Abstract: A paving machine is described. The paving machine includes a powertrain with a power unit. The power unit may include a diesel generator and a battery. The powertrain may also include one or more drivetrains. The drivetrains may include a hydraulic drivetrain and an electric drivetrain. The drivetrains may receive power from the power unit for supplying power to actuators of the hydraulic drivetrain and the electric drivetrain. The paving machine may be a curb-forming machine including the battery, the hydraulic drivetrain, and the electric drivetrain. The hydraulic drivetrain of the curb-forming machine may include a cylinder, crawler, steering assembly, and auger, and the electric drivetrain may include a vibrator. The paving machine may also include a number of other types of paving machines. Where the paving machine includes the hydraulic drivetrain, a buffer may be provided to ensure sufficient hydraulic power in response to demand changes.

Abstract: A hydraulic pivot arm positioning assembly includes a forward and aft pivoting arm on both the left and right ends of a paving machine configured to operate in a paving direction. Hydraulic cylinders or other linear actuators enable the forward and aft pivoting arms to rotate automatically through at least a 90-degree range including at least an operating configuration, wherein the pivoting arms extend parallel to the paving direction, and a transport configuration, wherein the pivoting arms extend parallel to the transverse framework of the paving machine, narrowing its overall width. The use of linear actuators enables the pivoting arms to change position with minimal downtime to the paving machine, and without the need for manual repositioning, disconnection, or reconnection of components or accessories of the pivot arm positioning assembly.

Abstract: A modularly configurable paving operations system includes a modular framework extendible or reducible by the addition or removal of frame inserts. A control system can rotate one or more steerable crawlers via a steering assembly to drive, steer, or reconfigure the system. The control system may also include a tining control system, a grade control system, a spray control system, sensors and sensor arrays, and a user interface. The system may accommodate one or more accessories through an undercarriage mounted to the modular framework, which may further include position and elevation sensors and proximity switches. A height adjuster may be configured to raise or lower accessories to maintain a consistent depth or elevation for transverse or longitudinally oriented texturing.

Abstract: A smart steering assembly for a modularly configurable paving operations system includes an end structure at either end of a modular framework. Each end structure has a front and rear adjustable leg with a steerable crawler connected to each leg. A control system can rotate one or more steerable crawlers via the smart steering assembly to drive, steer, or reconfigure the system in response to user input or data received from one or more sensors. Steerable crawlers may be articulated independently or in unison via smart steering cylinders or actuators incorporating onboard sensors connected to the control system. Adjustable legs may alternatively be mounted to the end structure via leg pivots.

Abstract: A modularly configurable paving operations system includes a modular framework of frame inserts, the width of the system extendible or reducible by the addition or removal of additional frame inserts. An end structure at either end of the modular framework has a front leg and a rear leg with a steerable crawler connected to each leg. Individual frame inserts may include a rail system along which end structures, accessories, or components may laterally slide. A control system can rotate one or more steerable crawlers via a steering assembly to drive, steer, or reconfigure the system. The control system may also include a tining control system, a grade control system, a spray control system, sensors and sensor arrays, and a user interface. The system may accommodate one or more accessories through an undercarriage mounted to the modular framework, which may further include a hydraulic height adjuster.
