AI Technical Summary

Technical Problem

Existing technologies make it difficult to quickly distinguish on-site from reversible performance fluctuations caused by moisture in recycled cold patch materials compared to irreversible deterioration caused by aging, coating failure, and segregation, leading to misjudgments of quality. Furthermore, the test results are not sufficiently linked to construction treatment, making it difficult to provide direct decision-making basis for whether the material can be used, whether it should be used after correction, and when to open traffic.

Method used

A calibration sample set and a calibration target value set are constructed. By using state mapping parameters and a set of state constraint relationships, baseline and excitation condition data are collected. A state observation feature set is constructed, and combined with constraint decoupling analysis, a quality state index is generated, ultimately producing the open traffic time result.

Benefits of technology

It enables effective differentiation between short-term damp disturbance and irreversible failure under on-site conditions, improves the accuracy of quality analysis and the practicality of construction treatment, avoids misjudgment, and ensures the scientific nature of the opening time to traffic.

Abstract

The present application relates to the technical field of quality analysis, and particularly relates to a quality analysis method for regenerative cold repair material, which comprises the following steps: constructing a calibration sample set and a calibration target value set in advance, and constructing a state mapping parameter, a state constraint relationship set and an open traffic reference table according to the calibration sample set and the calibration target value set; then forming a controlled sample layer for a target sample, performing a baseline working condition collection and an excitation working condition collection, constructing a state observation feature group, and performing a constraint decoupling analysis combined with the state mapping parameter and the state constraint relationship set to obtain a quality state index, so as to effectively distinguish a short-time damp disturbance from an irreversible failure state under a field condition.
