Abstract:

The placement of utility pipes normally necessitates many cuts and fills of the existing pavements. Integrity of pipeline and compatible performance of cut restoration and original pavement depends on the proper reconstruction of cut region. In this study a theoretical analysis has been performed to determine which conditions of restoration; such as poor compaction of soil subgrade, base or asphalt layer, have the potential to affect performance and integrity of pavement and pipeline, and also to determine which factors are potentially more important. A total of 60 cases consisting of different combinations of layer properties, layer thicknesses and cut width have been studied for this purpose.
