IntegraBase sections experienced little to no rutting compared to 4″ in untreated sections

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 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.


“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.”
