The invention relates to an edge guard for a road milling machine and to a runner segment for such an edge guard. According to the present invention, the runner segment comprises an insertion projection that can be inserted into an insertion receptacle of the edge guard.

A joint density assembly adapted for use on a screed. The preferred joint density assembly comprises an endgate having a vertical axis. The preferred endgate comprises a frame adapted to be mounted to the screed, a mounting means adapted to mount the frame to the screed, a pivoting shoe adapted to be pivotally adjusted, and a means for adjusting the pivoting shoe which is adapted to move the pivoting shoe between a retracted position and an extended position. The preferred pivoting shoe is adapted to pivot about the vertical axis of the endgate. A method for increasing the density of an asphalt longitudinal joint comprising providing a joint density assembly and adjusting the pivoting shoe.

The present disclosure relates to a control system for a road paver. The control system comprises a camera system configured to generate image data of an environment of the road paver. The control system further comprises a controller electronically connected to the camera system. The controller is configured to receive the image data from the camera system, and to apply an object recognition process on the received image data to identify an edge line serving as a reference line for a mat to be laid by the road paver, and to determine a three dimensional position of the identified edge line. The controller may automatically control the road paver, and may assist an operator to control the road paver based on the identified position of the edge line.

A paving machine that comprises a frame, a driving mechanism coupled to the frame, an asphalt delivery system, a spray assembly coupled to the frame, a pump coupled to the spray assembly, a screed coupled to a back side of the frame and configured to smooth asphalt material applied to the road, and a controller coupled to the driving mechanism.

A joint density assembly adapted for use on a screed comprising an endgate having a vertical axis, a frame mounted to the screed, a mounting means adapted to mount the frame to the screed, and a fixed shoe, a bolt-on unit mounted to the screed and disposed between the screed and the endgate, and a means for adjusting the bolt-on unit between a downward position and an upward position. A method for increasing the density of an asphalt longitudinal joint comprising providing a joint density assembly and adjusting the bolt-on unit.

A telescopic screed includes main section and telescopic section screeds. The main section screed includes a screed frame and a base plate. The telescopic section screeds are arranged on the left side and/or the right side of the main section screed and include a cross slope framework, a cross slope driver, at least two multistage sliding pipes, a telescopic frame, a telescopic driver, a telescopic section frame, a telescopic section base plate and an elevation difference driver. The cross slope framework is pivotally connected with the main section screed to adjust the cross slope. The multistage sliding pipes are used for transversely guiding the telescopic frames to achieve the telescopic ability of the telescopic section screeds. The telescopic section frame is connected with the corresponding telescopic frame to move up and down to adjust the relative height between the telescopic section frame and the telescopic frame.
