  • Publication number: 20160186389
    Abstract: A method to warm a paving machine is disclosed. The method includes activation of a tamper speed control mode associated with a tamper bar in a screed section of the paving machine. A temperature of hydraulic oil of a tamper hydraulic circuit is detected. In addition, a temperature of the screed section is detected. A speed of operation of the tamper bar is set to a predetermined threshold if a temperature of the hydraulic oil is greater than a first oil temperature limit and a temperature of the screed section is greater than a screed temperature limit. The paving machine transitions to a paving mode, if the hydraulic oil temperature exceeds a second oil temperature limit and a minimum operational screed temperature is attained.

  • Patent number: 9200415
    Abstract: A method for preparing a screed assembly for starting a new paving operation is provided. The screed assembly is reset to a pre-stored screed position in response to a user command. A user defined paving depth associated with the new paving operation is received. The screed assembly is positioned to rest on a paving surface and to a float mode in response to a user command. An angle of attack of the screed assembly associated with the new paving operation is set in response to a user command. Further, a height of the screed assembly is adjusted based on the user defined paving depth. A confirmation message indicative of the screed assembly prepared for the new paving operation is provided to a user.

  • Patent number: 8517630
    Abstract: Asphalt paving machine includes screed assembly, plurality of lower and upper plate fasteners, and upper and lower screed plates, each having openings, and an electric heater at least partially disposed between the plates. Upper and lower plate fasteners extend into openings of the respective upper and lower screed plates and bores of a frame portion of the screed assembly to couple the plates to the frame portion. The upper plate fasteners couple the upper screed plate to the frame portion independently of the lower screed plate, so the lower plate is displaceable from the upper plate and the frame portion.
