Soil Stabilization for Pavements
Vincent
D. Reynolds, P.E.
Overview
A well stabilized soil is essential for the
proper function of our roads, bridges, dams, runways, etc. Soil stabilization
occurs during first stages of a project. The degree of soil stabilization could
easily determine the life of a structure. This course will discuss the soil
stabilization methods for pavements.
Due to the non-homogenous nature of soil, it is
common to find soils of different types, stability, compaction, and moisture
content within one project. Stabilizing soils is often required before using the
soil as a sub-base material. Base materials such as gravel and sand are placed
upon the soil before the addition of an asphalt or concrete finished surface.
There are several types of soil stabilization methods that will be discussed in
this course. Using the methods presented herein will enable to student to apply
soil stabilization methods across a broad spectrum of applications.
Chemical additives as well as mechanical
stabilization methods will be discussed. The course covers several government
and non-government testing standards such as ASTM and MIL. Testing methods are
also discussed to give the student further background and resources to determine
the best and most efficient form of soil stabilization.
This 5 hour course will examine the use of soil
stabilization methods for pavements. It will provide useful information that can
be used by the designer, contractor and owner of pavement projects both large
and small.
This course is to be read by anyone with an
interest in soil stabilization, slurry stabilizing methods, chemical composition
of lime, transportation engineering, air pollution, environmental engineering or
anyone wanting to know the several methods used to stabilize soils
The course materials are based solely on the
technical manual “Soil Stabilization for Pavement” as found on the website
of the Army Corps of Engineers. This course includes a multiple-choice quiz at
the end, which is designed to enhance the understanding of course materials.
The student must take a multiple-choice quiz
consisting of thirty (30) questions at the end of this course to earn PDH
credits.
