Synchronous chip seal is a cost-effective surface treatment in which the asphalt binder and stone chips are spread onto the pavement at the same time by one machine. Because the binder is sprayed seconds before the chips are embedded, the aggregate bonds to fresh binder and adhesion can reach up to 70 percent, forming a dense waterproof and anti-skid surface layer. The method is widely used on expressways, national and provincial trunk roads, county and township roads, and urban streets, both as preventive maintenance and as the lower layer of pavement reconstruction. Compared with thin overlay, chip seal uses far less material, requires simple technology and provides excellent cost efficiency. Our crews complete the full process from road preparation, binder and chip spreading, rolling and sweeping to traffic opening, with material and equipment supplied as a package.
