In Brief.
Now available are printed copies of four manuals of practice on pavement
repair materials and procedures, originally published as a two-volume
set by the Strategic Highway Research Program and recently updated
by the long-term pavement performance (LTPP) program. Each of the
following manuals includes a discussion of the most appropriate time
to apply a particular treatment, what types of materials and construction
methods should be used, and how to evaluate the performance and cost-effectiveness
of a repair procedure:
- Materials
and Procedures for Rapid Repair of Partial-Depth Spalls in Concrete
Pavements (Publication No. FHWA-RD-99-152)
- Materials
and Procedures for Repair of Potholes in Asphalt-Surfaced Pavements
(Publication No. FHWA-RD-99-168)
- Materials
and Procedures for Repair of Joint Seals in Portland Cement Concrete
Pavement Joints (Publication No. FHWA-RD-99-146)
- Materials
and Procedures for Sealing and Filling Cracks in Asphalt-Surfaced
Pavements (Publication No. FHWA-RD-99-147).
The manuals
also contain step-by-step procedures for ensuring a high-quality repair
and a list of sources for materials and equipment.
A limited number of printed copies of the manuals are available from
the FHWA Research and Technology Report Center, 301-577-0906 (fax:
301-577-1421; email: report.center@fhwa.dot.gov).
Copies can also be downloaded from the LTPP Web site at http://www.fhwa.dot.gov/pavement/ltpp/mofpract.cfm.
The long-term pavement performance program's LTPP Product Plan (see
July 2001 Focus) can now be downloaded from the LTPP Web site at www.fhwa.dot.gov/pavement/ltpp/brochure.cfm.
Looking for an old copy of Focus? An archive of past issues stretching
back to 1995 can be found online at www.tfhrc.gov/focus/focus.htm.
The LTPP program has awarded four new 5-year contracts for the collection
and processing of pavement performance data by region. Data collection
and processing will be handled by Stantec in the North Atlantic region,
ERES Consultants in the North Central States, Fugro-BRE in the Southern
Region, and Nichols Consulting Engineers in the Western States. For
more information, contact Jack Springer at FHWA, 202-493-3144 (fax:
202-493-3161; email: jack.springer@fhwa.dot.gov).
A new study of the performance of pavement edge drains at Specific
Pavement Study (SPS) -1, -2, and -6 sites was recently launched by
the LTPP program. Staff from consulting firm Fugro-BRE will be visiting
the SPS sites this fall to determine the condition of the drains and
whether or not they are working. A report is scheduled to be issued
in Spring 2002. For more information, contact Jack Springer at FHWA,
202-493-3144 (fax: 202-493-3161; email: jack.springer@fhwa.dot.gov).
