D&G Machinery Warm-Mix Bitumen Foaming Equipment Successfully Put into Operation in Guangxi
Recently, D&G Machinery successfully completed the commissioning of one warm-mix asphalt foaming equipment in Guangxi, China. This project involves the upgrading and retrofitting of a 3000-model asphalt mixing plant for a renowned domestic brand, standing out as a big breakthrough for D&G Machinery’s advanced warm-mix technology in the South China market. This collaboration not only demonstrates D&G Machinery's technical strength in the field of asphalt mixing plant, but also provides an innovative, eco-friendly, and efficient solution for road construction in Guangxi.
New Breakthrough in Warm-Mix Technology: Key Highlights of D&G Machinery
D&G Machinery’s warm-mix bitumen foaming equipment employs advanced warm-mix technology. With precise variable frequency control, it enables the mixing temperature of the warm-mix to be reduced by over 20°C compared to hot-mix of the same type, under conditions where their performance and application environments remain consistent. This technological breakthrough brings many benefits:
Significant Energy Saving & Emission Reduction
The lower temperature directly reduces fuel consumption and greenhouse gas emissions. According to calculations from multiple practical projects, it can save approx. 20%-30% of energy consumption per ton of mixture and reduce greenhouse gas emissions, such as carbon dioxide, by about 50%.
Improved Construction Environment
It significantly reduces the emission of asphalt fumes, cutting the discharge of toxic gases like asphalt smoke by over 80%, greatly improving the construction working environment and minimizing the impact on surrounding communities. This makes it particularly suitable for construction in city centers, residential areas, and environmentally sensitive zones.
Superior Material Performance
While lowering temperatures, D&G Machinery's warm-mix technology ensures excellent coating and adhesion between bitumen and aggregates through proprietary processes, maintaining performance and durability comparable to traditional hot-mix.
Extended Construction Window
The warm-mix process significantly enhances the fluidity of asphalt mixtures, greatly improving their workability. It prevents material embrittlement caused by low temperatures, extends the effective compaction time, enables construction to proceed under lower ambient temperatures, and broadens the construction window during cold seasons.
Proven Performance Across Multiple Regions: Excellence of D&G Machinery Warm-Mix Equipment
D&G Machinery’s warm-mix technology has been successfully adopted in many key projects across China, demonstrating outstanding adaptability and reliability:
Highway Project in North China
In a highway expansion project with D&G Machinery's warm-mix technology, it completed night-time construction without interrupting traffic, reducing energy consumption and asphalt fume emissions, earning high praise from local environmental authorities.
Urban Expressway Renovation in East China
In a densely populated urban center road renovation, the adoption of D&G Machinery's warm-mix technology for on-site construction resulted in a dramatic reduction in fumes at the paving site, with a 90% decrease in complaints from surrounding residents. This technology also helped extend the construction period, bringing significant social and economic benefits.
High-Altitude Project in Northwest China
In high-altitude plateau regions, D&G Machinery's warm-mix technology has completely resolved the problem of insufficient combustion in traditional equipment and uneven aggregate coating with blotchy mixtures under high-altitude and low-oxygen conditions. It ensures the stable quality of asphalt mixtures, filling the technological gap in construction within such challenging environments in the region.
Rooted in Guangxi, Radiating Across South China: A New Driving Force for Regional Development
As a frontier for China-ASEAN cooperation and a key place in the Western Land-Sea Corridor, Guangxi is experiencing rapid infrastructure development. The introduction of D&G Machinery's warm-mix bitumen foaming device provides a more eco-friendly and efficient technological option for road construction in Guangxi and across South China. The installed equipment can be customized to suit the special climatic conditions and material characteristics of Guangxi, meeting construction requirements in rainy and humid environments. Additionally, the equipment is compatible with multiple warm-mix technology routes, allowing for flexible selection based on specific project requirements to provide optimal solutions for customers.
D&G Machinery will continue to invest in R&D to further upgrade warm-mix technology and explore deeper integration with Reclaimed Asphalt Pavement (RAP) technology, promoting the application of higher proportions of plant hot recycling under warm-mix conditions. Meanwhile, we are committed to integrating smart technologies such as the Internet of Things (IoT) and big data analytics into equipment systems to achieve precise production control and predictive maintenance, creating more values for customers.
In the future, D&G Machinery will continue to empower customers with innovative technologies, and forge ahead steadfastly on the path of sustainable development, contributing more green solutions to road construction in China and around the world.
