Patent ID: 7654772

Claim:
In a mobile asphalt production machine having a mobile frame, storage bins supported on said frame to provide a supplies of components materials for the production of bituminous concrete, and conveying devices for transporting said component materials from said storage bins to be combined in the production of bituminous concrete, the improvement comprising: a longitudinally extending mixing auger mechanism supported on said frame to receive said component materials from said conveying devices, said mixing auger mechanism including a ribbon auger rotatably mounted in a substantially horizontal auger tube to mix said component materials received by said mixing auger mechanism including aggregate and liquid bitumen mixed by fins mounted on said ribbon auger to be discharged as bituminous concrete from a discharge end of said auger tube; a burner operable to discharge heat into said mixing auger mechanism at an inlet end to heat directly said component materials while being mixed together by said mixing auger mechanism; and a pothole repair apparatus mounted on said mobile frame and including: a dispensing apparatus for receiving bituminous concrete from said mixing auger mechanism and dispensing desired amounts of said bituminous concrete into a pothole, said dispensing apparatus being controlled independently of said mixing auger mechanism; a heat shield mounted on said mobile frame for positional adjustment to permit positioning of said heat shield over a pothole; and a burner mounted on said heat shield to inject heat energy selectively beneath said heat shield.
