Problems solved by technology

The existing prefabricated pavement technology is based on the traditional construction technology. Basically, prefabricated slabs are laid on the base layer first, leveled by mechanical components, and then grouted at the bottom of the slab. This process has complicated procedures and a long adjustment period. The control is difficult, the grouting volume and pressure are difficult to control, and the cost is high.

Abstract

The invention discloses a novel airport fabricated pavement flexible transition layer system and method, and relates to the field of fabricated airport pavements. A sealing layer and a flexible coiled material are spread on the top surface of a court road base layer, the flexible coiled material is mechanically paved, and further the top surface of the court road base layer is leveled through professional spreading equipment, and a coiled material bonding surface is provided; and the laying and pasting of the coiled material are conducted at the same time through laying and pasting professional equipment, and the top face is further leveled. According to the flexible transition layer system and the method, the flatness of the top surface of the court road base layer is further improved, the waterproof performance of the pavement is improved, the seal coat protects the base layer and is free of laying of coiled materials, and the laying and bonding efficiency of the coiled materials is improved; and meanwhile, hard contact between prefabricated plates on the coiled materials and the base layer is avoided through the coiled materials, the stress concentration at the bottom of the plate is reduced, the stress state of the bottom of a prefabricated pavement plate is improved, and the stability of the fabricated pavement is further improved.

Description

technical field [0001] The invention relates to the field of prefabricated airport pavement, in particular to a novel airport prefabricated pavement flexible transition layer system and method. Background technique [0002] In the airport prefabricated concrete pavement system, the pavement of the prefabricated slabs on the top surface has strict requirements on the flatness and joint surface of the lower base. The existing prefabricated pavement technology is based on the traditional construction technology. Basically, the prefabricated slabs are first laid on the base layer, leveled by mechanical components, and then grouted at the bottom of the slab. This process has complicated procedures and a long adjustment period. The control is difficult, the grouting volume and pressure are difficult to control, and the cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a new type airport assembly type pavement flexible transition...
