1. Introduction: Background and Problem Statement
Large deposits of organic soils are encountered across the State of Indiana (Hwang et al.,
2004), with depth of the organics in the tens of feet. Foundations, embankments,
excavations, and other ground works on these deposits become very difficult and often
require costly treatments (Hwang et al., 2003; Santagata et al., 2007). The presence of
deep organic deposits increases the risk of foundation failure or inadmissible settlements.
Also small quantities of organics may affect the engineering properties of subgrade soils
in pavements, rendering them inadmissible for construction.
Figure 1 shows a conceptual cross section of organic soil deposits. Typically a thick layer
of organic soils are encountered first. This is followed by a layer of marl soils and then a
clay deposit. The water table is often found at the surface. Both the organic and marl soils
are characterized by significant amounts of organic.
Figure 1. Cross Section of Typical Organic Soil Deposit
Marl is the classification used for those soils that appear below moderately to high
organic soils and peats. The term marl, also “bog lime”, is loosely used for a variety of
soils, which are generally clay mixed with carbonate or lime. The origin of marly soils
strongly depends on the depth of the water table below the surface and the vegetable
species from which the organic matter of the soils originates. The calcite that may be
present in these soils is produced by precipitation from water saturated with calcium
bicarbonate. Plant roots release organic acids which react with bedrock (limestone,
commonly found in Indiana) and dissolve it increasing the concentration of calcium in
3
the water. Organic carbon content in natural marl soils ranges from 5%-30%. Generally
marl soils form a layer 2 to 72 inches (5-183 cm) thick above the limestone bedrock or
the underlying soil.
The poor engineering properties of organic soils are due to their chemical composition
and interaction with the soil particles. Because of the various chemical components, non-
living organic matter is usually divided into humic and non-humic substances (Hayes and
Swift, 1978). Non-humic substances refer to all recognizable plant or animal debris plus
all of the identifiable classes of organic compounds in their original or transformed
stages. The organic compounds are amino acids (including polypeptides), carbohydrates
(including monosaccharide, oligosaccharide, and polysaccharide), and lipids (including
fats, waxes, resins, and so on) according to Schnitzer and Kahn, 1972. Humic substances
refer to “a general category of naturally occurring, biogenetic, heterogeneous organic
substances that can generally be characterized as being yellow to black in color, of high
molecular weight, and refractory” (Sparks, 2003). These materials cannot be identified as
belonging to an established group of organic compounds. They are further classified as
fulvic acid, humic acid, and humin. Non-humic substances are easily attacked by soil
micro-organisms and exist in the soil for a relatively short period of time (Schnitzer and
Kahn, 1972, Sparks, 2003). Therefore, the term, soil organic matter, is usually used as a
synonym of humus. In a strict sense, soil organic matter refers to compounds that
accompany soil particles smaller than 2-mm (SSSA, 1996).
Fulvic acid is the colored soil organic matter that is soluble in both alkali and dilute acid.
Humic acid is the dark-colored organic matter which is only soluble in alkali. Humin is
the soil organic matter fraction that is insoluble in alkali and remains after extraction of
the humic and fulvic acids with dilute alkali. The distribution of these three fractions of
soil organic matter varies with soil types and depth; however, the elemental compositions
are very similar. They generally include Carbon (C), Hydrogen (H), Nitrogen (N),
Oxygen (O), and Sulfur (S). Humic acids have a typical elemental composition of 54-
59% C, 3-6% H, 1-6% N, 33-38% O, and 0.1-1.5% S. Fulvic acids are composed of 41-
51% C, 4-7% H, 1-3% N, 40-50% O, and 0.1-3.5% S. For humin, the range is very close
to that of humic acid (Schnitzer and Kahn, 1972).
4
Associated with increasing organic content is an increase in natural water content, Liquid
Limit, permeability, compressibility, and a decrease of strength of the soil (Edil and den
Haan, 1994; Edil and Wang, 2000). Because marl soils have a significant organic content,
they are classified as “problem soils”.
Recent work at Purdue University provided a classification for soils with low to moderate
organic content (Huang et al., 2006). The proposed classification consists of two parts,
classification system and screening approach. The classification system divides soils into
four groups: (1) mineral soil (O.C. < 3%) where O.C. is the organic content; (2) mineral
soil with organic matter (15% > O.C. > 3%); (3) organic soil (30% > O.C. > 15%); and
(4) highly organic soil (peat) (O.C. > 30%). Two screening systems were developed, one
for design where the classification is made based on laboratory testing, and the other for
field identification where the classification is done based on simple tests. Figure 2
provides a summary of the recommended field classification for soils with low organic
content.
Figure 2. Field Classification for Soils with Low Organic Content (Huang et al., 2006)
The classification is based on a combination of tests. First the colorimetric test is used on
the soil following AASHTO T 21-05 or ASTM C 40-04, where the soil is mixed with a
5
reactive. If the mixture has a color index smaller than plate No. 3, as defined in the
standard, the soil is classified as non-organic and it is acceptable for use in construction.
If the color index is larger than three, depending on the percentage of fines and liquid
limit ratio (ASTM D4318) the soil is accepted or rejected.
Such classification applies to sandy, clayey, and silty soils, but not to marly soils due to
their content on calcium carbonate and/or lime. The goal of the project is to develop a
classification for marl soils similar to that developed for soils with low to moderate
organic content. The following sections provide details regarding the scope of the
research, work plan, anticipated implementation and benefits of the study, and
organization and budget.
2. Objectives of the Study
The goal of the project is to provide a classification for marl soils similar to that for
organic soils (Huang et al., 2006).
The objectives of the research are:
(1) Provide a classification that expands and is compatible with the classification that
exists for soils with low organic content. The goal is that the final product can be
used seamlessly for any type of organic soil regardless of its calcite or lime content.
(2) Develop clear and simple definitions for marl soils. In the literature the definition of
marl has different meanings, from a rock that is made of calcite and clay minerals, to
a fresh water sedimentary deposit of calcium carbonate (Michigan DOT), to a soft
low-organic soil with calcium carbonate in Indiana.
(3) Prepare recommendations for performing characterization tests on marl soils. Similar
to what was done for organic soils, the objective is to develop recommendations
based on simple laboratory tests that can be used to classify the soils during design
and simple field tests to identify and characterize the soils by the field personnel.
Such classification has proven useful for organic soils and is of interest for marl soils.
These objectives will be pursued through:
6
(1) A state of the art review of the methods and procedures used both in the US and
abroad to characterize and classify marl soils;
(2) In depth characterization study in the laboratory of a number (6-10) of marly soils
sampled throughout the state of Indiana;
(3) Analysis of the results and development of the classification system.
3. Work Plan
The following tasks will be completed in this project:
Task 1: Literature Review
Prior to initiating the experimental work, which represents the core of the proposed
research, a comprehensive literature review will be performed. The objectives of this
phase are to:
- assemble information on classification systems and criteria used for marl soils both in
the US and abroad (with emphasis on countries such as Canada, Russia, Scandinavia,
Ireland and the Netherlands, where organic soils are commonly encountered);
- compile a database with the index properties of a variety of marl and marly soils
available in the literature;
- examine the soil science and agronomy literature for alternative procedures for
characterizing basic properties of marl soils and criteria for their classification.
Task 2: Development, distribution and analysis of survey
As a complement to the literature review, this research project will involve the
development, in close collaboration with the SAC, of a short survey to be distributed
amongst practitioners and selected US Departments of Transportation to get information
on classification criteria, characterization methods, and threshold values used to assess
suitability of a marly soil.
Task 3: Sampling
7
Samples of 6-10 marl soils will be obtained throughout the State of Indiana. These
samples will be chosen to reflect different geography, composition, and nature of the
marl deposits. The number of samples is a preliminary estimate and it is based on the
previous experience gained with the work on the classification of organic soils. The
number may be adjusted as the research progresses.
Three sources of soils are envisioned: natural soil from local geotechnical companies,
from INDOT, and artificial soils prepared in the laboratory. In previous projects
geotechnical engineering companies in Indiana have been an excellent source of soil
samples. Selected companies will be contacted to obtain soil material from their past
projects as well as information pertinent to the sites from where the soils were retrieved.
The second source is INDOT, as on-going soil exploration and construction projects are
potential sources of soil. While there are fundamental differences between natural soils
and artificially-prepared soils, the latter has been successfully used in the past to
characterized unusual soils. The artificial soils are created by an intimate mixture of the
soil constituents; in this case mineral substrate, organic soil and calcium carbonate and/or
lime, with proportions typically found in the field. The preparation procedures in the
laboratory cannot reproduce well nature processes, which through geologic times
accomplish and intimate contact between different chemical compounds at the grain
level. Nevertheless for classification purposes the range of soils obtained from the field
can be expanded using laboratory techniques (Huang et al., 2006; Santagata et al., 2007).
Given the nature of the tests (see section below), undisturbed samples will not be
required. However care will be taken to obtain samples sufficiently far from the surface
so that the results are not affected by surface conditions (e.g. the chemistry of the surface,
run off water, the presence of deicing salts, etc.).
Task 4: Testing and Analysis of Results
Testing of the marl soils gathered through the sampling program will first involve
traditional soil classification tests including particle size distribution, Atterberg limits,
pH, specific gravity, etc., following AASHTO and ASTM standards. It is also of interest
to gain understanding on the micro-structure of marly soils, in particular on the
8
interaction between mineral substrate, organic and calcium carbonate/lime. For this
purpose Scanning Electron Microscope analyses will be conducted on the natural soils.
A specific emphasis of this phase of the experimental work will be the measurement of
the organic and calcite and lime contents of the soils using both loss on ignition methods
as well as alternative approaches such as thermo-gravimetry (TGA) and XRD analysis.
This work will be aimed at assessing under what conditions the LOI provides an
inaccurate assessment of the organics and calcite/lime contents, and possibly identify an
alternative method, or modify available procedures. For example, when the LOI index is
not a good soil descriptor, we expect that a combination of LOI, Atterberg limits and
limited soil chemistry may be used to accurately describe the soil.
The results collected will be analyzed to develop guidelines for classifying marl soils and
recommendations will be made for the methods and the procedures to be used.
Task 5: Report preparation
A final report with the data collected, the analysis of the results and recommendations for
implementation of the findings will be prepared during the last stage of the project.
Throughout the project, in addition to regular meetings with the SAC, timely reports will
be prepared and sent to the SAC to keep all participants informed on the project progress.
4. Anticipated Implementation and Benefits of the Study
The research will complement the recently completed project “classification of organic
soils” (Huang et al., 2006), where a practical classification system was developed for
soils with low organic content. A similar classification system is needed for marl soils,
often encountered with organic soils, which will be provided at the end of the research.
The benefits of the project consist of a unified classification system for the organic soils
encountered in the State of Indiana. With the existing classification, soils with low
organic content, less than 2%-3%, and with low calcium or lime content would most
likely not pass the requirement from INDOT of loss on ignition, and thus could not be
used for some geotechnical applications. Similar to what was found for soils with low
organic content, the loss on ignition may be caused by the clay and the lime or calcite
9
fractions of the soil and so the loss on ignition may not be entirely due to the organics. In
this case the soils could be used for geotechnical applications, which would result in
construction savings. Nayyar Zia will be responsible for implementation of the research
results.
Overall, this proposal addresses a topic that is of interest at the national and international
levels. The impact of the research is therefore expected to be significant also outside the
State of Indiana.

The proposers have an excellent understanding of the problem and nicely differentiate it from the problem addressed in a recently completed project.
The research plan is systematic and addresses the problem with procedures and tests that will likely lead to usable results.
The results of the research will be a classification system for soils with appreciable amounts of marl. It would be good for the project to identify shortcomings associated with these soils and possibly instances on how they may be modified or used.
The PI is exceptionally well qualified to conduct this research and his teaming with two INDOT persons should be advantageous in securing soil specimens and evaluating the usefulness of the results.
The PI might consider having a clay mineralogist on the SAC. Such a person could provide helpful insights.
