Asphalt Paver With Compaction Compensating System

US Patent:
5599134, Feb 4, 1997
Filed:
Sep 15, 1995
Appl. No.:
8/529147
Inventors:
Charles G. Macku - Cedar Rapids IA
Alan W. Boyles - Grand Junction CO
Assignee:
Cedarapids, Inc. - Cedar Rapids IA
International Classification:
E01C 1948
US Classification:
404 841
Abstract:
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.

Method For Compensating Differential Compaction In An Asphalt Paving Mat

US Patent:
5702201, Dec 30, 1997
Filed:
Jul 11, 1996
Appl. No.:
8/679695
Inventors:
Charles G. Macku - Cedar Rapids IA
Alan W. Boyles - Grand Junction CO
Assignee:
Cedarapids, Inc. - Cedar Rapids IA
International Classification:
E01C 1948
US Classification:
404 75
Abstract:
A method for compensating differential compaction in an asphalt paving mat wherein an asphalt paver has a compaction compensating system that 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 and 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. Variations of the method include using a stringline for the reference and/or one or two non-contacting sensors for communicating the general profile and localized irregularity determinations of the subgrade to the control system.
