The double roller compactor is essential for balancing compaction quality and structural safety in bridge deck projects. Using Mexico City’s elevated bridge project as an example, this case demonstrates how WALMACH’s double drum rollers deliver efficient, precise compaction under demanding conditions.
I. Country and Project Background
Country: Mexico
Project Background: Asphalt paving and renovation project for urban elevated bridge decks in Mexico City, with stringent requirements on equipment weight, vibration control, and mobility.
II. Client Background
The client company, founded in 1985, is renowned for its expertise in large-scale infrastructure construction, covering highways, dams, and complex urban structures. Its subsidiary specializes in bridge construction and rehabilitation, operating over 200 pieces of heavy equipment, with an engineering team that includes 15 certified bridge experts.
III. Client Requirements
- Lightweight and Low Vibration: Equipment must comply with strict bridge deck construction standards to prevent structural damage.
- Efficiency and Flexibility: Capable of rapid relocation and high-efficiency operation in busy urban traffic environments.
- Precision Compaction: Ensure the asphalt surface achieves high standards of smoothness and density.
IV. WALMACH Double Roller Compactor Solution
To address the specific conditions of bridge deck paving, WALMACH, a leading road roller manufacturer, provided a comprehensive roller solution, including the WD106HF 10 ton roller and the WD04 double drum vibrating roller.
- Precise Control: Both rollers feature lightweight designs that meet bridge deck load limits. Their hydraulic vibration systems offer adjustable frequency/amplitude for bridge-safe compaction. The WD04 double drum vibrating roller excels in detailed work like edges and joints.
- Superior Mobility: Compact builds and hydraulic drives deliver smooth speed control and tight steering, ensuring easy movement on narrow decks.
- Smart Operation: A microprocessor-controlled spray system prevents sticking while minimizing water use. The WD106HF 10 ton asphalt roller consistently produces high-quality surface finishes.
V. Overview of Cooperation
By showcasing successful application cases of WALMACH road rollers in China’s bridge construction projects and incorporating the actual working conditions of local road surfaces in Mexico, we tailored a technical solution for the client: the double drum rollers work in coordination to achieve rapid and precise supplementary compaction in bridge edges and special areas. Ultimately, with professional product performance and targeted solutions, WALMACH equipment earned the client’s recognition and selection.
VI. Client Feedback
“The WD106HF 10 ton roller and WD04 double drum vibrating roller combination provided by WALMACH is an ideal solution for bridge deck paving. They perfectly balance compaction effectiveness and structural safety. Their flexibility, reliability, and intelligent features have significantly improved our construction progress and quality in complex urban environments.”
