Message from the Chair
I am pleased to present the Spring 2004
issue of the CCE Department Newsletter.
As in previous issues, this edition offers
recent Department news, spotlights on
our faculty members, and updates on our
student chapter activities. I feel very honored
and privileged for this unique opportunity
afforded me to keep you informed of the
continuing excellence and growing prestige
of our academic and research programs.
Dr. Joseph W. Tedesco The CCE Department educates students
and conducts research in a variety of areas
related to our state's and nation's needs in constructed infrastructure
and infrastructure systems, hazards mitigation, and environmental
processes. Our faculty are leaders in research in each of these areas,
consistently attracting competitively awarded state and federal
sponsored research. CCE Department research expenditures for
the last fiscal year were nearly $17 million, once again placing the
Department in the top ten nationally among all civil engineering
programs for that category.
To further enhance our research programs, the CCE Department
is moving rapidly forward with the construction of the Powell
Structures Laboratory. The new facility (see artist's rendering
above) will be constructed on the former Florida Department of
Transportation Materials Office site on Waldo Road in Gainesville.
Twelve design/build (DB) firms have submitted proposals for the
project. Final selection of a DB firm is planned for this month.
Construction is scheduled to be completed in the first quarter of
2005.
The CCE Department is also a leader in education. Our academic
program has established itself as one of the most comprehensive in
the nation. For the 2002-2003 academic year, the Department ranked
11th nationally in BSCE degrees conferred, 6th in MSCE degrees
and 12th in Ph.D. Degrees. GO GATORS!
Our faculty continue to distinguish themselves in the civil
engineering profession. Dr. Robert Thieke received the prestigious
2003 ASCE ExCEEd Career Teaching Award, Dr. Trey Hamilton
was elected fellow to the American Concrete Institute, and Drs. Gary


Consolazio and Michael McVay received the coveted K.B.Woods Best
Paper Award at the 83rd Transportation Research Board Meeting in
Washington, DC this past January.
Finally, on a more somber note, the faculty, staff and students of
the CCE Department are deeply saddened by the tragic death of one
of our brightest and most promising graduate students, Sudeer Reddy
Satti. A native of India, Sudeer had recently completed his MSCE
degree and was planning to move to New Hampshire to pursue a
Ph.D. at the University of New Hampshire just a few days after his
tragic death. Sudeer was a brilliant student and an aspiring scholar,
who was admired and loved by his fellow students. During his three
years as a graduate student in the CCE Department, Sudeer made
many friends and became infatuated with American culture. He loved
American sports and was a huge Gator fan. To preserve his memory,
the CCE Department will establish a scholarship in his name (please
see accompanying article on p. 6).
In closing, I want to express my sincere appreciation to our many
alumni and friends for their generous financial support, which
is essential to maintaining the high quality of our education and
research programs to which you have grown accustomed. Your
contributions truly make the difference.

It's great to be a Florida Gator!

CATS: Coastal Area

Tactical Mappin System
Ramesh Shrestha, Bill Carter an C t Slatton
The GEM Research Center
Department of Civil & Coastal Engineering


INTRODUCTION
The United Sates Navy requires timely and
highly accurate imagery of both the surface
and underwater environments in the coastal
zone (CZ) to detect and identify tactical
obstacles and mines while conducting
organic mine counter-measure (MCM)
missions from airborne platforms. The need
for day or night operation, the small target
sizes, and the air-water interface provide
significant technical challenges to the reliable
characterization of submerged features
and must be overcome for accurate target
characterization.
The Department of Civil & Coastal
Engineering (CCE), University of Florida
(UF) was recently awarded a research grant
from the US Navy to develop a unique
coastal area tactical-mapping system (CATS)
for mapping both on-shore and littoral
environments that make up the CZ. The
ultimate goal of the research is to develop a
sensor system for an unmanned aerial vehicle
(UAV) suitable for tactical operations. The
CATS system will be based on Photon
Counting Airborne Laser Swath Mapping
(PC-ALSM) technology and optimized for
low altitude operations (nominally 600 to
1000 meters above local ground level) from
light fixed-wing aircraft. The proposed
sensor will provide a low operating cost
method of mapping both topographic and
shallow water (surf to several meters deep)
bathymetric features of the CZ. The CATS
system will identify and precisely locate
obstacles to tactical operations, day or night,
and even in moderately inclement weather.
It will also be useful for post-strike damage
assessment.

THE TECHNOLOGY
The conceptual design of the PC-ALSM is
based on a high altitude airborne photon-
counting laser altimeter developed at the
NASA Goddard Space Flight Center
(GSFC) that will eventually be deployed
in a satellite. Key members of GSFC
research team, industry partners Optech
International and Dynetics, Inc. will


collaborate with UF researchers on the
design and testing of CATS.
The GSFC work has already shown
theoretically, and confirmed with field tests,
that the conventional high signal to noise
ratio (SNR) approach to ALSM does not
make the most efficient use of the available
laser photons. The effective surface return
rate (density of spatial sampling) can be
increased by up to two orders of magnitude,
for a given laser output power, by emitting
the available photons in a high frequency
train of low energy (few micro-joule) pulses
and using single photon detection, as
opposed to emitting a low frequency train of
high energy pulses and using many photon
pulse detection. Military applications will
benefit from the PC-ALSM systems because
the hardware and power requirements will
make it feasible to operate from a UAV, and
the system will be able to operate day or
night, even in areas of atmospheric haze or
light to moderate fog.


The CATS will use a frequency doubled
NdYAG microlaser. The 0.530 m
wavelength light will penetrate shallow
water and map the bottom out to depths of
about 5 meters, depending on the clarity of
the water. Most coastal defense mines and
obstructions are placed in shallow water. The
CATS system will enable the Navy to assess
the defenses that their assault forces will have
to deal with upon landing, and determine
what actions should be taken to destroy or
remove the defenses before the assault.

CATS CONCEPT
Because the PC-ALSM system will operate
from relatively low altitudes, rather than
from high altitudes, as the GSFC system
did, adequate signals levels can be achieved
with very modest aperture (few cm diameter)
optics. Other advantages of the PC-ALSM
system will include: longer component life
times; small, lightweight, energy efficient
electronics; and eye-safe laser radiation







levels. Overall, the PC-ALSM systems have
the potential to be at least a factor of three,
smaller, lighter and less costly to build
than current commercially manufactured
conventional ALSM systems. The PC-ALSM
sensor developed by this research team will
serve as a proof-of-concept for low-altitude
PC-ALSM, and will be housed in a single-
engine aircraft. However, follow-on systems
will be able to meet size, weight, and power
specifications required to operate from a
small to moderate size UAV with minimal
modifications.

CURRENT ALSM RESEARCH AT UF
The UF is uniquely qualified to develop PC-
ALSM because it already has invested more
than 1.5 million dollars in a conventional
ALSM unit, integrated a high resolution
multi-spectral digital camera into the same
aircraft to collect ALSM and photography
simultaneously, and has used ALSM, digital
photography and ground survey methods
to map many areas in Florida that will be
used to test, calibrate and characterize the
CATS unit. No other academic institution
in the nation has comparable facilities
and experience with combining these
technologies.
Among academic institutions, UF has
led the way in ALSM research for the past
six years. Most notably, it was the only
University invited by the Department
of Defense, Joint Precision Strike
Demonstration (JPSD) Group to participate
in mapping the World Trade Center site
after the Sept. 11, 2001 attack.
UF has operated its own airborne laser
mapping system, jointly owned with Florida
International University, for about five years.
The system has been used in more than
50 projects to support Local, State, Federal
agencies and private companies. The success
of the program has led the National Science
Foundation (NSF) to fund a new Center for
Airborne Laser Mapping (NCALM) to be
operated jointly by UF and the University of
California, Berkeley.
"Our current ALSM system uses return
signals of thousands of photons per pulse
which requires a lot of power," Shrestha says.
Thousands of photons are needed because
the current sensor is not sensitive enough
to detect single photons. The single photon
system, in theory, will be able to detect
every single photon fired that comes back.


The ability to detect a single photon is what
makes the equipment very small," Shrestha
says.
Along with the sensor development,
new computer software will be developed
to processes and analyze the CATS data.
"PC-ALSM technology has the potential
to provide some of the highest resolution
three-dimensional imagery ever acquired
from an airborne platform. These new data
should reveal details of the natural coastal
environment of great value to the Navy,
coastal engineers, and geo-morphologists,"
Slatton says.

SUPPORT FOR CATS
CATS will be a new generation airborne laser
scanning system able to penetrate water in
the surfzone, which could make it invaluable
to Marine Expeditionary Forces (MEF)
needing to detect mines prior to a planned
landing. Based on an initiative sponsored by
Congressman Cliff Stern and Senator Bill
Nelson, the U.S. Congress has provided $2
million for the first year of the program.


EVENTUAL GOAL
The ultimate goal of CATS project is to
deploy in a UAV to provide a method of
high-speed three-dimensional mapping of
surface and submerged surf zone obstacles
in coastal waters including shallow
bathymetric features, and onshore beaches
and adjoining uplands topography. The
CATS observations would also facilitate the
computation of the power spectrum of the
near shore waves. For UAV applications,
the CATS data would be transmitted, via
satellite link or direct radio broadcast, to a
base station for immediate processing. The
three dimensional digital model produced
from the CATS would provide accurate
coordinates for the surface points relative
to the Global Positioning System (GPS)
reference frame. The model could be used
to plan a wide variety of military operations,
including pre-landing bombardment of
obstacles, the detection of mines in coastal
waters, selection of optimal landing sites, and
the location of natural hazards. Ultimately,
the three dimensional spatial information
could be used to create virtual models that
could be displayed inside helmet faceplates.

Innovative Materials Research


Dr. Bjorn Birgisson is spearheading several
teams of UF investigators applying novel,
innovative techniques in civil engineering
materials research. Dr. Birgisson's primary
research focus includes the characterization
and modeling of fracture, damage, and
degradation in bituminous materials and
concrete, as well as other fiber or polymer-
based modifications of these materials.
Since coming to UF, Dr. Birgisson has
developed a long-term research initiative that
integrates advanced material characterization
techniques and numerical simulation
tools into materials research. Recently
completed work in collaboration with Dr.
Reynaldo Roque at UF, and sponsored by
the Florida Department of Transportation,
has led to the development of the first
fracture model to account for both crack
initiation and the discontinuous nature
of crack propagation observed in asphalt
materials. This new model for pavement
fracture has recently been integrated into a
new viscoelasticity-based pavement fracture
simulator. Similarly, collaborative efforts are
underway with the Florida Department of
Transportation to identify the mechanisms
of water damage in flexible pavements.
A significant component of Dr. Birgisson's
concentration is the integration of new
nondestructive testing methods into
material characterization. For example, a
digital X-Ray tomographic imaging system
is being used to characterize the effects of
void structure and aggregate gradation on
the fracture behavior of asphalt mixtures
common to Florida. At the micromechanical
level where fracture initiates, asphalt
mixtures are complex composite materials,
consisting of a matrix of aggregates, binder,


and air voids. Figure 1 shows a typical
horizontal digital X-ray tomography image
of a coarse-graded asphalt mixture.

Based on the knowledge obtained
from the microstructural characterization
of asphalt mixtures, it is possible to
construct micromechanical models of
asphalt specimens. These micromechanical
models are used to simulate the fracture
initiation and crack growth in asphalt
mixtures. Figure 2 shows typical predicted
cracking results from a simulated Superpave
indirect tension test at the point when
cracking initiates and at failure, respectively.
Using the knowledge gained from these
simulations, it is possible to initiate
identification of gradation and aggregate
characteristics that enhance the fracture
resistance of mixtures, and thus minimize
the possibility of premature pavement failure
due to cracking.

In addition to cracking, another distress
mode exhibited by flexible hot mix asphalt
pavements is instability rutting, in which the
material in the wheel path displaces laterally
to form slip planes and ruts in the surface
of the asphalt layer. In this case, failure is
attributed strictly to the asphalt mixture
properties and usually occurs within the top
50 mm of the asphalt concrete layer. Recent
work by Drs. Birgisson and Roque has
shown that high transverse, near surface
shear stresses at low confinement in the
vicinity of the edges of radial tires may partly
explain the mechanism of instability rutting.


K


Figure 3 depicts predicted maximum shear
stress magnitudes and their associated
direction under a typical radial truck tire.
The plotted vectors indicate the formation
of shear planes beneath the loaded area. It
is observed that the direction of the shear
stresses under the first rib of the radial tire
may form shear planes that tend to "shove"
the material away from the tire path. Based
on the results of their work, Drs. Birgisson
and Roque are in the process of developing
a new laboratory test that better captures the
effects of the predicted stress states associated
with instability rutting in pavements.

Finally, Dr. Birgisson has been
collaborating with Dr. Charles Beatty
from the UF Department of Materials
Science and Engineering and Dr. Siobhan
Matthews, from the Dunkalk Institute of
Technology, Dunkalk, Ireland, to integrate
recent advances in nano-modification
of clay/polymer systems and polymer
processing into concrete and asphalt
materials for improved impact resistance and
ductility properties. So far, this research has
been extremely promising, leading to the
development of ductile concrete, in which
the failure strain of concrete is extended
2-3 times greater than that of unmodified
concrete. It is hoped that similar approaches
may also be used for asphalt concrete to
economically enhance its fracture and
permanent deformation properties, resulting
in longer lasting pavements.
