This paper presents four grouting techniques – compaction, permeation, jet and soil fracture – that have particular relevance in today's global construction marketplace. A brief introduction to each technique is followed by discussion of recent advances, illustrated by case studies...

This paper presents the measures used to control the compaction and settlement of the fill embankments, as well as the results of field...

[email protected]. PENETRATION TEST COUPLED WITH GEOTECHNICAL CLASSIFICATION FOR COMPACTION CONTROL. Chaigneau L.1, Bacconnet C.2,Gourves R.3 ABSTRACT. A penetrometric test under taken in a well-known granular medium (particle size distribution and water content) is directly linked with the dry...
