Abstract

An attachment for one side of an asphalt paving machine to permit laying of a gutter adjacent to and integral with a roadway surface at the same time as the roadway surface is being paved. The device comprises an extension plate to be vertically oriented in alignment with the screed of the asphalt paving machine and means associated with the extension plate to secure it in this position. The extension plate has a rearwardly curved, L-shaped base extending from side to side along the bottom of the plate for smoothing the asphalt. An end gate is provided at the outer end of the attachment to control the spread of asphalt to the required width. The attachment is intended to be bolted to an automatic screed extension or to the side of the screed of the asphalt paving machine, to replace the screed end gate.
