Recently, the retrofitting service and technical team of D&G Machinery carried out a proactive customer follow-up visit in China. Focusing on the actual operation of D&G Machinery warm-mix bitumen foaming devices, the team visited four sites and followed up on 11 sets of equipment. During the asphalt mixing plant on-site visits, the team communicated with production supervisors, operators and field construction staffs to learn about equipment operation, warm-mix performance, and challenges customers encountered in application.

Follow-up results show that customers with continuous use of D&G Machinery warm-mix bitumen foaming device speak highly of the warm-mix performance. Those with intermittent or suspended use are mostly affected by site conditions and limited knowledge of warm-mix processes. D&G Machinery team gave customized on-site recommendations and will keep following up to help customers unlock higher value from their equipment.

Active User: Tangible Results, Trusted Reputation

In Hebei Province, the customer operates two asphalt mixing plants of well-known peer brands at one site, both of which are equipped with D&G Machinery warm-mix bitumen foaming devices, boasting excellent performance. According to the customer, the warm-mix process brings notable improvements in long-distance material transportation, low-temperature paving and the visual quality of asphalt mixture. What impressed the customer most is that D&G Machinery took the initiative to follow up with minor retrofit customers. This responsible and service-oriented mindset has won their full recognition. The customer commented: “We didn’t expect D&G Machinery to specially follow up on retrofit projects like ours. Your service awareness is truly outstanding.”

In Beijing, a well-known brand asphalt mixing plant has long been equipped with the D&G Machinery warm-mix bitumen foaming device, delivering excellent performance. On-site feedback shows that the warm-mix process features distinct superiorities when producing reclaimed asphalt materials, forming an optimal technical match. Since reclaimed asphalt production imposes high requirements on process precision, the warm-mix technology can improve workability, cut flue gas emissions, and improve asphalt mixture appearance. It also adapts well to long-distance transport and low-temperature paving.

Inactive User: No Performance Flaws — It’s All About Unlocking Full Application Synergy

The follow-up visits also revealed that some customers have installed D&G warm-mix bitumen foaming devices but use them infrequently. Discussions indicate this is related to specific working conditions, production processes and the organization of reclaimed asphalt production. The warm-mix technology is well compatible with reclaimed asphalt production. It achieves foaming by injecting a small amount of cold water into hot bitumen through the dedicated foaming unit, facilitating the integration of new and aged bitumen.

At present, certain projects still have room to refine the continuous operation and process, and the full potential of the equipment has not yet been realized. Advancing this new process requires readiness on the production side, as well as collaborative mechanisms developed gradually under real working conditions. This will help shift application status from “installed” to “regular and effective operation”.

DG Reach Service: Proactive Follow-up, Continuous Support, Commitment to Customers

This round of site visits proves that D&G Machinery warm-mix bitumen foaming device maintains outstanding cross-brand compatibility with various asphalt mixing plants. We provide proactive and sustained service for all retrofitting projects.

For active users, D&G Machinery service team helps summarize operational experience and further refine the warm-mix process. For non-users or users facing operational challenges, the team provides support covering process briefing, operation training, parameter tuning and system adaptation, closing the final gap between “plant installation” to “efficient plant operation”.

Going forward, D&G Machinery will remain customer-oriented, keep conducting on-site follow-ups and delivering ongoing support. Together with our customers, we will promote wider and reliable application of warm-mix bitumen foaming technology, powering more green and low-carbon road projects around the world.
