The Foundation for Pavement Preservation in cooperation with the Federal
Highway Administration (FHWA), AASHTO and the Lead State team for Pavement
Preservation, has released a CD-ROM entitle "Pavement Preservation:
State of the Practice" as FHWA document FHWA-IF-00-012. The same
information is also available online through the Foundation's website at http:/fp2.org/search.htm.
The CD-ROM contains necessary
information to successfully initiate a pavement preservation program.
Pavement preservation is a relatively new practice involving proactive
maintenance treatments to prolong the life of the pavement.

The second PNS
Snow conference will be held from May 29th to 31st 2001 in Kelowna, British
Columbia at the Grand Okanagan Resort and Conference Centre.
Hosted
by the Insurance Corporation of British Columbia, the
Transportation Association of Canada and the British Columbia
Ministry of Transportation and Highways, the Snow Conference has
been designed to support winter maintenance professionals with
information on current technologies, supplier contacts and
networking opportunities. The first conference was held in June
2000 and received an overwhelming rate of response and support
from its hosts, sponsors and exhibitors.
A
call for speakers and panelists has been made for the May 2001
conference. Visit the conference website at www.pnsconference.com
for more details.

Based on the success of the Strategic Highway Research Program (SHRP) in the
US between 1987 and 1994, the US Congress has requested that the
Transportation Research Board initiate a new process of setting priorities
and designing a program for another focused R&D effort, currently
referred to as Future SHRP (F-SHRP). The study was initiated in January 1999
and is scheduled to be completed by October 2001.
The
most recent F-SHRP update includes candidate research topics.
Visit the F-SHRP website at http://www4.nationalacademies.org/trb/newshrp.nsf
for more details.

The 2000 Annual Conference of the Transportation Association of Canada (TAC)
will be held from October 1-4 in Edmonton, Alberta. The theme
for the conference is "Transportation, Trade, Tourism and
Technology". C-SHRP will be in full force, participating in
the exhibition, as well as the technical sessions. Be sure to
attend on Wednesday, Oct. 4 for "C-SHRP -- The Road from
Research to Implementation: LTPP Results in Canada and the U.S.

The Truck
Pavement Interaction (TPI) research program was initiated by the Federal Highway
Administration (FHWA) in the mid 1980's to develop advanced methodologies and
technologies that would allow a better understanding of the interactions between
heavy vehicles, climate, and pavements. The research includes pavement response,
damage, performance and vehicle dynamics. The primary goal of the research is to
achieve increased productivity through optimization of infrastructure
strengthening and the introduction of road-friendly truck fleets.

The Virginia Smart Road is a state of the art full scale
test facility for the testing, evaluation and verification of Intelligent
Transportation Systems (ITS) concepts, technologies, and products. Research
projects will include the analysis of:
i) crash avoidance technologies
ii) driver behaviour
iii) vehicle dynamics
iv) ITS sensors
v) pavement testing
vi) automated vehicle control
vii) snow and ice removal
The main objectives of the pavement
research at the Smart Road are SuperPave mix evaluation, calibration of pavement
response to FWD testing, GPR signal interpretation, and initial research on
pavement performance prediction.
Get
more information concerning the Virginia Smart Road through the Virginia
Tech Center for Transportation Research at http://www.ctr.vt.edu/research_tools/smartroad/.
Information specifically concerning pavement research at the Smart
Road can be found at http://cesun1.ce.vt.edu/tise/smart/index.html.

The results of a
survey conducted on behalf of the AASHTO Anti-Icing/RWIS Lead
State Team are available through the Iowa Department of
Transportation website at http://www.dot.state.ia.us/winter.htm.
The
1999/2000 survey was completed to measure the success of the
Lead State Team’s efforts to transfer anti-icing and road
weather information system (RWIS) technologies into mainstream
practice since its inception in 1996. The resulting report is entitled “1999/2000 Technology and
Usage Survey Results: Anti-Icing Techniques and Road Weather
Information Systems Technologies.”
Since the 1997 baseline survey, the reported use of
anti-icing strategies rose from 79% to 90% and the number of
states with rate application guidelines rose from 43% to 60%, a
clear testament to the dedication of the Lead State Team.
Through
cooperation with C-SHRP, the 1999/2000 survey was also sent to
each of the representatives of the TAC Chief Engineers Council
to provide Canadian input to the survey.
A total of 32 Canadian responses representing each of the
10 provinces were collected and the report includes a separate
section outlining the Canadian implementation of anti-icing and
RWIS technologies. Special
thanks to Dena Gray-Fisher of the Iowa DOT for including the
Canadian data in the survey.

The
National Center for Asphalt Technology (NCAT) has recently
released a white paper concerning the tender zone phenomenon
often experienced with Superpave mixes.
The paper describes the tender mix problem, discusses
probable causes, and offers steps to prevent mix tenderness.
The white paper can be downloaded from the NCAT website

The first
conference of the Pacific Northwest Snowfighters (PNS)
was held in Kelowna, BC from June 12th to 14th. The Snow Conference 2000 was the first conference organized
by the PNS and was a smashing success on all fronts. Over 500 delegates and 150 exhibitors descended on Kelowna to
discuss the latest technologies in snow and ice control.
The conference was hosted by the Insurance Corporation of
British Columbia (ICBC), the
Transportation Association of Canada (TAC)
and the British Columbia Ministry of Transportation and Highways
(BC MoTH).
Dr. Roberta Bondar, Canada’s first woman to travel into outer space, provided
an excellent keynote address to officially open the conference.
In addition to technical sessions, delegates also put their skills (or
lack there of) to the test at the Equipment Obstacle Course, driving anti-icing
trucks around the trade show parking lot against the clock.

June
20/00: The
3rd Transportation Specialty Conference was held as
part of the 2000 Canadian Society for Civil Engineering (CSCE)
conference in London, Ontario from June 7th to 10th.
Approximately 600 delegates, primarily from academia,
attended the conference to hear the latest news in Civil
Engineering, obtain information from the 29 technical
exhibitors, and network with their peers.
As
part of the Transportation Specialty Conference, C-SHRP hosted a
technical session entitled “The Canadian Strategic Highway
Research Program: Past, Present and Future” to review some of
the program’s past achievements, current status, and future
activities. Also
presented were the results of the recent C-LTPP Roughness Trends
report and the soon-to-be-released C-LTPP Surface Distress
Variability Analysis. The
session was well attended and generated healthy discussion.

As part of its
expanded technology transfer mandate, C-SHRP has launched an
independent website at www.cshrp.org.
The new site contains many improvements including updated
program activities, the online version of the C-SHRP Directory
of Superpave Resources, and a much improved C-LTPP section
featuring maps of the test site locations.
Be sure to visit the site often, as program
activities will be continually updated on a regular
basis. An online version of the C-LTPP database is
also under development and will be available this fall.

Key Findings from LTPP Analysis: 1990-1999 highlights some of the key findings from LTPP analysis studies. Approximately 50 documents were reviewed to
develop this summary to provide LTPP partners with information that can help them in their quest to design, build, and maintain cost-effective and long-lived roads. These findings have been organized into the following topical areas: Site Conditions, Structural Features, Materials, Initial Roughness, Pavement Maintenance, Pavement
Rehabilitation, AASHTO Design Validation, and Performance Modeling.
