Abstract
A compaction compensation system comprising a mechanism for automatically height adjusting the height adjustable mounting (30) so as to height adjust the sensor relative to the screed by a compaction compensating factor. It is used in a paving machine (1) for laying compactable paving material, the paving machine comprising: (a) a height adjustable screed (5) for laying a layer of compactable paving material onto a surface; (b) a sensor (15,17) for sensing the height of the screed relative to a reference level, the sensor being attached to the screed by a height adjustable mounting; (c) a screed height control system for automatically adjusting the height of the screed in response to different heights sensed by the sensor due to contours of the surface, so as to adjust the screed to lay a layer of varying thickness.
