Webinar - Compaction of Soils and Properties of Compacted Soils

Location: ASCE Continuing Online Education (All times are Eastern Time)
Date: December 18, 2017
Time: 11:30 AM – 1:00 PM

In the construction of highway embankments, earth dams, retaining walls, structural foundations and many other facilities, loose soils must be compacted to increase their densities.  The principal objectives in compacting soil are normally to create fill of high strength and low compressibility, and in the case of water-retaining fill, of low permeability.  This webinar will discuss the conventional (e.g., Proctor) methods of compaction and alternative methods of compaction based on soil air voids and shear strength principles.  Applicability of compaction procedures for various soil landforms (e.g., residual vs transported) soils will be evaluated.  Implications of laboratory tests on field compaction specifications will be discussed.  Properties of compacted soils such as shear strength, volume change, and permeability will be discussed.  Concept of cohesion component of shear strength in compacted soils will be evaluated.
