A portable device for transporting asphalt repair materials for use in repairing potholes in asphalt pavements. The device has a body with a hopper compartment for transporting and dispensing asphalt mix materials. Emulsion oils are held and dispensed from a separate emulsion oil tank. An emulsion pump provides emulsion oils to a spray wand. The emulsion oil tank includes an emulsion rejuvenator apparatus which works to prevent separation of the emulsion oils. A control circuit actuates the rejuvenator any time that the emulsion pump is turned on to supply emulsion oils to a spray wand to spray emulsions onto the road repair site.

A work machine may include a frame supported by a traction device and a power activated steering guide secured to the frame. The power activated steering guide may include a trunk portion arranged and configured to articulate laterally relative to a travel direction of the work machine. The trunk portion may include an actuation mechanism configured to perform articulation and a controller configured for controlling the actuation mechanism to articular the trunk portion to an offset dimension.

A system and method of organizing, managing, and controlling one or more construction vehicles (automated and/or semiautomated) to perform one or more construction tasks within a construction site is provided. The system includes a software platform programmed to control the one or more unmanned construction vehicles via a transmitter and a navigation system. The locations, routes, and general functionalities of the construction vehicles are automatically controlled.

A method for adhering a tubular body onto a surface that includes smoothing a portion of the surface to create a smoothed segment of the surface and applying a tubular body directly onto the smoothed segment of the surface after the smoothing of the portion of the surface. The surface at the smoothed segment is smoother than the remainder of the surface. The method further includes applying an uncured protectant onto the tubular body while the tubular body is on the smoothed segment of the surface and curing the uncured protectant into a cured protectant while the uncured protectant is on the tubular body on the smoothed segment of the surface. The cured protectant protectively encases and adheres the tubular body to the surface.

A construction-vehicle autonomous travel control device to correct a steering angle so as to direct to a target point set on a target track includes: an expected arrival point calculator to calculate an expected arrival point of a vehicle to arrive after a predetermined time based on a vehicle speed and a steering angle; and a corrected steering angle calculator to calculate a corrected steering angle so as to direct the expected arrival point to the target point.

A machine train is composed of a road milling machine that travels in front and a road finisher that travels behind. The road milling machine has a profile data determining device configured so that a sequence of height profile data describing the height of the road surface in the longitudinal direction is determined while the road milling machine advances. For transmission of the height profile data, a data transmission device is provided on the road milling machine and a data receiving device is provided on the road finisher. To change the position of the screed, the road finisher has a levelling device that comprises at least one actuator and a control unit, which is configured so that the control unit generates a control signal for controlling the at least one actuator in accordance with a height profile data set.

The disclosure refers to a container for storing and providing at least one modular road paver assembly designed for detachable mounting on a road paver. The container comprises a storage system by means of which individual components of the road paver assembly can be positioned within the container in a standardized arrangement, such that the components of the road paver assembly can be checked for completeness by an operator by means of a visual inspection along a sequence determined between opposite boundaries of the container in view of their assembly sequence on the road paver.

Disclosed are asphalt binder compositions and methods for making such compositions with pure sterol:crude sterol blends. The sterol blends improve various rheological properties.

A sensor and a method for detecting a position of the sensor relative to a guide surface, comprising a housing and an electronic analysis device which outputs measurement values for the position of the guide surface on the basis of the measurement signals. The sensor contains an ultrasonic transducer array, each of the two outer ends of which is additionally equipped with a respective reference ultrasonic transducer and a respective reflector surface flush with the reference piezo disc at a distance from the base side, said ultrasonic transducers and reflector surfaces being inclined by 45° relative to the base side and pointing towards one another, thus forming a reference measurement path with a known length between the two reference ultrasonic transducers. In the method for detecting the relative position, the measurement values are corrected with respect to environmental influences by measurements in a reference path.

A system for controlling an engagement of a material supply machine with a paving machine is provided. The system includes one or more sensor(s) mounted on material supply machine and/or the paving machine and are configured to detect a position and distance of paving machine with respect to material supply machine. The sensor(s) further detect a relative speed between the two machines. A controller autonomously controls speed of material supply machine based on detected relative speed when distance is less than threshold. The speed of material supply machine is controlled to match speed of the paving machine. The controller also autonomously controls steering of material supply machine based on detected position of leading end of paving machine to align material supply machine with leading end of paving machine until the material supply machine engages with leading end of paving machine.
