Asphalt paver with compaction compensating system |
摘要 |
An improved asphalt paver with a compaction compensating system includes a nominal reference, such as an elongate averaging ski, for determining the general profile of the underlying terrain on which a mat of asphalt material is being placed by the paver. The improved system also includes a compensating ski for determining localized irregularities of the subgrade and a control system for responsively altering the thickness of the mat being placed by the paver to compensate for differential compaction of the asphalt material such that a generally planar asphalt paving surface is obtained after compaction thereof. Modified embodiments of the improved compaction compensating system include a stringline for the reference and two non-contacting sensors for communicating the general profile and localized irregularity determinations to the control system.
