Lincolnshire highways programme enhances roads across the county

A major programme of highway improvements is continuing across Lincolnshire, with two large-scale maintenance initiatives already delivering significant benefits to roads throughout the county.

Motorists may have noticed fresh road surfaces, temporary speed restrictions and roadworks in recent weeks as crews carry out surface dressing and Re-Tread projects designed to improve road conditions and extend the lifespan of the highway network.

Surface dressing, often referred to as “chip and tar”, involves preparing the road surface before applying a binding layer and covering it with stone chippings. The material is then compacted to create a protective layer that helps preserve the road and prevent deterioration.

Hundreds of Miles of Roads Receiving Treatment

Since the beginning of April, surface dressing teams have treated almost 873,000 square metres of road across Lincolnshire. This equates to around 96 miles of highway or an area comparable to more than 1,300 tennis courts.

The programme remains on schedule despite some disruption caused by wet weather, with the majority of works expected to be completed by the middle of June.

Cllr David East, executive member for highways, said: “The scale of what’s being delivered right now is huge.

“We’re protecting roads across the county in a practical, cost-effective way, and it means smoother journeys now and longer-lasting roads for the future. It’s exactly the sort of investment and work being done by Highways that makes a real difference to people in their day-to-day travels.”

Weather remains a key factor in the delivery of surface dressing works. The treatment can only be applied when road surfaces are completely dry, as moisture prevents the binding material from adhering correctly. As a result, rain can cause short-term changes to work schedules.

Drivers are also being reminded that newly treated roads may initially appear rough or uneven. Loose chippings are a normal part of the process and are gradually removed through a series of sweeping operations. Road markings and studs are reinstated once the surface has settled.

Temporary 20mph advisory limits are introduced during this period to help protect the new surface and reduce the risk of loose stones being displaced by passing traffic.

The purpose of surface dressing is preventative rather than corrective. By sealing the road surface and preventing water penetration, the treatment reduces the likelihood of potholes developing and can significantly extend the road’s operational life. Any surplus chippings collected during the process are retained for use in future maintenance programmes.

Recycling Existing Roads to Create Stronger Foundations

While surface dressing is suitable for roads that remain structurally sound, other sections of the network require more extensive intervention. For these locations, Lincolnshire is using an in-situ recycling process through its Re-Tread programme.

Rather than excavating and replacing large sections of road, specialist machinery recycles existing materials on-site. The upper layers of the road are broken up, processed, combined with stabilising agents and relaid to create a new, stronger foundation.

This approach reduces waste, lowers the need for transporting materials and cuts the environmental impact associated with traditional reconstruction methods.

In just a few weeks, approximately 8,000 tonnes of road material have been recycled through the programme rather than being removed and discarded.

The method also offers practical benefits, including faster completion times, reduced disruption for residents and fewer heavy vehicle movements.

The first phase of the local recycling programme is nearing completion, with only a handful of locations still to be finished, including sites on Gravecoat Lane in Quadring and in Sutton St James.

Meanwhile, planned works at Beck Bank in Gosberton Clough have been rescheduled to avoid conflicting with other nearby highway projects. Revised dates will be announced in due course.

Second Phase Scheduled for July

The next stage of the programme is set to begin on 27 July, with works planned in Thorpe St Peter, Kingerby, Norton Disney and Claypole.

Alongside road resurfacing and reconstruction activities, maintenance teams are also undertaking grip digging works along roadside verges. These drainage channels help direct water away from carriageways and into adjacent ditches, reducing standing water and helping to protect the road structure from future damage.

Together, the various maintenance measures form a comprehensive strategy to improve the county’s highways. Surface dressing helps preserve roads before significant deterioration occurs, in-situ recycling restores roads requiring structural repairs, and drainage improvements help prevent recurring issues.

Although much of the work may only be noticed briefly by passing motorists, the cumulative impact is contributing to ongoing improvements across Lincolnshire’s road network.
