Abstract
An improved extendable screed for paving non-coplanar road surfaces with a screed having discontinuous strike plate portions which can be adjusted to define two planes of road surface. The screed is divided into two portions, each comprised of two parts reversibly held together with bolts. The portions may be lengthened by insertion of an extension section in one or both portions. A support system is provided which will allow the support arms of the screed and the pulling vehicle to be connected even though the extended screed is wider than the tractor. The screed and associated support system may be used in a method for paving non-coplanar roads by orienting the screed division-line in line with the center-line of the crown of the road while the center-line of the tractor, corresponding to the center-line of the screw-augers which distribute the paving material to the screed, is oriented with the center-line of the screed, so the augers more evenly draw paving material from each of the paver feeders.
