An improved extended auger arrangement and an improved asphalt paver with a tractor unit and a screed assembly, including a main screed and extendable screeds, having such an improved extended auger arrangement, the extendable screeds extending laterally outwardly from the main screed such that the screed assembly spans a width substantially greater than the width of the tractor unit. The extended auger arrangement includes a pair of opposing, oppositely pitched, inner augers, rotatable about a substantially horizontal axis oriented perpendicularly to the direction of travel of the tractor unit and approximately spanning the width of the tractor unit, and a pair of oppositely pitched outer augers, rotatable about respective horizontal axes oriented substantially non-perpendicularly to the direction of travel of the tractor unit and approximately spanning the difference between the width of the tractor unit and the width of the screed assembly. Each of the outer augers is drivingly and pivotally connected by a universal joint to a respective one of the inner augers. A supporting structure provides fore-and-aft support for the outer augers.
