AI Technical Summary

Technical Problem

In existing technologies, the intelligent road surface sensing unit and repair unit lack integrated design, resulting in poor damage signal transmission path and difficulty in accurately matching the release of repair agent with the location of cracks, which affects sensing sensitivity and repair efficiency.

Method used

The intelligent road surface material, which uses carbon-based nanomaterials and shape memory fibers, forms a three-dimensional conductive network. Combined with microcapsule repair agents and shape memory fibers, it achieves self-sensing and self-repair. The repair activation unit is triggered by the change in resistivity, and the passive and active repair of cracks are achieved in a coordinated manner.

Benefits of technology

It enables real-time monitoring and self-healing of road surface damage, reduces the frequency of manual inspections, improves road lifespan and economy, and has long-term cyclical repair capabilities.

Abstract

The invention relates to the technical field of intelligent pavements, in particular to a material for an intelligent pavement, a self-sensing and self-repairing intelligent pavement and an implementation method of the self-sensing and self-repairing intelligent pavement. The material for the intelligent pavement comprises a mixture of a matrix binding material, a self-sensing unit and a self-repairing unit, the mass of the self-sensing unit is 0.3%-1.5% of the mass of the matrix binding material, and the self-sensing unit is selected from at least one of a carbon-based nano material and short carbon fibers; the self-repairing unit comprises a microcapsule repairing agent and a shape memory fiber. The three-in-one framework of the intelligent surface layer, the induction monitoring network and the intelligent control system can realize self-sensing of the health state of the road surface; when a crack occurs at the position of the microcapsule, the microcapsule shell can be passively broken to release a repairing agent to fill the crack, and meanwhile, after a damage sign is found through self-sensing, the shape memory fiber can be triggered to actively repair.
