And due to the small scale of the road, the closed construction will also bring great traffic pressure to the surrounding road network, and the noise, dust, exhaust and other things generated will also cause great harm to the surrounding environment; therefore, the prefabricated assembly technology emerges as the times require. The prefabricated assembly technology greatly shortens the construction time on site through a series of standardized processes, ensures the construction quality, reduces the pollution to the environment, and has become a hot spot in the research of pavement structure.
