Emulsified asphalt is an essential environmentally friendly material for road construction and pavement maintenance. It is widely used for prime coat, tack coat and seal coat in new asphalt pavement projects. It is also commonly adopted in preventive maintenance of old asphalt roads, including slurry seal, micro-surfacing, Cape seal and fine surfacing construction.

Asphalt pavement belongs to the flexible pavement structure system with comfortable driving performance and good shock absorption. In practical road engineering, the base course can adopt flexible materials, rigid cement concrete, or semi-rigid hydraulic stable materials to adapt to different road bearing capacity and construction conditions.

With excellent fluidity and permeability, emulsified asphalt can effectively seal micro cracks on the base course during prime coat construction. It prevents water penetration and avoids common pavement damages such as base loosening, water erosion and road settlement.

As an ideal interlayer bonding material for tack coat treatment, emulsified asphalt firmly combines upper and lower pavement layers. It enhances the overall structural integrity and prevents pavement delamination, sliding and cracking.

In slurry seal and chip seal construction, emulsified asphalt provides both strong aggregate bonding and waterproof protection. It forms a dense protective layer to resist water erosion and surface abrasion.

In slurry seal and micro-surfacing maintenance projects, emulsified asphalt is fully mixed with qualified aggregates and evenly paved on the original pavement to form a thin, uniform and durable wearing layer. The treated pavement presents a smooth and brand-new appearance, effectively improving road surface performance. This thin overlay offers excellent waterproof performance and greatly extends the service life of asphalt roads.

Emulsified asphalt supports cold construction without heating. It reduces energy consumption and exhaust emissions, achieving energy-saving and eco-friendly effects. Meanwhile, it eliminates high-temperature construction risks and improves on-site safety for construction workers.

Due to its outstanding advantages of safety, environmental protection, energy saving and high efficiency, emulsified asphalt has been widely promoted and applied in modern road construction and pavement maintenance.

With the continuous upgrading of road maintenance technology, emulsified asphalt will have broader application prospects. We are committed to optimizing product quality and construction solutions to promote the high-quality development of the road engineering industry together with global partners.
