Dear Ali,
Some of the early references on compacted fabric are by Lambe. He explained
things in terms of flocculation of clay particles. The aggregation of clay
particles (and other particles held together by the clay) is vital to
understanding compacted soil behaviour. The role of suction in supporting
these aggregations in unsaturated compacted soils has often been overlooked.
Some references on compacted fabric are:

Subject: Soil Compaction Method
Dear all,Hello
Two conventional method to compaction of soil are standard practor and
modified practor. There are some discussion about varying of soil
structure and reduce permeability in modified compaction. Any rational
idea about this matter are welcome.
Best wishes and regards
