A method and system for guiding a road construction machine using a machine guidance system comprising at least one each of a machine position sensor, a laser-based sensor, and a processing unit. The machine position sensor first measures a position of a road construction machine relative to a road boundary condition. The laser-based sensor then captures a series of scans corresponding to the boundary condition.

A working machine such as a road milling machine of an asphalt paving machine has an automatic grade and slope control system that causes the machine to maintain a pre-selected grade and slope with respect to a reference without significant operator input. A calibration system employs a calibration controller to calibrate the automatic grade and slope control system. The calibration controller causes a current to be sent to a valve that operates a linear actuator that may be employed to change the attitude of the frame of the working machine. The calibration controller uses feedback from at least one sensor, such as a height-measuring sensor or a slope-measuring sensor, in an iterative process that determines the minimum current necessary to cause a change in the attitude of the frame of the working machine. Once this minimum value is determined, the system will establish the optimum settings for the automatic grade and slope control system to improve its efficiency and cause it to operate more smoothly.

Automatic baffle control for truck-receiving hopper of material transfer vehicle
A system and method for automatically controlling the flow of asphalt material from a truck-unloading hopper of a material transfer vehicle into the entry end of an adjacent truck-unloading conveyor in order to optimize at least one vehicle operating parameter includes a baffle mounted to the truck-unloading hopper adjacent to the entry end of the truck-unloading conveyor. The baffle is adapted to increase or decrease the hopper opening into the truck-unloading conveyor. A controller is operatively connected to the baffle and adapted to cause the baffle to increase or decrease the hopper opening into the truck-unloading conveyor. A sensor is provided for detecting at least one vehicle operating parameter. This sensor is operatively connected to the controller so that changes in the at least one vehicle operating parameter can be communicated to the controller. The controller is adapted to control the flow rate of asphalt material into the truck-unloading hopper in order to optimize the at least one vehicle operating parameter.

Method and apparatus for controlling dust emissions with temperature control
A working machine for use in milling the surface of a road includes a drive engine that produces engine exhaust gases. The working machine also includes a milling drum that is mounted for rotation against the surface of the road so as to generate milled material including dust from the road surface. The milling drum is contained within a milling chamber, and a spray assembly directs water into the milling chamber in such a manner that, during a period of rotation of the milling drum against the surface of the road, at least a portion of the water is converted to a vapor. A conduit is provided for conducting at least a portion of the engine exhaust gases into an enclosed space in communication with the milling chamber to raise the temperature of a gas stream therein containing vapor and dust from the milled material.

A broom assembly for attachment to a vehicle is adapted to rotate a brush having a tubular core. The broom assembly includes a center section, a left side plate, a right side plate, an idle hub on one of the side plates and a drive hub on the other of the side plates. These hubs define a core axis about which the brush is rotated. A first linear actuator is adapted to move the left side plate along an axis that is parallel to the core axis between a left open position and a left closed position, and a second linear actuator is adapted to move the right side plate along an axis that is parallel to the core axis between a right open position and a right closed position. The broom assembly may be operated in a work mode and a maintenance mode.
A hopper insert for the hopper of a paving machine is installed above a hopper conveyor that conveys asphalt material in a hopper conveying direction. The hopper insert has a front end and a rear end and a plurality of walls that together define an opening adjacent to the hopper conveyor. The opening to the hopper conveyor increases in width from front end of the hopper insert to the rear end.

A material transfer vehicle for transporting asphalt from a delivery truck to a paving machine includes a frame and a vehicle drive system. The vehicle also includes a turret that is rotatably mounted on the frame and a surge bin that is mounted on the turret. The surge bin has a front side and a rear side with a discharge opening therein. A truck-unloading conveyor is mounted on the frame. The truck-unloading conveyor has an inlet end, and an outlet end which is adjacent to the front side of the surge bin. A paver-loading conveyor is mounted on the turret and has an inlet end extending into the discharge opening on the rear side of the surge bin.
