The Dragon Patcher from Sweden Is an Innovative and Efficient Solution for the Quick Repair of Road Potholes, Reducing Costs and Increasing Worker Safety.
The Dragon Patcher is an innovative machine developed in Sweden that transforms the pothole repair process, providing faster, safer, and more economical solutions.
Its peculiar name comes from the nozzle that emits flames, resembling a dragon’s breath.
How the Dragon Patcher Works
The operation of the Dragon Patcher is conducted by a single operator from the vehicle’s cabin, eliminating the need for workers exposed to traffic, significantly enhancing safety. The repair process is carried out in sequential steps:
-
A traditional SC supermarket will be demolished to make way for a new R$30 million unit in Porto Belo, featuring 4,400 sq m, 140 parking spaces, and a promise to accelerate the chain’s expansion on the Santa Catarina coast.
-
China sends to Brazil a “tatuzão” of 2,600 tons and 133 meters to open tunnels up to Guarulhos and put São Paulo before the largest subway machine ever used in Latin America.
-
Chile accelerates a billion-dollar pivot: 38 energy storage systems are already under construction, totaling 4.6 GW, representing US$ 4.1 billion, and could enable the country to meet by 2027 the goal that seemed distant for 2050.
-
A kilometer-long bridge for cars in Brazil eliminates ferries and tolls, becoming the 3rd largest in Brazil with 1,244 meters, a 320 m central span without pillars, an investment of R$ 400 million, and construction completed in less than 3 years.
Area Cleaning: The surface of the pothole is cleaned with compressed air, removing debris and dirt.
Heating (if necessary): In cold weather conditions, a flame is used to defrost and dry the area, ensuring proper material adhesion.
Hot Bituminous Emulsion Application: A layer of heated bituminous emulsion is applied over the prepared area.
Aggregate Covering: A mixture of stones is spread over the emulsion, forming a strong and durable surface.
Traffic Ready: After application, the road is ready for traffic almost immediately, minimizing disruptions.
This method not only repairs existing potholes but also addresses smaller cracks that could evolve into potholes, preventing future damage.

Advantages of the Dragon Patcher
Speed: The Dragon Patcher can repair up to 150 potholes per day, with each repair taking about three minutes, which is significantly faster than traditional methods.
Economic Efficiency: Studies indicate that the cost per square meter of repair with the Dragon Patcher is considerably lower compared to conventional methods.
Enhanced Safety: The operation conducted from the cabin reduces workers’ exposure to traffic, increasing safety on site.
Sustainability: The use of biodiesel (HVO) as fuel helps reduce carbon emissions, making the process more eco-friendly.
Since its introduction, the Dragon Patcher has been used in various regions, including the United Kingdom, where it has shown effectiveness in maintaining rural and urban roads.
Its mobility and efficiency have been particularly valuable in areas with heavy traffic and adverse weather conditions.
The adoption of the Dragon Patcher represents a significant advancement in road maintenance technology, aligning with global trends of innovation and sustainability in infrastructure.
