How to Install a Running Track

Synthetic rubber tracks are easier on runner's shins and ankles.

Proper installation of a synthetic rubber track requires many steps in order for it to last long and support runners properly.

Site Preparation

Fine-grain gravel may be used as a foundation for the track.

To prepare the site for installation, it is recommended that you pave at least 2 inches of asphalt over the area or on top of a compacted gravel foundation. Let the asphalt sit for about two weeks, allowing it to cure.

Beginning Construction

Coat the surface of the asphalt with "tack coat," a tacky binder that helps to adhere the first layer of rubber to the asphalt. Rubberized granules, strands of rubber, or recycled EPDM (ethylene propylene diene monomer) rubber, are mixed with binder and spread out over the tack coat. Allow the first layer to dry for approximately six hours to one day.

Further Installation

Apply subsequent layers of rubber until the desired thickness is achieved, usually requiring 3/8 to 1/2 of an inch. There are typically about five layers for granule rubber particles and seven layers for strand rubber.

Tips

Take note of the weather during construction. If it is raining or threatening to rain, it is advised that construction be postponed, since the latex might be washed away before it has time to dry completely.

Black rubber surfaces are usually upgraded to a red structural spray surface, as the black surface is more prone to structural damage due to excessive heat.
