Reconstructed Hudson Bay Company Fort

Visually Appropriate Accessible Pavement for Historical Sites

®

The National Park Service has improved accessibility by installing multi-purpose all-

weather pavements at the reconstructed Hudson Bay Company post at the Fort Vancouver National Historic Site in Vancouver, Washington. Starting in 2002 with their first installation of the NaturalPAVE XL Resin Pavement surfacing for walkways surrounding the reconstructed buildings within the fort, the pavement system has since been expanded throughout the fort and exterior gardens out to the city street, the visitor parking lots and to the site of the historical Kanaka workers village outside the fort. The NaturalPAVE XL Resin Pavement mix selected for the project is formulated with aggregate materials of earthy brown coloration to provide the look of dirt paths historically present when Hudson Bay Company employees of the 1830s and 1840s occupied the site. To visually blend the installations from the various paving phases inside and outside the fort, and to present a roughened and even more historically appropriate appearance, the same NaturalPAVE XL Resin Pavement mix was reformulated as a slurry seal and applied with squeegees and brooms once all the paving phases were completed.

The pavements for the adjacent Vancouver Land Bridge project were constructed with the same NaturalPAVE XL Resin Pavement mix, furnishing a visual continuity for both of these related projects. The Land Bridge is an artful pedestrian overpass traversing State Route 14 and reconnecting the historic fort, via a paved trail system, with a park on the Columbia River waterfront where a wharf once stood at the time when this was the busiest port on the West Coast. The Vancouver Land Bridge also serves as a link in the regional Discovery Trail System commemorating the history of the Lewis and Clark Expedition. The system is part of the Confluence Project under the direction of artist and designer Maya Lin. The Vancouver Land Bridge segment was a joint effort of the Confluence Project, the City of Vancouver, the Washington State Department of Transportation and the National Park Service.

In response to a request from National Park Service engineering staff in 1989 to develop a more aesthetic and an environmentally friendly alternative to hot mix asphalt pavement for access to natural areas and historic sites, Soil Stabilization Products Company, Inc. (SSPCo) took on the challenge. Today, cold-applied NaturalPAVE XL Resin Pavement is placed by standard asphalt paving equipment for street, road, driveway and parking lot applications as well as for National Park Service accessibility requirements. The pavement installations at Fort Vancouver National Historic Site and Vancouver Land Bridge are testimonial to the initiative of the National Park Service and SSPCo, setting a standard for green construction technology and

natural aesthetics. Designers can now specify NaturalPAVE XL Resin Pavement mixtures for their projects based upon a variety of reasons, including environmentally friendly composition and construction process, natural aesthetic, historically appropriate appearance, thermal resistance and solar reflectivity to combat Urban Heat Island effect and its beauty as an architectural feature complementing the landscape or built structures. NaturalPAVE XL Resin Pavement mixtures are also typically stronger and more flexible than standard hot mix asphalt pavement mixtures, so designers can know they are upgrading their projects in regards to pavement quality as well as aesthetic and environmental quality concerns.

NaturalPAVE XL® Resin Pavement™, similar to hot mix asphalt, is a surface course pavement material that is reliant on the workmanship of the pavement contractor during placement operations and on the strength and stability of the base course and underlying layers upon which it is constructed. SSPCo is a supplier of pavement materials only and not a contractor, engineer, installer, or construction inspector.
