Abstract
An asphalt layer adapted to be towed after a towing vehicle comprising in combination on the one hand a back wall (6), the lower edge of which determines the upper surface of the layer of material which is laid out, on the other hand a trough-shaped bucket (9) in front of the back wall. The bucket can be turned in relation to the back wall about a horizontal fulcrum (X) parallel to the back wall, and the material in the bucket can be emptied out into the space in front of the back wall. Partitions (39) and (40) or (30) and (31), are disposed in said space and in the bucket to regulate the layer of material to the required width. The first mentioned partitions have a concave front edge which follows on the arc which is generated by the front edge of the bucket when the bucket is turned about its fulcrum. The device (1) may appropriately be connected to a central-pivoted tractor (2).
