When the track consists of two straightaways of 100 meters each and the two curves of 100 meters each.
A permeable track surface allows surface water to pass through to the base asphalt. A non-permeable surface prevents surface water to pass through.
A double bend track has a compound radius curve (usually two small curves and large curve formed by three different radii forming one complex curve) at each end. This type of layout provides for a much wider playing field than an IAAF track.
A 494D or 495D longitudinal plastic grate.
Point of curve which is located where the straightaway transitions to the curve.
8 inline catch basins.
Yes, it’s the only way System 4000 channels can be used on the entire 400 meter track.
No, the System 2000 or System 3000 radius channels can be used in the curves.
The length of the straightaways. When the total of the two straightaways are subtracted from 400 meters you have determined the total number of meters in the curves.
HD can accommodate 4 layers (8ft) while SD can accommodate 3 layers (9ft).
The measurement from the inside of each painted lane line.
What is the distance from the inside edge of a painted lane line to the theoretical line of running?
System 4000 is available in sloping or non-sloping. What are the 3 non-sloping channel numbers/depths?
The three non-sloping channel numbers recommended are 4002, 2010 and 4020.
System 2000 & System 3000 are slot channels, what is the purpose of the “bridges” located in the slots?
To prevent the slot from closing or collapsing from pressure created by freeze thaw or by other means
EPDM rubber (ethylene propylene diene monomer rubber) is a type of synthetic rubber that is used for the ACO Sport safety edge on channels and elastic curbing.
Other than track and field installations, what is another popular use for System 7100 elastic curbing?
Edging or containment curbs for play areas.
Modular jump pits.
What are the names and system numbers for the 3 configurations for the System 7300 modular jump pits?
High School, NCAA, and IAAF
The 1980 Moscow which was due to the boycott by many countries.
System 2000, System 3000, System 4000 and elastic curbing.
