If there is too little material at the auger, what happens to the screed?

When the auger isn’t delivering enough material, there isn’t enough bulk to support the screed at its intended height. The screed sits on the paving mat and relies on a steady flow of asphalt to maintain its elevation; with too little material, the weight and flow beneath the screed aren’t sufficient, so the screed drops slightly and a dip appears in the mat. If the feed were enough or excessive, the screed would tend to stay level or rise, but the described condition specifically causes a lowering of the screed rather than an upward movement or vibration.
