From:

Harold Skip Paul, P.E.

Director, LTRC

It is a privilege to share with you the many

accomplishments o LTRC reported herein. First,

you will note that we have changed the period o

the report rom an annual year to a fscal year basis.

As a result, this report actually encompasses 18

months rom January 2007 through June 2008. Iwill let the articles in this report speak or them-

selves and will draw your attention to a ew items

that I would like to highlight in this message.

I had the extraordinary opportunity to par-

ticipate on an international scan tour which took

me rom Stockholm, Rotterdam, Brussels, and Paris

on to Tokyo and Seoul beore returning home.The nine-person team examined practices o

Transportation Research Program Administration,

ocusing on the themes o Setting the Research

Agenda; Partnership Models and Joint Research

Activities; Conduct o Research: Perormance,

Quality and Value; and fnally, Delivery: Getting the

Research Results into Widespread Practice. There

were wonderul lessons learned that will be ap-

plied here at home.

On a closer level, LTRC conducted a very

successul Peer Exchange with peers rom eight

states participating either at LTRC or via video

conerence. Focus areas concentrated on growth

opportunities or LTRC and the establishment o

our new library.

The 2007 Transportation Engineering

Conerence sponsored by LTRC was attended by

over 1,600 transportation proessionals. Over 60

technical sessions were delivered in this very suc-

cessul technology transer event.

Finally, we welcomed Ms. Sandra Brady as ournew librarian and look orward to expanding our

vision in inormation management, and we recog-

nize the leadership that Dr. Marie Walsh brought

to the National LTAP Association while serving as

their President rom July 2007 through July 2008.

It is always gratiying to see sta succeed at the

national level.

Respectully submitted,

Harold Skip Paul, P.E.

Calibration o Resistance Factors Neededin the LRFD Design o Driven PilesPrincipal Investigator: Dr. Murad Abu-Farsakh, Louisiana Transportation Research Center

Co-Principal Investigators: Dr. Ching Tsai, Louisiana Department o Transportation & Development and Dr. Sungmin Yoon,

Louisiana Transportation Research Center

The main objective o this research project is to calibrate the resistance actors needed or implementing the

LRFD design method or both driven piles and drilled shats based on local soil database and Louisiana design

experience.

For LRFD calibration o driven piles, orty-two square precast-prestressed concrete (PPC) piles that were tested

to ailure were included in this investigation. The predictions o pile resistances were based on static analysis, three

CPT direct methods (Schmertmann method, De Ruiter and Beringen method, and Bustamante and Gianeselli [LCPC]

method), and the average o three CPT methods. In addition, dynamic measurements with signal matching analysis opile resistances using CAPWAP, which is based on the measured orce and velocity signals obtained near the pile top

during driving, were evaluated. The Davisson interpretation method was used to determine the measured ultimate

load carrying resistances rom pile load tests. The predicted ultimate pile resistances obtained using the dierent pre-

diction methods were compared with the measured resistances determined rom pile load tests. Statistical analyses

were carried out to evaluate the capability o the prediction design methods to estimate the measured ultimate pile

resistance o driven piles.

Reliability based analyses, using frst order second moment (FOSM) method, frst order reliability method

(FORM), and Monte Carlo simulation method were conducted to calibrate the resistance actors or the dierent pile

design methods used by DOTD. For each pile design method, the target reliability values and the corresponding re-

sistance actors, as well as the e ciency actors, were determined and compared with AASHTO recommended values.

The analysis or drilled shats is in progress.

Peer Exchange Highlights Opportunities or GrowthWhile internal organizational reviews are critical

to progress, periodic critiques rom outside experts can

provide invaluable insight, leading to best practice imple-

mentation. Such is the philosophy behind peer exchange.

In order to manage State Planning and Research

(SP&R) unds, LTRC must conduct a peer exchange every

three to fve years, according to ederal regulations (23

CFR 420 Subpart B). Peer exchange is an opportunity to

review research and development and technology trans-

er activities. Its intent is to strengthen weak programs

while enhancing strong ones.

LTRCs peer exchange team convened in Baton

Rouge or three days in May or an inormal open dia-

logue and exchange o ideas. During the meetings, LTRC

sta presented inormation about current ocus areas and practices, and the invited participants shared their state

practices and took part in brainstorming sessions.

The 2008 peer exchange team included representatives rom Arizona, Florida, Iowa, Mississippi, South Dakota,

Texas, Wisconsin, and Wyoming, along with o cials rom FHWA, LTRC, and DOTD headquarters. With the distance

learning technology available at LTRCs TTEC, remote team members were able to participate in sessions via videocon-

erence. This years peer exchange ocused on the ollowing key areas:Enhancing university relationships

Exploring new research topics

Eectively cooperating with regional peers

Measuring and reporting on the value o research

Developing LTRCs transportation library

The results rom all presentations, interviews, and breakout sessions were compiled into a fnal report that identi-

fed LTRCs strengths in the aorementioned areas as well as opportunities or improvement and growth.

Technical Assistance ProjectsLTRCs technical assistance program provides labo-

ratory testing, feld testing, and orensic investigation

in direct response to Departmental inquiries or expert

analysis on DOTD projects. LTRC also provides assis-

tance to state universities or laboratory or feld testing

on research projects not unded by LTRC. During the

2007-2008 fscal year, LTRC responded to 79 o 80 tech-

nical assistance requests.

Local Technical Assistance Program

LTAP Director Serves as NationalPresident

Dr. Marie

B. Walsh, the

Director o the

Louisiana LTAP,

served as the

president o the

National LTAP

Association

(NLTAPA) rom

July 2007 to July 2008. NLTAPA represents the 58 LTAP/

TTAP state and regional centers to the Federal Highway

Administration and to other external national partners

involved in local transportation management and local

road saety. During her term as president, she was

instrumental in the ormation o the NLTAPA Road Saety

Committee to direct more national-level attention on

the local road saety crisis and to ocus LTAP eorts on

local road saety. Over 60 percent o the nations roadway

atalities occur on rural or locally owned roads, which aremanaged by LTAPs primary customer base. Nation-wide,

LTAP centers are in an excellent position to assist local

customers in improving road saety at the local level and

play a role in driving down the number o deaths on all o

Americas roads.

Dr. Walsh participates in a number o national

road saety committees to represent LTAP and the localtransportation providers. She is also a member o the

TRB Road Saety Work Force Development Task Force

and the Advisory Panel or an NCHRP study on the chal-

lenges and successes o attracting and retaining a skilled

workorce. An active member o the Louisiana team toimplement the Louisiana Strategic Highway Saety Plan,
