Fiber synchronous chip seal refers to a new type of road construction and maintenance technology in which a fiber-added synchronous chip sealing truck simultaneously sprays asphalt binder and fibers, then spreads crushed stone on top, and after rolling forms a new wearing course or stress-absorbing intermediate layer. Fiber chip seal improves the aggregate particle size and asphalt content of the chip seal, and adds a certain amount of fiber so that it forms a grid-wrapped structure with the asphalt and crushed stone, thereby greatly improving its tensile and crack resistance and effectively stabilizing the aggregate, so as to improve the crack resistance of the chip seal when used as a stress-absorbing layer and its wear resistance when used as a surface wearing course. Moreover, the addition of fiber can absorb asphalt in the voids of the seal, reduce free asphalt, and to some extent retard the flow of asphalt, preventing the occurrence of high-temperature bleeding. This method has been applied on many national and provincial trunk lines in China, achieving obvious social and economic benefits and receiving unanimous praise from relevant units; in addition, this method has gone abroad and been applied on the Moscow-Vladivostok national trunk line of Russia's M55 Highway, completing 360,000 square meters of fiber chip seal construction, and was highly praised by the Far East Regional Highway Administration of the Ministry of Transport of the Russian Federation.
