Non-demolition type reforming and refitting construction method

The invention discloses a non-demolition type reforming and refitting construction method. The method particularly comprises the following four steps: (1) acquiring information data of old road traffic conditions; (2) evaluating the diseases and defects of an old road; (3) formulating an operation scheme for reforming and refitting the old road, and performing construction; (4) evaluating and tracking the refitting effect. When the construction method is used for reforming and refitting an urban old and damaged road with a rigid surface layer, the resources of the old road are fully and reasonably utilized, so that excellent service quality performance is obtained; the service life period of the refitted road is long; furthermore, compared with a mode of dismantling the old road and then building a new road, the construction method greatly reduces old structure demolition work load and resource consumption and greatly shortens the construction period; therefore, the construction method corresponds with the de
