16/01: The Foundation for Pavement Preservation has released a
report entitled "Pavement Preventive Maintenance Guidelines
2001", wich contains strategies for initiating, or
improving upon, existing pavement preventative maintenance
programs.

16/01: After
premature rutting failures of Westrack test sections
placed at the track in June 1997 raised concerns about
Superpave mixture design and construction procedures. This
publication was prepared by the Westrack forensic team to
address these concerns. It includes observations on
mixture design compaction level determination,
performance-graded binder selection, and aggregate
selection, followed by extensive discussion of the mixture
design process itself. Laboratory performance tests for
assessing mixture resistance to rutting are also
summarized. Download the report from the Turner-Fairbank
Highway Research Center website at www.tfhrc.gov/pavement/01052.htm.

Following the highly successful CSCE transportation conferences
in Edmonton (1996), Halifax (1998), and London (2000), the
Canadian society for Civil Engineering invites you to submit an
abstract of a paper that you would like to have considered for
presentation at the 4th Transportation Conference to be held in
conjunction with the CSCE annual conference, June 5-8, 2002,
Montreal, Quebec. More information on the call for papers can be
found at http://www.civil.ryerson.ca/events.htm.

16/01: The National Centre for Asphalt Technology
(NCAT)
pavement test track is a 1.7 mile oval facility developed to
test flexible (asphalt) pavement performance in a full scale and
accelerated manner. Experimental sections on the Pavement Test
Track are cooperatively funded by external sponsors, most
commonly state DOT's, with subsequent operation and research
managed by NCAT. Forty-six different flexible pavements have
been installed at the facility, each at a length of 200 feet.
