WALMACH provided a solution for the Municipal Engineering Bureau in in the capital of Saudi Arabia, where temperatures exceed 45°C. Their WD126HF (12-ton) and WD148HF (14-ton) double drum asphalt rollers featured anti-stick technology and enhanced thermal management, ensuring superior compaction quality and reducing maintenance costs by 30%. The client highly praised their performance and reliability.
I. Project Background
Asphalt paving and annual maintenance of municipal roads in the capital city of Riyadh. Summer temperatures frequently exceed 45°C, placing extremely high demands on asphalt paving and compaction techniques.
II. Client Background
The client is Al-Riyadh Infrastructure Company, a premier Grade-AAA certified contractor specializing in municipal roadworks under long-term contract with Riyadh’s Municipal Engineering Bureau.
Having operated in Saudi Arabia’s construction sector since 1998, company maintains a fleet of 287 specialized compaction and paving units. While historically dependent on German compaction equipment for their most demanding projects, it was actively seeking technologically advanced partners who could provide superior high-temperature performance.
III. Client Requirements
The client required 12–14 ton road compaction equipment units for the final compaction of asphalt surface layers to ensure high smoothness and density standards. The equipment also needed efficient water spray and anti-stick systems to adapt to high-temperature construction environments exceeding 45°C. Additionally, a mini road roller was required for precise construction in confined areas such as sidewalks and road shoulders.
IV. WALMACH Road Roller Solution
To address Saudi Arabia’s high-temperature municipal requirements, WALMACH supplied the WD126HF (12-ton) and WD148HF (14-ton) fully hydraulic double roller compactor units, supplemented with the WD04 (4-ton) small road roller. The customized design included:
*A high-temperature kit with large-capacity anti-evaporation spraying and patented scrapers to prevent asphalt adhesion
*Enhanced thermal management for stable hydraulic performance in extreme heat
*Low-noise engineering meeting urban environmental standards
V. Cooperation Overview – WALMACH Double Drum Asphalt Roller
The client previously used rollers from an international brand. Comparative tests showed WALMACH’s three key advantages:
Superior heat management eliminated overheating alarms at 45°C; the anti-stick system delivered better compaction quality; and local parts support cut maintenance costs by 30%. These advantages made WALMACH the new choice for municipal road maintenance.
V. Client Feedback
“The WALMACH double drum roller series fully meets our municipal maintenance needs. We are particularly impressed by its excellent anti-stick performance and compaction smoothness. The small road roller has also significantly improved efficiency in confined areas. WALMACH is a reliable partner and road roller manufacturer for us.”
