Engineering Properties of Soils – Chapter 1 – Soil Mechanics

February 13, 2013 in Soil Mechanics



Engineering Properties of Soils

Chapter 1

One of the first steps in civil engineering design is an investigation of soil conditions at the site of the proposed structure.  The engineering properties of soils are important not only as the foundation for the project but also as a construction material for many structures, including roads, embankments, earth dams, and other types of earth-grading projects.  The following topics will be cover: Soil Types, Mass-Volume Relations, Classification Tests, Soil classification, Soil Water, Soil Strength and Settlement, and Test Procedures.

Soils Investigation

Chapter 2

In the evaluation of an area for construction of buildings or other structures, or as a source of construction material, the soil conditions must be investigated before any detailed designs are made.  A soils investigation involves field sampling and testing, laboratory analysis, and preparation of a report.  The planning and evaluation of the field work are aided by a knowledge of the mechanics of soil deposits’ formation. The following topics will be covered; Soil Deposits, Field Investigation Techniques, Laboratory Testing, and Soils Reports.

Aggregates – Chapter 4 – Soil Mechanics

February 13, 2013 in Soil Mechanics




Chapter 4

Aggregates are granular mineral particles used either in combination with various types of cementing material to form concretes or alone as road bases, backfill, etc. Some typical uses of aggregates are portland cement concrete, asphalt concrete, asphalt surfaces, road bases and subbases, railroad ballast, trench backfill, fill under floor slabs, concrete blocks, water filtration beds, drainage structures, riprap, and gabion material.  The following topics will be cover; Aggregate Sources, Aggregates Terms and Types, Aggregate Strength, Properties of Aggregates, Specifications, Sampling and Testing, Blending Aggregates, and Test Procedures.

Compaction – Chapter 3 – Soils Mechanics

February 13, 2013 in Soil Mechanics




Chapter 3

Compacted is used to improves the density and other properties of soil.  Increasing the soil’s density improves its strength, lowers its permeability, and reduces future settlement. The following topics will be cover; Maximum Dry Density, Field Density, Compaction Operations and Quality Control, and Test Procedures.
