Next work requirements

Continue to increase investment in maintenance projects.

Municipalities should attach great importance to poor road sections and continue to increase investment. Where the technical condition index PQI of expressway pavement is less than 92, and the technical condition index PQI of ordinary national and provincial highways is less than 80, the municipality shall put forward corresponding rectification measures and give written feedback. It is necessary to formulate a scientific and reasonable maintenance plan, implement control measures, and make every effort to improve the quality of road conditions.

Strengthen the management of maintenance project plan

The maintenance project plans of expressways and ordinary provincial highways should be worked out quickly, and all units should make in-depth analysis of the test data, make scientific decisions, ensure the right medicine, and effectively improve the road conditions. Do a good job in the implementation of the common national highway maintenance project plan, popularize and apply the "four new" and energy saving and emission reduction technologies according to local conditions, standardize the management of maintenance projects, and complete the review and approval of design documents before the end of May 2024.

Strengthen industry supervision and implement supervision and guidance.

Municipal transportation departments should earnestly perform their duties of industry supervision and guidance, strictly supervise the business units and road sections that are not in place and have poor road quality within their respective jurisdictions, and urge all maintenance measures to be put in place.

Further strengthen the quality control of maintenance projects.

All units should further strengthen the quality management of maintenance projects, strictly implement the maintenance construction specifications and operating procedures, strengthen the quality sampling of raw materials and construction process, and strictly implement rectification measures for problems found in the construction stage and quality defect period.
