Field Compaction Methods for Soils
Vincent D. Reynolds, MBA, P.E.
This one hour
online course discusses the methods involved in Field Compaction for Soils.
The subgrade is the first line of support for roadways, bridges, runways, etc.
It is important that during the placement of earth backfill that the subgrade
be compacted to the minimum requirements as determined by the engineer. This
course will introduce the engineer to the most widely used methods for compacting
subgrades and their importance in the construction of various structures.
This course requires that the readers have access to the following AASHTO or ASTM standards: Standard Test for Laboratory Compaction Characteristics of Soil Using Modified effort, (ASTM D-698 and AASHTO T-180) or Standard Test for Laboratory Compaction Characteristics of Soil Using Standard effort (ASTM D-1557 and AASHTO T-99).
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
At the conclusion of this course, the student would have learned the following:
Intended Audience and Benefit
This course is intended for those wanting an understanding of the basics of soil compaction. It could be especially useful for professionals working in Transportation, site design and geotechnical engineering, as well as construction professionals.
This course is
designed so that the intended audience will benefit immediately with the information
to make intelligent decisions related to soil field-testing.
during the beginning stages of a construction project. The importance of earthwork
cannot be stressed enough as it is the foundation for the remainder of the structure.
The process of earthwork encompasses; Soil classification Mass Hauling, Grading,
foundation construction and Subgrade compaction. In this course we will focus
on the latter.
The course content is in a PDF file (15 K) Field Compaction Methods for Soils. You need to open or download this document to study this course.
The Subgrades is
arguably the most important support for a structure therefore the correct placement
and compaction of soil is essential to a safely designed structure. It is always
suggested to check with a Geotechnical Engineer to specify the correct soil
types and compaction methods for earth backfill. With a properly designed and
constructed subgrade one can rest assure that the remaining structural supports
will be built on solid and sturdy ground.
