintenance module is configured to hold different kinds of road maintenance materials. The multi-axis robot is configured to convey the road maintenance material from either the maintenance module to the road, the road to the maintenance module, or both. The optical system and the location translator are configured to be controlled by the control system and operate in conjunction to instruct the multi-axis robot where to pick up and/or place the road maintenance material. The multi-axis robot is configured to be selectively coupled to a distal arm tool.

A concrete removing apparatus comprises a claw, a cleaving blade, and a bracket. The claw generally has a lower portion, a back portion, and an upper portion. The lower portion generally has a bottom surface, a sloped top surface, and extends forward from the back portion. The upper portion generally extends forward from the back portion partially overhanging the bottom portion and forming a locking notch defined by a front edge of the back portion, a bottom surface of the upper portion, and the top surface of the bottom portion. The cleaving blade is generally attached to a rear surface of the back portion of the claw. The bracket is generally mounted on a top surface of the upper portion of the claw and configured to pivotally connect the bracket to an arm and a hydraulic cylinder of a construction machine.

A concrete cutting machine, for wet and dry dual-use cutting, includes a saw blade, which is configured to cut concrete, a motor, which is configured to drive the saw blade to rotate about a first axis, and a bottom plate, which is configured to support the motor and the saw blade. The bottom plate is formed with a first cutting space for the saw blade to pass through. The concrete cutting machine further includes a sliding plate assembly, which is at least partially disposed in the first cutting space, to form a second cutting space smaller than the first cutting space.

In some aspects, the techniques described herein relate to a passenger motor vehicle including a robotic arm configured for use in performing an additive manufacturing operation. A method is also disclosed.
