The invention relates to a milling machine (100) comprising a bottom side (11) on which at least two milling heads (1a-1f) are individually movable and controllable in at least one translational movement (15a-15f) in one transverse rail (13a-13f) each, the rails running parallel to one another.

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 blade drive shaft assembly (100) for a road saw comprising a shaft (120), a first mounting plate (125), a spacer removably fitted (126) on the shaft (120), a second mounting plate (127) removably fitted on the shaft (120), a mounting plate fixing adapted to secure the second mounting plate (127) to the shaft, a first circular saw blade mounted between the first mounting plate and the spacer (126), and a second circular saw blade mounted between the second mounting plate (127) and the spacer (126), wherein the first mounting plate (125) is integrally formed with the shaft (120) from a single piece of metal. A road saw incorporating the assembly is also described, as well as a method of forming, filling and compacting a trench and a method of making a blade drive shaft assembly.

A floor cutting machine according to the present invention can comprise: a main frame for supporting equipment required for cutting a floor; a plurality of front wheels positioned at the front of the main frame when the proceeding direction of the floor cutting machine is the front and the opposite direction thereof is the rear; at least one rear wheel positioned at the rear of the main frame; a cutting frame which is a frame separate from the main frame, and of which one side is fixed near the rear of the main frame and the other side vertically moves; a cutting shaft positioned near the other side of the cutting frame; and a cutting blade capable of being fitted into both ends of the cutting shaft.

A floor cutting machine having a dust collection cover coupled thereto may comprise a main frame having a first dust collection cover fixing pin configured to attach the dust collection cover to the floor cutting machine; a plurality of front wheels located at a front of the main frame; at least one rear wheel located at a rear of the main frame; a cutting frame having one side fixed to a vicinity of the rear of the main frame and the other side configured to be moved upwards and downwards; a cutting blade fitted on opposite sides of a cutting shaft located in the vicinity of the other side of the cutting frame; and a front frame detachably connected to the front of the main frame, the front frame having a second dust collection cover fixing pin configured to attach the dust collection cover to the floor cutting machine.

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.

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 working machine including front and rear wheels or a pair of endless tracks supporting a body. A first working arm with a first implement mount is connected to the body. An apparatus with a collector having a first opening and a sweeper trailing the collector is mounted to the first implement mount. A second implement mount connected to the body, and a milling device is mounted to the second implement mount. The sweeper is configured and arranged to move surface material broken up by the milling device into the collector via the first opening.

The present invention is directed to a new and improved asphalt cutter attachment for cutting asphalt surface of a roadway or the like, for example, for facilitating cutting an edge of a roadway or driveway for repairing and installing new asphalt. The attachment includes an elongated baseplate having a top and bottom surface, a plurality of angularly disposed cutting teeth positioned along said bottom surface, and an engagement plate including an engagement channel for receiving the lower edge of an earth moving bucket.
