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.

[ What is claimed and desired to be secured by Letters Patent is as follows:] [19.] On an asphalt paver for applying a mat of hot mix asphalt on a surface as the paver is moved along a path, a device for remixing the asphalt material, comprising:a feed hopper for receiving the asphalt material;a spreader arranged to spread the asphalt material in a direction generally transverse to the path to form the mat; anda pair of spaced apart axially rotatable augers disposed within said hopper and extending generally parallel to the path, said augers arranged to convey the material from said hopper towards said spreader, said augers further defining a remixing zone therebetween wherein the material is desegregated laterally relative to the path as the material is conveyed by said augers.
