Problems solved by technology
[0003] At present, the optical fiber is applied to the pavement mainly by the method of first building the road and then opening the hole to bury the optical fiber, which increases the difficulty of the construction and also increases the construction period, which not only increases the construction cost and reduces the construction efficiency, but also is not conducive to the stability of the road structure. sex

The invention discloses a method for laying a sensing optical cable in an asphalt pavement structure, and the method comprises the steps: spraying a first emulsified asphalt layer on a road base, marking a first optical cable position on the first emulsified asphalt layer, laying a first surface layer optical cable according to the first optical cable position, and laying a first asphalt pavement layer above the first surface layer optical cable; spraying a second emulsified asphalt layer on the first asphalt road material layer, marking the position of a second optical cable on the second emulsified asphalt layer, laying a second surface layer optical cable according to the position of the first optical cable, and laying a second asphalt road material layer above the second surface layer optical cable; and spraying a third emulsified asphalt layer on the second asphalt road material layer, marking a third optical cable position on the third emulsified asphalt layer, laying a third surface layer optical cable according to the third optical cable position, and laying a third asphalt road material layer above the third surface layer optical cable. The construction cost is reduced, and the construction efficiency and the structural stability of the road are improved.
Description
technical field [0001] The invention relates to the technical field of road engineering, in particular to a method for laying optical fibers in an asphalt pavement structure. Background technique [0002] With the development of optical fiber and optical fiber communication, a new type of sensing technology such as fiber grating technology has emerged. It not only has the advantages of high resolution, high sensitivity, high reliability and long service life, but also has strong corrosion resistance, It has the characteristics of strong anti-electromagnetic interference and anti-humidity interference, and has been used in the detection of civil engineering structures. [0003] The current optical fiber used in pavement laying mainly adopts the method of first building the road and then burying the optical fiber, which not only increases the construction difficulty but also increases the construction period, which not only increases the construction cost and reduces the const...
