Innovative Crack & Seat for A75 Dumfries Bypass
Scotland TranServ on behalf of Transport Scotland will use the innovative crack and seat technology to improve the A75 Dumfries Bypass this weekend (7/8 June).
Using this sustainable approach will mean far less waste material is produced on the £350,000 project.
Ken Bryden, Scotland TranServ’s Network Area Manager for Dumfries & Galloway said:
“Deterioration in the road was caused by deep cracks in the rigid base of the carriageway. This permeated right through to the surface layer of the road, making for a bumpy ride for drivers. Crack and seat introduces hairline cracks into the base layer before constructing the surface layer on top. This allows the base layer to expand and contract freely without disturbing the road surface.”
In order to carry out work on the westbound carriageway it will be necessary to close the road between the Dancingknowe Roundabout and Lockerbie Road roundabout between 19:00 on Friday 6th June and 06:00 on Monday 9th June. Further convoy working will be required overnight on the eastbound carriageway between 19:00 and 05:00 the following morning on both Monday 9th and Tuesday 10th June. The first phase of work will take place from the layby to the A709. Work has been specifically scheduled in this way in order to create as little disruption for commuters as possible.
The work will be undertaken by DG First, Scotland TranServ’s specialist road maintenance contractor in Dumfries and Galloway.
Crack and Seat technology is being used at a number of locations across Dumfries and Galloway, with a project at Castle Douglas to follow in the next few weeks.
Carol Walker, Scotland TranServ’s Environment Manager said:
“Where possible Scotland TranServ is trying to re-use waste materials and cut down on the amount we sent to landfill. For a full five months 100% of construction and demolition material was reused, meaning that we didn’t send any such waste materials to landfill. Combined the crack and seat schemes have already saved enough haulage miles to stretch from Glasgow to Tokyo.”
For the westbound work over the next weekend a diversion will be in place through Dumfries, while for the overnight work on the eastbound carriageway on Monday and Tuesday, a convoy system will be in operation.
Russell Rennie, Scotland TranServ’s Contract Director concluded:
“Across Dumfries and Galloway, working with DG First, we are improving the surface of the main economic arteries carrying freight to and from the region’s important ferry ports. As well as improving the road surfaces for this year-round traffic we’re also setting a good first impression for the thousands of visitors who will head through the area in this summer of Homecoming, the Commonwealth Games and the Ryder Cup. This is part of our long-term goal, as is delivering an improved, more sustainable trunk roads network on behalf of our client, Transport Scotland.”
