Project Details
Description
Works are required to maintain the safety and integrity of a 2,018m stretch of the A78, south of Kilwinning in North Ayrshire covering an area of 2ha. Resurfacing works are required on the southbound carriageway due to surface defects and structural defects identified across the carriageway. These include fretting, potholing, alligator cracking, rutting and some isolated cracks.
Construction activities will consist of structural inlays, ranging in depth from approximately 30mm-300mm. Treatment will involve using TS2010 surface course. The activities will be as follows:
- Implementation of Traffic Management (TM);
- Milling out the existing material to the proposed treatment depths by road planer;
- Paver will be used to lay the new road surface and inlays using TS2010 surface course 10mm aggregate and AC binder and base if required;
- Road will be flattened and compacted using a roller;
- Reinstatement of road markings, linings and studs; and,
- Removal of TM.
The following (but not limited to) plant/machinery/vehicles may be used throughout the scheme:
- Planer;
- Paver;
- Wagon(s);
- Bitumen tank;
- Extrusion liner;
- Paint tanker;
The proposed works are programmed to be completed within the next financial year (from April 2025) during night-time hours for a duration of 10 days.
TM is still to be confirmed but will likely consist of full night-time lane closures on the southbound carriageway. A diversion route will be put in place utilising the B714, A78 and A738.
