**************************************************************************
NOTE: Before selecting a protective surfacing
system, evaluate the different types of protective
surfacing systems to determine the most appropriate
surfacing for the climate, accessibility, play
value, and cost. Consider life cycle maintenance
cost.
Synthetic Surfacing System: Synthetic surfacing
systems, either unified or combined, meet
accessibility requirements and have less daily
maintenance requirements than loose-fill surfacing
systems. Synthetic surfacing systems have limited
play value. These systems may be used to add color
patterns to the playground to be used for play
activities.
Loose Fill Surfacing System: The only loose fill
surfacing that meets accessibility is engineered
wood fiber. To maintain accessibility there needs
to be a commitment to replenishing the material
every month with the same engineered material. Some
loose-fill materials such as sand, not only provide
a good impact attenuation surface, but have
excellent play value. Loose fill surfacing systems
require daily maintenance to maintain impact
attenuation performance due to material
displacement, decomposition, and compression.
Depth of Material: Depth of the protective
surfacing is determined by both the fall height and
the type of protective surfacing system selected.
**************************************************************************
Materials shall be the standard products of a manufacturer regularly
engaged in the manufacture of protective surfacing and shall be similar to
surfacing in satisfactory use a minimum 5 year calendar period. Protective
surfacing consists of two systems; synthetic surfacing and loose fill
surfacing.
2.2
SYNTHETIC SURFACING
Synthetic surfacing includes the following: poured-in-place system; tile
system; and combination system. The synthetic surfacing consists of either
impact attenuating substrate covered by a wear surface bonded to produce a
unified system; a shredded rubber or aggregate substrate covered by a
polyethylene plastic woven sheet wear surface; or a uniform material
manufactured in such a way that the top portion meets the requirements
specified for wear surface.
2.2.1
Subbase
The subbase for synthetic surfacing may be either concrete, aggregate, or
bituminous material.
