A New Generation
The Velodrome at Stone Mountain Park, the Cycling Venue for the 1996
was the first in a new generation of high-performance bike
tracks. Designed from the ground up with superior techniques and
materials, this track represented a design breakthrough that sets a
new standard against which all future tracks will be judged. This
ground-breaking design approach provides world class performance at a
dramatic cost savings over traditional velodrome fabrication methods.
- Measure Line Length: 250.00 m
- Raceway Width: 7.2 meters
- Max Banking: 42 degrees
- Min Banking: 13 Degrees
- Outside Dimensions: 115 x 55 meters
- Infield Dimensions: 100 x 40 meters
75 Tons of Steel
The track is constructed with 75 tons of rectangular and square steel tubing
that is cut and welded into sections using special jigs. The resulting
weldments are coated and then shipped to the site for final assembly.
236 Unique Sections
The track is of modular design, comprising 236 unique,
offsite-fabricated sections that rigidly bolt together. No sections are
flat, and no two sections are alike, yet the sections are precisely
calculated and fabricated to such tight tolerances that they join to
form a smooth, continuous curved surface.
Although suitable for permanent installation, the modular design of the
velodrome allows us to produce a structure possessing all the important
qualities of a permanent track, yet capable of damage-free disassembly
and relocation. All pieces of the track easily fit in standard
containers for legal transportation anywhere without special permits.
Textured Polyester-Wood Laminate Surface
The 236 steel sections are surfaced with a extra-thick (11-ply)
polyester/wood laminate panel. The surface material is manufactured
from sustainably reforested wood and combines several desirable
- Moisture and Heat Resistance
- UV Resistance
- Traditional board track appearance.
- Long Range Smoothness
- Optimum Surface texture
Steel and Transparent Plastic Safety Fence
Mounted on the outer edge of the velodrome is a sturdy safety fence.
The fence is made of formed-steel and shatterproof, high-strength,
transparent plastic. Unlike fences made other, weaker materials, this
fence acts as a highly effective safety barrier, while only minimally
obstructing the view of the racing.
New and Exclusive Design Concepts
This velodrome provides all standard features and markings required for
international competition. Although adherence to important traditional
track design concepts was maintained, new approaches and techniques were
developed to push the velodrome design art to new heights.
The track is designed using a hybrid Symbolic/Numerical computer model
implemented in the flexible and powerful high-level symbolic math
allows simultaneous and rapid optimization of various curve and banking
parameters under a complicated set of constraints. In particular, the
shape of the surface has several important features, which are
automatically maintained by the Mathematica design software
- Zero-bubble pole line
- Optimized Asymmetrical Superelevation
- Cornu Spiral Transitions
- Twisted, Radius-Cupped Panel Segments
3D CAD Model
The Symbolic/Numerical model in Mathematica produces a 3D numerical
description of every part in the entire velodrome. This output is fed
directly into CAD software to produce a 3D
rendering. Once in the CAD system, the design can be manually
reviewed and checked. It should be emphasized that no layout or other
manual design operations are performed in the CAD system. This virtually
eliminates the chance of design error. The CAD system is used solely to
generate fabrication drawings for the individual parts.
The totally automated design process allows an extremely complex shape
to be precisely designed and fabricated at low cost, and on a quick,
no-rework schedule with 100% certainty of success.
Post-Assembly Alignment and Optimization
Imperfections caused by material tolerances and non-uniformities in the
foundation are corrected using various proprietary design features that
allow the surface to be aligned at the site. Ultra accurate laser
surveys and computer analysis are used as an essential part of this
Stone Mountain was number one. Here's our tenth track, being erected in Qatar
