Asphalt rubber is the largest single market for ground rubber in the United States, consuming an estimated 220,000,000 pounds ...

[20] While a potential use for tires that would otherwise fill landfills and present a fire hazard, rubberized asphalt has shown greater incidence of wear in freeze-thaw cycles in temperate zones because of the non-homogeneous ...
This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.

The proper length of the first lane of a competitive running track is 400 m (1,312.3 ft). Some tracks are not built to this specification, instead being a legacy to imperial distances such as 440 yd (402.336 m), equivalent to a quarter of a mile.
If the template has a separate documentation page (usually called "Template:template name/doc"), add [[Category:Arena Football League templates]] to the <includeonly> section at the bottom of that page.
