The invention relates to a road paver or a feeder with a machine frame, a travel carriage powered by a drive unit, and a material hopper with a material retention device arranged in the front in the operating direction, the material retention device comprising a fastening device and a retention element fastened to the material hopper through the fastening device, the material retention device having an overload protection device, which is designed in such a way that in the event of an overload applied thereto the retention element is detached the from material hopper and the fastening device, the latter remaining on the hopper, without damage. The invention also relates to a material retention device of such a road paver or feeder and a method for protecting a material retention device of such a road paver or feeder.

A method of determining optimal frequency to load haul trucks can include a central controller receiving an indication of the amount of paving material at a paving machine, and an indication of production rate of the paving machine. The central controller can then determine when more paving material should be provided to the paving machine. Based on this determination, the central controller can provide alerts or triggers to a paving material plant to indicate when haul trucks should be loaded to provide additional paving materials to the paving machine.

The disclosure relates to a road finishing machine comprising a paving screed for the production of a new road pavement layer of a paving material and a unit provided on the road finishing machine to generate a dynamic compacting specification field based on thermographic geosignals with regard to at least one temperature image that exists behind the paving screed of the road finishing machine for at least one surface section of the newly installed road pavement layer. An information indication unit provided on the road finishing machine is configured to display at last one compacting message that is at least partially based on the compacting specification field to an operator of at least one compacting vehicle that follows behind the road finishing machine for compacting of the newly installed road pavement layer.

Provided is an indirect paddle heater and method for heating asphalt. In one example, the paddle heater may include a control system, a pump to pump heating fluid, a trough that may include an inlet to receive a feed of asphalt mixture and an outlet for exiting the asphalt mixture after heating, and one or more rotational agitators disposed in the trough and comprising paddles attached to shafts that rotate to move the asphalt mixture from the inlet to the outlet, wherein at least one of the trough and the one or more rotational agitators may include hollow channels, and the control system is configured to control the pump to pump heating fluid into the hollow channels when the asphalt mixture is included within the trough.

A melting kettle for processing of thermoplastic material. The kettle disclosed herein obtains heat transfer by use of an oil jacketed tank with an adjoining main tank for storage of hot oil and a hose tank for recovery of the hot oil. Oil expelled from the oil jacket is directed to the main tank through an opening. Spillage of oil from the hose tank is directed to the main tank through an aperture. The melting kettle reduces the space needed for oil storage, and increases operator safety by eliminating additional transfer lines. Dual kettles benefit by having the adjoining main tank placed therebetween.

An asphalt processing system is formed from a heating chamber, a transfer system and an induction heating system. A plurality of paddles, conveyor flights, or conveyor belts having a U-shaped blade move the asphalt through the system while concurrently mixing the material to ensure consistent temperatures through the asphalt cement. The asphalt is heating using one or more induction heating systems to quickly heat the asphalt to between 300° F. and 350° F. The system can include a convection system designed to collect air from the heating chamber, further heat it, and recirculate the air to enhance the asphalt heating. A water condenser can be employed to remove moisture during air recirculation, reducing moisture content in the asphalt cement. The asphalt cement is optionally then modified by addition of one or more rejuvenation oils. This system is particularly useful for recycled asphalt pavement, but can be used for all asphalt products.

A system including a first feeder configured to transport asphalt, a second feeder configured to receive the asphalt from the first feeder, and a controller configured to control a speed of the first feeder and the second feeder in response to an input from an operator.
