Product Overview
The document discusses the ROBO®STATIFLEX reinforcing joint beam, an optional extra for expansion joints, designed to enhance durability, comfort, and noise reduction. It is made from ROBO®FLEX polymer concrete, known for its high resistance to deformation and elasticity.

Principle and Benefits
The reinforcing beam prevents track groove formation near expansion joints, ensuring a smooth road surface. It can be driven on after just 6 hours, significantly reducing construction time, especially during renovations. Key benefits include increased service life of expansion joints, improved driving comfort, and reduced noise.

Design Characteristics

• Connects bridge sealing and surface layer.
• Prevents track grooves, extending joint service life.
• Enhances road user comfort and reduces noise.
• Short installation time, suitable for new and existing joints.

Properties
The ROBO®STATIFLEX beam offers sufficient load-bearing capacity for vertical and shearing forces from traffic. Its installation aligns the road surface with the steel profile, reducing noise and increasing comfort. The prevention of track grooves eliminates impacts on joints, extending their durability and reducing maintenance costs.

Installation Process
ROBO®FLEX polymer concrete is mixed and molded into prepared recesses, filling all cavities without additional compression. It cures quickly, allowing traffic to resume after 4 to 6 hours.

Technical Data

• Compression strength at 20 °C: min. 16 N/mm²
• Elastic modulus (pressure): min. 170 N/mm²
• Adhesive tensile strength to sandblasted steel: min. 3.0 N/mm²
• Adhesive tensile strength to concrete: min. 1.5 N/mm²
• Pot life: approx. 10 minutes

Expansion Joint Types
The document also lists various mageba expansion joint types, including single gap joints, sliding finger joints, cantilever finger joints, and modular expansion joints.
