Slurry Seal & Micro Surfacing Trailer
Micro surfacing trailer can mix and apply conventional slurry seal materials and modified asphalt emulsion slurry for micro surfacing. It is designed for micro surfacing and underseal work on highways and major roads, as well as slurry seal, micro surfacing, and underseal applications on secondary roads, local roads, and municipal streets.
As a trailer-mounted solution, the micro surfacing trailer is positioned as a mid- to high-end model in the slurry seal machine category. For markets where the supplied truck chassis may not meet local registration requirements, the Micro Surfacing Trailer is supplied without a chassis, allowing customers to pair it with a locally registered chassis or towing vehicle.

- Corrosion-resistant emulsion and water tanks
The asphalt emulsion tank and water tank are treated with corrosion-resistant composite materials, helping reduce corrosion from water and asphalt emulsion and extending service life. - Fully hydraulic drive
Each working system is independently hydraulically controlled, reducing power fluctuations between systems and supporting smooth, stable operation during slurry seal and micro surfacing work. - Dead-zone-free twin-shaft pugmill
The twin-shaft mixing chamber helps ensure uniform slurry mixing while making post-operation cleaning easier. - Reliable component configuration
Key components are selected from recognized international brands to support stable performance, reliable operation, and longer service life. - German Bürkert metering system
The metering system improves material proportioning accuracy and stability, helping maintain consistent mixture quality during construction.
Cummins Auxiliary Engine
The Cummins auxiliary engine provides independent power for the Micro Surfacing Trailer, supporting stable operation of the hydraulic drive and working systems.
Control System
The Siemens PLC control system displays the flow rates of water, asphalt emulsion, and additives on the LCD screen at the same time. Operators can adjust material output according to actual jobsite conditions, helping maintain stable mixture proportioning during construction.
Belt Conveyor Discharge
The belt conveyor discharge outlet uses double-layer aggregate sealing strips to help prevent aggregate spillage, reduce pavement contamination, and protect paving quality.
1 m Slurry Spreader Box
The 1 m slurry spreader box is suitable for narrow-width slurry seal and micro surfacing applications.
2.4–4.2 m Slurry Spreader Box
The 2.4–4.2 m slurry spreader box supports wider road maintenance applications. The adjustable working width helps the Micro Surfacing Trailer adapt to different road widths and project requirements.
