Free floating screed

The screed is seen at the back of the paver, smoothing the paving mixture under the control of its operator, standing at the center of the screed.

The free floating screed is a device pioneered in the 1930s that revolutionized the asphalt paving process. The device is designed to spread and smooth out, or screed, the material (e.g. concrete or asphalt) below it.
