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.
