to give players a three-step warning (at full speed) that they are
approaching a barrier. Their first step onto the track alerts them with
a different texture under their feet. Their second and third steps allow
players to decelerate before making contact with the barrier. The width
of the warning track is determined by the oldest age group using the
field.
For recreational fields, rely on surface grade and positive surface
drainage to move water off the track. A 0.5% to 1% slope will carry
the water away from the field. For professional and collegiate fields,
stronger tracks should be built that incorporate both subsurface and
surface drainage features to quickly remove water.

Type of material and gradation.
This is usually a ground aggregate of some kind. Recreational field
warning track material should use 3/16" minus gradation. Professional
or collegiate facilities will use a slightly finer 1/8" minus gradation.
■ APPROXIMATE COVERAGE of DuraTrax Warning Track Mix
■
Depth of material.
Area 1 ton of DuraTrax will cover...
A minimum of 3" is enough for most recreational fields if only mowers
and turf utility vehicles will be using the track. If vehicles over 2 tons
will be using the warning track, it is strongly advised to have a 3" to
4" stone road base installed below the 3" of warning track material —
especially for collegiate and professional baseball and softball facilities.
