General
Description
SpectraTrack
EPDM is a one layer, insitu, spike resistant, pervious, resilient,
polyurethane athletic surface. The recommended thickness is 12-13mm
(1/2"). The layer consists of colored EPDM granules bound together
with a specially formulated, single component polyurethane binder.
Recommended
Method of Installation
Asphalt
Check
The asphalt must be impervious and the finished level must not vary
more than +/- 4mm when measured with a 3 meter long straight edge. High
areas shall be milled off or ground off or heated and scraped to reach
the required level. Low spots shall be cleaned, primed and leveled with
Conipur 210 A/B mix to obtain the required level.
Installation
of SpectraTrack EPDM
Ensure that the asphalt base is clean and dry. Remove any mud, debris
or foreign matter by sweeping, scraping or blowing.
Application
of Primer
Using an airless spray machine, spray on Conipur 74 evenly at the rate
of 0.15 kh/sqm (0.3 lb/sq.yd.). Allow the solvent to evaporate before
applying the base layer.
Mixing
of Conipur 322 and EPDM Granules
Conipur 322 and 1-4mm clean, dry EPDM granules are mixed in a force
mixer** at a recommended ration of 100 parts EPDM granules to 20 parts
Conipur 322 by weight.
Application
of the Base Layer
The mixed material is applied to the asphalt base at a thickness of
approximately 12-13mm (1/2") using a specially designed paver which
utilizes a heated screed to level and compact resilient layer. The base
layer is then allowed to cure (harden). The curing process depends on
temperature and humidity and normally occurs within 24 hours.
*Other
Conica recommended products can be used in place of those mentioned.
**In place of batch mixing a specially designed continuous mixer can
be used.
Line
Marking / Event Marking
The track shall be surveyed by an accredited surveyor and all lane and
event markings shall be according to I.A.A.F. guidelines.
Line
/ Event Spraying
Lanes and events shall be sprayed using a specially formulated two part
polyurethane paint, to I.A.A.F. recommendations and a certificate issued.
