Project Details
Description
The works are required to maintain the safety and integrity of a section of the A90 (southbound) between Invergowrie and Longforgan. Resurfacing works are required as the carriageway is currently displaying various defects, such as routine patches and cracking.
The scheme is 1.35km in length, with an area of 1.2ha.
Construction activities and the associated plant and machinery required are as follows:
- Implementation of Traffic Management (TM) and marking out site (TM plant);
- Removal of existing surfacing and milling to agreed depths (planer, wagon, lorries);
- Resurfacing to the existing road levels using TS2010 aggregate, AC binder and AC base (paver, roller);
- Reinstatement of road markings, linings, and studs (lorries/wagons and plant); and,
- Removal of TM.
The proposed construction is programmed to be undertaken and completed within the 2025-26 financial year for approximately nine overnight shifts. TM will comprise of lane closures with a night-time convoy system in place.
