A method for seaming artificial turf at its edges is provided. In some embodiments, the method includes providing a tape having a lower surface resting on a support surface, an upper surface underlying the edges of the artificial turf, and a hot melt pressure sensitive adhesive provided on the upper surface of the tape. After application of heat sufficient to soften the hot melt pressure sensitive adhesive, the layer of hot melt adhesive is bonded to the lower surface of the edges of the turf to the tape while the adhesive extends into valleys of the underside of the turf. Also provided is a heating cart for heating the adhesive and a method of using the heating cart to heat the adhesive.

An autonomous earth moving system can determine a desired state for a portion of the EMV including at least one control surface. Then the EMV selects a set of control signals for moving the portion of the EMV from the current state to the desired state using a machine learning model trained to generate control signals for moving the portion of the EMV to the desired state based on the current state. After the EMV executes the selected set of control signals, the system measures an updated state of the portion of the EMV. In some cases, this updated state of the EMV is used to iteratively update the machine learning model using an online learning process.

An apparatus is provided for heating a road surface material to be repaired. The apparatus includes a frame and a heater connected to the frame so as to be positioned over a road surface, in use, for heating for heating a road surface material. An agitator is also connected to the frame for agitating a road surface material. The agitator is configured to agitate road surface material heated by the heater.

The invention involves a low speed control system and method for automatically regulating the speed of work vehicles or equipment and, more particularly, vehicles that apply, remove or modify roadways or road markings. The system includes a controller, a speed display, at least one rotary encoder or the like, and one or more Eddy current or mechanical brakes for inhibiting motion of the vehicle at the operator's control. The brakes may be pneumatic, spring operated, Eddy current, or hydraulic that are controlled in response to feedback from the at least one rotary encoder for compliance with the preset speed on the speed display. In another embodiment, a throttle control is also provided.

Methods, systems, and apparatus are described herein for providing operational efficiency at a construction site through a connected system of on-board mobile computers.

A coating applicator vehicle is configured to selectively discharge a flow of liquid emulsion and aggregate onto a roadway. The vehicle includes a rolling chassis and a powered spraying assembly supported by the chassis. The spraying assembly includes a spray bar assembly including a shiftable spray boom and a plurality of spray nozzles.

A line marking apparatus comprises a body (21) mounted so as to be mobile, a line marking head (29) movable relative to the body, and means (35, 37, 41, 43) for determining the distance travelled by the apparatus from a determined point.

For the construction of synthetic grass playing fields, a plurality of panels (1, 1′, 1″) are manufactured by injection molding and stacked in groups (50). Each stacked group (50) is placed on a distributor vehicle (90) moved along a covering direction (Z), so that the panels (1) which compose the group (50) are able to rotate relative to each other with respect to a main direction (X) orthogonal to the covering direction (Z), so that a row of panels is constructed.
