Synchronous chip seal technology aims to protect tires from asphalt, preventing them from being driven over newly laid waterproof layers.

These specialized vehicles—synchronous chip seal trucks—play a crucial role in road and bridge construction. The unique feature of synchronous chip seal technology is that it simultaneously sprays and spreads the asphalt binder and aggregate, ensuring full contact between the two for optimal adhesion. Compared to traditional methods, synchronous construction shortens the interval between spraying and paving, allowing aggregate particles to penetrate deeper into the binder, increasing coverage, and ensuring a more stable binder-to-chip ratio. This not only improves work efficiency and reduces the need for additional machinery but also lowers construction costs.
