Whitetopping has always
been eligible for funding
In response to several recent inquiries
about airfield whitetopping projects, ACPA is distributing an
important message to the design and construction community: Whitetopping
projects are and always have been eligible for Federal
Aviation Administration (FAA) funding, and if selected, the
FAA P-501 concrete pavement specification needs only minor modifications
to accommodate a whitetopping project.
FAA's official position on
whitetopping has been in print
for many years. Paragraph 410 of the FAA Advisory Circular
on Airport Pavement Design, AC
150/5320-6D, includes concrete overlays on flexible
pavement, for example conventional whitetopping, as a viable
pavement design option.
The Advisory Circular even provides
thickness design curves for determining the whitetopping thickness.
The concrete pavement designer,
specifier, and constructor need to be aware of certain aspects
of whitetopping design and construction that differ from new pavement.
The FAA specification for concrete pavement, P-501, found in the
FAA Advisory Circular on Construction Specifications,
AC 150/5370-10A, needs minor modifications to work well with
Changes should be
made in the measurement and acceptance criteria, and the changes
should address thickness variability and material quantities.
The concern about thickness can be resolved by milling the existing
asphalt to a uniform profile, however, this step adds cost and
is not necessary. The specifications for most whitetopping projects
are modified to address the thickness variability and to allow
acceptance of concrete by the cubic yard with a unit cost for
placement by the square yard.

Features Newest Grinder
a registered trademark of the International
Surface Preparation Corporation, recently introduced
the BG 250, the company's latest surface grinder.
BG 250 is a 10" high production surface grinder used
for concrete cleaning, leveling, and removal of mastics,
epoxies, urethane, paint and other coatings. It can
be used for leveling out high spots and curled joints.
walk-behind grinder has oversized rear wheels for easy transport
and superior control on uneven surfaces. A flexible coupler
helps provide even grinding and maximum grinding disk life.
The unit's transport kickstand allows for easy starting, plus
protects the grinding disk and flexible coupler during transport
and storage. Rubber mount handle bars reduce vibration and
operator fatigue. It is available in two sizes: 11 h.p. and
13 h.p. The 13 h.p. model includes a convenient electric start.

Tribute to Bob Packard
the death of retired ACPA and PCA employee, Robert G. (Bob)
Packard, P.E., the Concrete Pavement Education Foundation
(CPEF) has proposed a scholarship in his name. The award is
among other planned awards, scholarships, and grants for students
and professionals in the concrete pavement industry.
proposed, the "Robert G. Packard Award," will be presented
to an undergraduate or graduate student for an outstanding
paper on concrete pavement design. For additional information,
please contact Robb
Jolly at 202-842-1010.
retired from ACPA in 2000 after more than 45 years of service
to the cement and concrete pavement industries. Many of technical
works, including those written early in his career, are either
still in use or have become the basis for other advanced technical
documents. He also was a two-time recipient of the distinguished
ACPA Hartmann-Hirschman award.
related news, a very fitting tribute to the late, world-class
engineer was written by John Hodgkinson of Sydney Australia.
He recalled: “The professional and personal hospitality and
his vast technical knowledge were of material significance
in transforming concrete highway development in Australia
from the late 1970’s.” The full tribute appears on the website

Important Parts of a Grinding Machine
grinding is done with specially designed equipment that uses gang-mounted
diamond saw blades to cut through bumps in the concrete surface.
The function of diamond grinding equipment is similar to that
of a common wood plane. The saw blades shave off the fault or
bump and the rear wheels follow behind in the smoothened path.
grinding equipment is also used to remove bumps from new pavements.
The equipment may be smaller for new pavement bump grinding, but
many of the same principles apply.
remove bumps and reprofile the surface effectively, the proper
equipment should be used. Figure
1 shows the basic components of a grinding machine. The three
most important aspects of a grinding machine are:
weight of the machine,
horsepower available to the grinding head, and
