A B S T R A C T The asphalt laying machine comprises a rear body di- vided into sections with smoothing and compacting units sus- pended through vibration dampers in the frame. Each unit comprises an intermediate part and a smoothing part inter- connected by means of a rear shaft bearing and a front con- necting rod connected to an eccentric. By virtue of this interconnection an elliptical movement is transferred to the smoothing part during operation of the machine, and this movement produces a heavy tamping at the front edge, a smoothing and vibrating effect at the intermediate area of the ironing plate, and a succeeding tamping and polishing effect at the rear edge area. The tamping foot of a scraper plate suspended on the intermediate part tamps laid asphalt syn- chronously in opposition to the tamping plate of the ironing plate by virtue of reaction forces transferred through the intermediate part. During the operation of the machine,the smoothing and compacting unit ensures an unusually densely compacted and uniform surface of the asphalt.
