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.

Abstract: A machine for texturing a paved road surface on a skew includes a bridge rig spanning the paved road surface in a generally transverse orientation with relation to the generally longitudinal orientation of the paved road surface. The machine includes a carriage assembly, which is supported by the bridge rig for traveling along the bridge rig in its generally transverse orientation. The machine also includes a texturing element, such as a broom, or the like, which is connected to the carriage assembly for texturing the paved road surface as the carriage assembly moves along the bridge rig. By coordinating the movement of the texturing element with the movement of the carriage assembly, the paved road surface is textured on a skew with a transverse tining pattern while the frame of the machine remains square to the paved road surface.

Abstract: A testing apparatus for testing the hydraulic circuits of a vehicle having at least two independent hydraulic circuits including a plurality of supplies conduits, one for each independent hydraulic circuit for receiving hydraulic fluid from the associated circuit, couplings on the supply conduits for coupling each supply conduit to an associated circuit, a return for returning hydraulic fluid to the circuits, a single particle sensor adapted to receive hydraulic fluid and provide an output signal indicative of particle contaminants in the hydraulic fluid, the return being connected to the sensor and a valve for selectively connecting any desired one of the supply conduits to the sensor and disconnecting the remainder of the supply conduits from the sensor so that contamination in any of the independent circuits may be determined with a single sensor.
