Bike Path - Pathway

• Aims to enhance
• Durability
• Environmental Aspect
• Aesthetics
• Alternatives Investigated
• SBR (Styrene-Butadiene)
• EPO-KEM RUBA-TEX

6
Bike Path - Pathway

• SBR
• Made from recycled car tires
• Good durability
• Performs well in temperature range 45C - 100C
• Construction
• Tile format
• Construction surface must be weather tight

Bike Path - Pathway

• EPO-KEM RUBA-TEX
• Composition of polyurethane resins, accelerators,
  adhesion promoters and coloured rubber granules
• Durability
• Same Shore Hardness value as SBR
• Three times Tensile Strength
• Temperature Range from 20C - 80C
• Better Weather-ability and UV resistance
