Parking Stops
Commonly found in parking lots, parking stops are used to mark spaces and keep vehicles from rolling beyond a designated parking area. EPA's designation specifically covers parking stops made from concrete or containing recovered plastic or rubber.

Recommended Recovered Materials Content Ranges:
EPA's RMAN recommends recycled-content levels for purchasing parking stops as shown in the table below.
Material | Postconsumer Content (%) | Total Recovered Materials Content (%) |
---|---|---|
Plastic and/or Rubber 2 | 100 | -- |
Concrete Containing Coal Fly Ash | -- | 20-40 3 |
Concrete Containing Ground Granulated Blast Furnace Slag (GGBF) | -- | 25-70 |
1Transportation products containing recovered materials must conform to the Manual on Uniform Highway Traffic Control Devices used by the Federal Highway Administration, as well as other applicable federal requirements and specifications.
2Parking stops made with recovered plastics may also include other recovered materials such as sawdust, wood, or fiberglass. The percentage of these materials contained in the product would also count toward the recovered materials content level of the parking stops.
3Generally, 20 to 30 percent, but could be up to 40 percent. Fifteen percent when used as a partial cement replacement as an admixture in concrete.
Product Specifications:
American Society for Testing and Materials (ASTM) specification C595M-95 Standard Specification for Blended Hydraulic Cements specifies the appropriate mix design, including recovered materials content, for concrete containing coal fly ash and GGBF slag.

GSA Advantage!
Parking stops can be ordered through the General
Services Administration's (GSA's)
New Item Introductory Schedule. In addition, GSA
publishes various supply catalogues, guides, and schedules
for recycled-content products available through the Federal
Supply Service.
