Solution to the Access Control Problem of Highway Engineering Evaluation System

At present, the conventional detection and management methods used in the construction of expressways in China cannot adapt to the quality demand of modern road construction. Therefore, it has become an effective method to evaluate and test the quality of road construction. The project aims to ensure the data security and traceability ability in the road construction quality monitoring system. Through the comprehensive analysis of the whole process of the project construction, the traceability system of the original road construction project is improved by block chain. This project plans to build a “public chain + chain” double-chain system of “public chain+chain” based on “public chain+chain”, so as to solve various problems in the construction of domestic expressway projects. The newspaper was public and contacted through trade unions. The research results are of great significance to ensure the traceability and traceability of expressway engineering in China.
