Sinotruk HOWO 4x2 Synchronous Chip Sealer with PLC Control and Large Insulated Asphalt Tank for Durable Pavement Preservation

Achieve superior pavement preservation results with the Sinotruk HOWO Synchronous Chip Sealer, a high-performance road maintenance vehicle that simultaneously sprays asphalt binder and spreads aggregate chips. This synchronous technology creates a durable, skid-resistant surface that extends pavement life by 5-8 years.

Built on the reliable HOWO 4x2 chassis with an advanced PLC control system, precision heating, and hydraulic power, this vehicle delivers uniform, high-quality chip seal applications for highways, urban roads, bridges, and rural pavements.

The synchronous sealer solves traditional chip seal problems by spraying asphalt and spreading aggregate simultaneously, ensuring immediate embedment and optimal adhesion. This creates a strong mechanical bond that resists raveling, delamination, and moisture damage.
