摘要： A drum mixer for heating, mixing and drying an aggregate material, such as a mixture of recycled asphaltic pavement and virgin aggregate. The drum mixer includes an inclined drum having a first end and a second end. The drum forms a pre-heating/blending section adjacent the first end, a heating/mixing section adjacent the second end, and a heating/drying/mixing section therebetween. A feed assembly for feeding aggregate material, preferably having a high ratio of RAP material to virgin aggregate, is provided. The feed assembly feeds the aggregate material into the pre-heating/blending section of the drum for movement of the aggregate material sequentially through the pre-heating/blending section, the heating/drying/mixing section and the heating/mixing section. A burner assembly extends from the second end of the drum into the heating/drying/mixing section of the drum. The burner assembly creates a high temperature gas stream which flows through the heating/drying/mixing and pre-heating/blending sections of the drum. Longitudinally extending tubular compartments are positioned in the heating/drying/mixing section of the drum so as to define a plurality of longitudinally-extending aggregate transporting channels. The aggregate transporting channels within the tubular compartments are out of direct contact with the high temperature gas stream while the tubular compartments are exposed to the high temperature gas stream. Thus, the aggregate material is heated, and dried indirectly by the high temperature gas stream as the aggregate material passes through the aggregate transporting channels.

摘要： The present invention is a decontamination plant for removing contaminates from contaminated material. The decontamination plant comprises an outer shell including a cavity therein. A drum formed of heat conductive material is rotatably mounted in the cavity defined by the outer shell so as to form an annular heating chamber between the drum and the outer shell. A plurality of heat sources are positioned to discharge heat into the annular heating chamber. The drum also has an inner surface defining a decontamination chamber. A tube is concentrically supported within the decontamination chamber formed in the drum. The tube has an inlet which is in communication with the annular heating chamber so as to receive flue gases therefrom. The outlet of the tube is positioned to exhaust gases from the drum. The drum is slightly inclined from a material receiving opening to a soil discharge end so as to cause the material which is being decontaminated to progress through the decontamination chamber as the drum rotates. While the material is passing through the decontamination chamber, the material is held in contact with the heating drum and the heated tube so as to heat the material via conduction.

摘要： A paving machine having a sensor-controlled concrete metering screed. The machine includes hydraulic cylinders which move the metering screed to various elevations to control the depth of concrete being metered out by the screed. At least one ultrasonic sensor is slide-mounted to the machine above and behind the metering screed to provide measurements of the distance between the sensor and the surface of the concrete just behind the screed. A control system compares the sensor measurements with a tolerance range of distances corresponding to the desired depth of concrete. When the sensor measurements are out of tolerance, the control system moves the metering screed up or down to bring the distance, and the metered depth of concrete, back within tolerance.

摘要： A paving machine having a medially located dowel bar feeder positioned in front of a dowel bar inserter. The machine has a screw or paddle for spreading the concrete and a front strike-off to allocate a proper amount of unconsolidated concrete beneath the machine. Next in line, internal vibrators are mounted to the machine to perform a preliminary consolidation of the concrete, followed by a screed to meter out a correct volume of consolidated concrete for a finished concrete slab. To the rear of the screed, the dowel bar feeder drops dowel bars in a predetermined pattern on the top surface of the consolidated concrete. The dowel bar inserted is mounted to the paving machine behind the dowel bar feeder and includes a plurality of vibrating forks which descend to engage the dropped dowel bars and insert the dowels into the unhardened concrete. In operation, the dowel bars are dropped and the paving machine is driven forward until the forks are over the dropped dowel bars. The paving machine is then stopped and the forks are lowered to insert the dowel bars into the concrete. A finishing machine is operated behind the paving machine to insert center bars and to produce a final consolidated and smoothed grade in the concrete. The paving machine may be adapted to insert dowel bars for transverse joints in a straight or a skewed pattern. In the case of the straight pattern, all the dowel bars for each transverse joint are dropped at the same time. For the skewed pattern, the dowel bars for each transverse joint are dropped one at a time.

摘要： A mixer having an elongated housing with an upper wall, a curved lower wall, an inlet end and a discharge end. A rotatable shaft within the housing extends from the inlet end to the discharge end of the housing. A plurality of blades are attached to the shaft in a discontinuous helical pattern. An injection tube is located at the inlet end of the housing to spray bituminous liquid into the housing. Recycle aggregate and bituminous liquid are introduced into the inlet end of the housing. Asphalt mix is removed from the discharge end of the housing. Each blade has a curved outer end which is in near contact with the lower wall of the housing as each blade moves through a lower part of its rotation. The upper wall of the housing is spaced a distance from the blades to define an open slinging area between the blades and the housing. The blades both mix and move material from the inlet end to the discharge end of the housing.
