AI Technical Summary

Technical Problem

The traditional core pit repair method relies on manual operations, resulting in inaccurate feeding volume, uneven distribution of cold feeding, and difficult to control the compaction degree, resulting in poor compaction and flatness after repair.

Method used

A asphalt pavement core pit repair device is designed, including asphalt cold feed feeding assembly and striking assembly. The feeding assembly realizes the consistency of the feeding amount in each batch through the interval arrangement and alternating switches of the first partition and the second partition; the pressing assembly controls the pressing hammer to reciprocate in the vertical direction through the second drive member to ensure uniform compaction of the cold feed.

Benefits of technology

By accurately controlling the feed volume and uniform compaction, the compactness and flatness of the repaired core pits are significantly improved, the construction quality is improved, and the uncertainty of manual operation and subsequent maintenance costs are reduced.
