Slurry Seal Machine & Micro Surfacing Machine
Micro surfacing machine is designed for both conventional slurry seal materials and modified emulsified asphalt slurry used in micro surfacing applications. The micro surfacing machine integrates material storage, precise metering, continuous mixing, and spreader box application into one road maintenance system.
The slurry seal machine is mainly used for micro surfacing and underseal construction on high-grade highways, as well as slurry seal and micro surfacing work on secondary roads, tertiary roads, and municipal roads. By controlling the flow of emulsion, water, aggregate, filler, and additives, the micro surfacing paver helps contractors produce a consistent mixture and apply it evenly across the pavement surface.

Features
Efficient Mixing and Anti-Leakage Design
- Rear remote speed control
The rear-platform operator can adjust the vehicle speed according to the mixture condition in the spreader box, reducing communication errors between the operator and the driver during noisy jobsite operation and supporting more consistent paving quality - Corrosion-resistant emulsion and water tanks
The emulsion tank and water tank are treated with corrosion-resistant composite materials to reduce corrosion caused by water and asphalt emulsion, helping extend tank service life - Double-layer aggregate hopper baffles
The aggregate hopper uses a double-layer baffle structure to help prevent material leakage and maintain cleaner, more stable paving performance - Twin-shaft pugmill with easy-clean design
The twin-shaft mixing chamber is designed to reduce dead corners, helping produce a uniform slurry mixture while making post-operation cleaning easier - Centralized rear-platform control
The control system uses a human-machine interface, allowing the operator to complete key operations from the rear platform for easier monitoring and adjustment during paving - Full digital metering system
Flowmeters display the usage of asphalt emulsion, water, and additives in real time, helping operators control material proportioning more accurately - Fully hydraulic drive
Each working system is independently hydraulically controlled, reducing power interference between systems and supporting smooth, stable operation
- Comfortable chassis configuration
The chassis is equipped with power windows, remote door lock, air conditioning, sleeper, and ABS to improve driving comfort and operating convenience - Folding aluminum alloy ladder
The folding ladder provides convenient access to the working platform while keeping the overall structure practical and compact - Aluminum roller shutter doors
The roller shutter doors can be opened during construction without blocking the driver’s view or interfering with traffic on either side of the vehicle - Optional fiber additive system
A fiber additive system can be configured for projects that require fiber-reinforced slurry seal or micro surfacing applications
