This study was prepared on behalf of the City of San José (California) to explore the feasibility of using recycled pavements in the construction or resurfacing of trails. The report concludes that the use of recycled materials is both financially and environmentally feasible, and the use of recycled materials in trail construction is warranted. Three types of recycled material were evaluated: recycled base aggregate, rubberized asphalt, and recycled hot-mix asphalt.

Recycled base aggregate is a cost effective material that is readily available and may have performance advantages over virgin base aggregate.
Rubberized asphalt is more costly than conventional asphalt and current availability for small scale projects is limited, but it does have performance advantages.
Recycled hot-mix asphalt is also currently difficult to procure but may in time become a more readily available material. It is more costly and appears to perform similarly to conventional asphalt.

There are possible negative environmental impacts associated with these recycled materials, primarily with regard to water quality. Potential mitigation measures are suggested in this study.

Multi-use Trail Surfacing Options
by George Hudson, Principal, Alta Planning + Design

When approaching a trail project, trail designers and local agency representatives often assume their trail will be surfaced with asphalt or perhaps concrete if budget allows. These are some of the most common and acceptable materials used on trails. But this may not be what local residents had in mind when the trail idea was initially conceived. Or, local residents may not have considered the trail surface until a specific surface was proposed, and then suddenly everyone has an opinion. Trails typically serve a transportation function but most trail users do not want a trail to appear as a mini-roadway. This often leads designers into an exploration of possible trail surfacing options.

Center for Dirt and Gravel Road Studies

StephenMRTC — Thu, 10 Sep 2009 16:38:00 GMT

Created in 2001, the Center for Dirt and Gravel Road Studies at Penn State University is contracted by the PA State Conservation Commission (SCC) to provide services to PA's Dirt and Gravel Road Maintenance Program. The center’s efforts on this front include:

Development and delivery of Environmentally Sensitive Maintenance (ESM) training.
Technical documentation of ESM practices.
Educational efforts for conservation districts.
Technical assistance on projects.
Development and maintenance of a GIS System to track and map projects.
Advising the SCC on program policies.

Currently, approximately half of the Center's funding comes through Pennsylvania's Dirt and Gravel Road Maintenance Program. The Center also partners with other agencies through grants to provide technical assistance and research including the PA Bureau of Forestry, the Chesapeake Bay Commission, the PA Department of Environmental Protection, the Susquehanna River Basin Commission, the Great Lakes Commission, and others.
