The entire unit is mounted on a mobile trailer chassis, eliminating the need for a concrete foundation. It can be freely towed and quickly relocated, offering exceptional mobility.​
Standard models include 20TPH, 40TPH, 60TPH, 80TPH, 100TPH, and 120TPH, capable of meeting the production requirements of large, medium, and small-scale road construction projects. The entire series is equipped with an intelligent batching system, an automatic temperature control system, and a sealed dust collection system, enabling precise control of aggregate proportions and asphalt usage. The hot-mix asphalt produced fully complies with domestic and international road construction quality standards. Thanks to advantages such as modular integrated design, a small footprint, and intelligent control, the equipment perfectly balances production efficiency with flexible construction requirements.

Why Do Construction Contractors Prefer Mobile Asphalt Production Equipment?

Today’s road construction projects are typically characterized by dispersed work sites, tight schedules, and frequent site changes. Traditional fixed mixing plants involve high initial setup costs, cannot be relocated flexibly, and offer extremely poor adaptability. In contrast, mobile drum asphalt mixing plants have become the preferred choice for construction projects due to their multiple core advantages.
1. Significantly reduces overall project costs: Traditional construction methods require transporting finished asphalt over long distances from fixed mixing plants, resulting in high transportation costs. Furthermore, long-distance transport causes the asphalt to cool and degrade, affecting paving quality. Mobile mixing plants enable on-site production and paving, eliminating the need for long-distance transport and directly reducing transportation costs by more than 30%, while also preventing material waste and asphalt quality degradation.
2. Improved Overall Construction Efficiency: The equipment requires no complex foundation work and can be assembled, commissioned, and put into operation within hours of arrival, significantly shortening the project preparation cycle. For short-term projects such as rural road construction and short-term pavement repairs, this completely resolves issues related to slow equipment deployment and project delays.
3. High Adaptability and Reusability: A single unit can serve multiple dispersed job sites and be repeatedly relocated for use, significantly improving equipment utilization and return on investment. Combined with an intelligent automated control system, it reduces human operational errors, lowers labor costs, and ensures consistent asphalt production quality.

How Does the Mobile Design Solve Challenges in Remote Projects and Emergency Road Repairs?

The construction of mountain roads, the renovation of island roads, and emergency road repairs in urban areas have long been major challenges in road construction. Remote sites are far from fixed asphalt mixing plants, making material transportation difficult and costly; emergency repair projects have tight deadlines that do not allow time for setting up fixed equipment. Mobile drum asphalt mixing plants precisely address these industry pain points.
For remote sites with limited transportation access, the equipment features a trailer-mounted design that can be towed by standard construction vehicles, making it suitable for complex road conditions such as mountain roads and dirt roads. With a compact footprint, it can operate normally even in confined spaces, completely eliminating the geographical constraints of fixed mixing plants and enabling the production of high-quality hot asphalt anytime, anywhere.
For emergency scenarios such as urban pavement damage, highway pothole repairs, and post-disaster road reconstruction, the equipment can be rapidly transported to the construction site and put into operation within a short time, enabling simultaneous asphalt production and paving. This effectively shortens road closure times, minimizes traffic disruption, and resolves the challenges of slow progress and low efficiency associated with traditional emergency road repairs.
