Civil engineering society, federal government
honor URI graduate students
Research probes effectiveness of maintenance
and rehab of asphalt
KINGSTON, R.I.-- January 19, 2000 -- The American Society of Civil Engineers
and the Federal Highway Administration have honored two University of Rhode
Island graduate students for their research probing the effectiveness of
different maintenance and rehabilitation strategies for asphalt pavements.
Todd Brayton, originally of Tiverton and now a Newport
resident, and George F. Monaghan Jr., of Cumberland, have been
named the Society's Zone 1 winners of the 1999 International
Contest on Long Term Pavement Performance (LTPP) for their paper, The
Effects of Maintenance and Rehabilitation Alternatives for Asphalt Pavements
in New England and New York.
Zone 1 for the competition covers all of the New England states, Pennsylvania,
New York, New Jersey, Delaware, Maryland and Puerto Rico.
Brayton and Monaghan examined the effectiveness of maintenance and rehabilitation
activities on the Long Term Pavement Performance sections included in the
DataPave software for New England and New York. The two found that maintenance
activities such as crack sealing and patching do serve their intended purpose
of slowing the negative effects of the environment on the pavement by stopping
the intrusion of water.
"It is also shown that rehabilitation activities, hot-mix asphalt
overlays, can effectively improve both the function (roughness and skid
resistance) and structural performance of the pavements," the two said
in their paper.
The pair's work will be available to transportation engineers, transportation
administrators, consultants and contractors.
"Your paper clearly demonstrates the value of using the LTPP Database
to support advances in engineering theory and practice related to pavements,"
the Society said in its congratulatory letter.
Brayton and Monaghan have been invited to publish the paper in a compendium
of selected papers demonstrating uses of the LTPP Databases in engineering
"We congratulate you for your winning effort and thank you for
your contribution toward advancing the effective use of the LTPP Database,"
the society said.
The duo was awarded plaques and a $1,500 cash prize.
Brayton and Monaghan each wrote half of the 22-page paper and the accompanying
30-page appendix. "Todd did a great job tying it all together,"
said Monaghan, a part-time graduate student in civil engineering and vice
president and director of Rhode Island operations for Bryant Associates
in Lincoln. Brayton will join Monaghan at Bryant once he completes
his full-time studies for a master's degree in civil engineering.
"This is the first time URI has won an award of this magnitude,"
said K. Wayne Lee, URI professor of civil engineering and major professor
of the two graduate students. "This puts URI on the national map."
Brayton's and Monaghan's research is part of a 20-year ongoing project
run by the Federal Highway Administration called Long Term Pavement Performance
(LTPP), which is the catalyst behind improving pavement and highway infrastructure
performance. The database software containing LTPP data is DataPave, which
is available to all students, engineers, and practitioners for the international
In addition to co-authoring an award-winning paper, Brayton was also
chosen by the URI Transportation Center as its Student of the Year. "This
is an honor, both for you as well as for the Center in the light of your
outstanding achievements for us," said Daniel W. Urish, URI professor
of civil and environmental engineering and director of the center.
Brayton was also recognized by the U.S. Department of Transportation
during a ceremony on Monday, Jan. 10 as part of the Transportation Research
Board week. The URI Transportation center provided funding for transportation
