Project Details

Description

The works are required to maintain the safety and integrity of the A75 between Drummore roundabout and Merklandsyde, covering an area of 11,700m². The works will involve resurfacing and installation of inlays to address structural defects and prevent further deterioration of the carriageway.

Construction will include the installation of concrete inlays at depths ranging from 30mm to 300mm, along a section of the A75. The surface will be milled off to these depths then resurfaced using a paver to match the same thickness of the material removed. A hot applied bitumen sealant will be used to seal the seal the junctions between the new and existing materials at both ends of the scheme.

Construction activities include:

• Implementation of Traffic Management (TM);
• Milling out of existing material
• Loader used to collect and move excess material within work area;
• Sweeper to collect loose material;
• Waste material will be removed from site;
• New materials will be laid including: binder, bituminous asphalt and tack bond, and compressed using a road paver and compacted by a roller;
• Road markings and road studs will be applied where necessary; and
• TM removal

The following plant/machinery/vehicles may be used throughout the scheme:

• Planer;
• Wagon(s);
• Sweeper
• Bitumen tank;
• Extrusion liner;
• Paint tanker;
• Paver; and
• Roller(s).

The proposed construction is programmed to be undertaken and completed within this financial year (April 2024 to March 2025) over six nights. Traffic management will consist of overnight road closures and a large diversion route travelling south along the B794 and along the A711.
