Abstract: In one aspect of the present invention, an automatic screed temperature control is disclosed. The control senses the screed temperature and compares the screed temperature to a lower set point. In response to the screed temperature being less than the lower set point, the control causes fuel to dispense into the combustion chamber and subsequently causes the fuel to ignite in order to heat the screed. The screed is heated until the screed temperature becomes greater than an upper set point.

Abstract: In one aspect of the present invention, a control system for a floating screed assembly for an asphalt paving machine is disclosed. The screed assembly includes a main screed and extension screed unit. An electrohydraulic device extends and retracts, as well as, raises and lowers the extension screed unit relative to the main screed unit. The electrohydraulic device additionally pivots the extension screed unit relative to the main screed unit about a horizontal axis. Position sensors produce position signals in response to the position of the extension screed unit. A controller receives the position signals and produces command signals to control the extending, retracting, and pivoting of the extension screed unit to a desired position.

Abstract: In accordance with one aspect of the present invention, a modular screed assembly attachment for an asphalt paving machine having a main screed unit, includes a support assembly that is detachably connectable to the main screed unit, a movable carriage slidably mounted on the support assembly, and a platform assembly movably connected to the movable carriage. The modular screed assembly attachment also includes means for moving the carriage between a position adjacent the main screed unit and a position spaced from the main screed unit, and means for selectively positioning the platform assembly elevationally with respect to the carriage.
