 About
the Port
The Port of Oakland was established in 1927, and is
a world-class international cargo transportation and
distribution hub. Located on the mainland shore of
San Francisco Bay, one of the great natural harbors
of the world, Oakland was among the first ports globally
to specialize in the intermodal container operations
which have revolutionized international trade and
created the global economy. Since 1962, the Port has
spent more than $1.4 billion to construct 1210 acres
of marine terminals, intermodal rail facility, and
maritime support area. This includes over $700 million
for the current Vision 2000 program, which includes
development of two new maritime terminals, a new intermodal
rail facility, deepening channels and berths from
-42' to -50', and a new public park and wildlife habitat.

The Port's Challenge
Ports across the globe have been struggling to find
a cost-effective solution for the pavement deformation
problems experienced from the use of heavy Rubber
Tired Gantry Cranes, Top-Pick Forklifts and other
heavy machinery. Rutting from this type of equipment
can sometimes reach 6” in as little as six months.
The Port of Oakland is no different. In some cases,
the Port was repairing their surfaces every few months,
as the rutting in some areas became too extreme to
operate their equipment in. Not only did the rutting
and dimpling cause decreased efficiencies for the
port’s operations, it posed huge safety concerns
for their employees. The Port of Oakland needed a
quick fix to this problem, and looked at some other
alternatives such as concrete and paving stones; but
both of these alternatives were too expensive and
didn’t provide the flexibility that the port
needed, as they frequently make layout changes.
The Solution
The Port of Oakland was able to solve their rutting
problems with the use of Resperion’s IntegraBase.
The Port of Oakland placed 30,000 tons of AR 8,000
hot mix in berths 57&59, part of the Port’s
$600 million Vision 2000 project. The Port created
a large test section for comparing the behavior of
the treated and untreated asphalts under the loads
imposed by RTG's, forklifts, grounded or stacked containers,
and containers on chassis. The Port constructed untreated
basecourses with depths of 7.5” and 10”.
IntegraBase basecourses were constructed at 5”
with a slurry seal.
Quote from Bernard
Wroblewski, P.E.
Civil Engineer – Port of Oakland
“IntegraBase was used in sub-areas of the Berths
57-59 terminal that have both rubber tired gantry
(RTG) crane activity and typical container handling
activity with top picks, side picks, and trucks. After
approximately 8 months of terminal operation, the
RTG runways with IntegraBase are experiencing little,
if any, rutting. A portion of these areas have a reduced
thickness asphalt section. The RTG runways without
IntegraBase are experiencing rutting depths in the
range of 3 1/2 to 4 inches.”
