Project Details
Description
Resurfacing works are required to maintain the safety and integrity of a section of the A90 carriageway (northbound) located south of Drumlithie as the existing carriageway is displaying surface defects and structural defects such as routine patches, rutting, and cracking.
Treatment will include inlays ranging from 110mm to 280mm to remove deterioration and reinstate binder layers, with deeper partial reconstructions (350mm) applied in localised patches where more extensive deterioration is present. The scheme will replace the existing pavement with new asphalt surface course and AC binder layers to ensure consistency, durability and long-term performance. Road studs and lining will be refreshed as part of the scheme.
The following plant and machinery will be required:
- Planer
- Paver
- Miller
- Wagon
- Roller
- Traffic Management (TM) plant.
The scheme is approximately 2.08 kilometres (km) long, with a total area of approximately 1.15 hectares (ha).
The construction is programmed to be undertaken and completed within the 2026-2027 financial year, proposed for June 2026. A contraflow system will in place with works undertaken during night-time working hours for three weeks.
