ABSTRACT:
An improved asphalt paver having a remixing conveyor system that is adapted to substantially or entirely eliminating segregation in hot mix asphalt material delivered to the asphalt paver. The remixing conveying system includes at least one pair of parallelly spaced, oppositely pitched, counter-rotating hydraulically driven feed augers having remixing blades that intermittently displace portions of the hot mix asphalt material generally transversely to the direction that the feed augers convey the hot mix asphalt material from a hopper of the asphalt paver to spreading augers near the rear of the machine. Elongate members over the feed augers provide protection from impact forces and overloading and enhancing lateral extraction of hot mix asphalt material from the hopper. An optional feed screen provides flow control of the hot mix asphalt material in the hopper. A kit is provided for converting existing asphalt paving machines to have desegregating capability. A method is provided for substantially or entirely eliminating segregation in hot mix asphalt material delivered to an asphalt paver.
