A614 Thorne Road sits on an embankment around three metres in height. The road/embankment was in need of urgent repair as a result of major flood damage in early 2020. This caused a failure to the embankment which was causing the carriageway to fail as it was slowly eroding.
All works, with the exception of the carriageway surfacing under a road closure, were carried out while the carriageway was still live, operating under three way temporary traffic signals. This was due to this route being used regularly as a diversion route for the closures required on the M62 works on the Ouse Bridge. It was vital that we achieved the advanced closure date for the surfacing closure. It was therefore critical the embankment construction works were safely executed, preventing undermining of the carriageway and further weakening the structure.
The scheme comprised reconstruction and widening of existing embankments using imported Class 6N granular fill following removal of the existing overgrown vegetation and tree stumps to each embankment, installation of new drainage systems including gullies, filter drains, catch pits and pre-cast concrete headwall, fencing, gates and VRS safety barrier, following removal of the existing. Repairs were made to a section of the existing VRS system which was retained that was found to be in reasonable condition.
The embankment reconstruction would be carefully undertaken in short sections, including excavation of the existing embankment to form a stepped detail and install the new, imported fill. Once the granular fill installation to the embankments were complete, topsoil was then applied to the entire area followed by grass seeding and the installation of new hedges and shrubs.
Maintenance tracks were formed using site won material at the bottom of each embankment, retained by the new fencing and accessed via the new gates. This therefore provides easy access for landscaping maintenance of the newly seeded topsoil to the embankments, hedges and shrubs.
Existing kerbs were replaced and new channels were installed to the carriageway, which was then resurfaced under a full road closure at the end of the scheme. Deep planed patch repairs were carried out adjacent the kerbline where the existing structure had failed and cracked due to the condition of the embankments prior to the contract. A fibreglass coated with polymer resin bituminous surfacing reinforcement grid was installed to the planed surface to provide support and stability for the new structure, prior to receiving the binder course and surface course.
Road markings and white reflectorised road studs were then installed to the newly finished surface, including the refresh of existing lining outside the extent of carriageway resurfacing to improve visibility and safety for drivers across this area.
Hundreds of 32 tonne wagons were employed to deliver the new fill material throughout the duration of the scheme. This process was made seamless by the onsite storage areas and temporary haul road formed to the area of works which allowed a constant flow of material to be installed at the highest output and avoiding the formation being exposed to the elements, particularly during seasons.
Browna Gill – October 2022 (4 weeks)
West Scrafton – October 2022/November 20022 (6 weeks)
Cravengate – March 2023/April 2023 (5 weeks)
Hunton Road – May 2023 (4 weeks)
This scheme included four individual projects; West Scrafton, Browna Gill, Cravengate and Hunton Road.
The project at West Scrafton was to dismantle a failed section of culvert and replace with a new reinforced concrete slab. The parapet wall was also taken down and rebuilt with the carriageway being resurfaced on completion of all repairs.
Browna Gill (Grinton)
The culvert and parapets on Browna Gill had collapsed. The repairs involved gathering the stones and rebuilding the parapet walls with concrete aprons following the installation of a new reinforced concrete culvert.
Cravengate was a full carriageway resurfacing job of approximately 2200m2. There were also some drainage work to carry out as well as general vegetation clearance.
Hunton Road (Scotton)
The project at Hunton Road was the installation of a new footpath adjacent to a housing estate. Scope of the works included cutting back and removing vegetation, excavation of the existing road, installing bullnose and edging kerbs and surfacing to the new footpath.
S278 works for a new Beal Homes development, Holderness Chase.
Carriageway and footway maintenance schemes around the East Riding.
Works began in Hermitage Road, Bridlington while also working in Flamborough down various linking streets, with completion of each site following the previous and working under a full road closure.
The Pocklington sites then commenced upon completion of Flamborough, in addition to Kingston Road, Willerby, the largest scheme of the package. Beverley Road, Anlaby, was completed last, where works comprised a variety of carriageway patching only and a section of full resurfacing, including a mini-roundabout.
Each site included a similar nature of works such as carriageway resurfacing to the full extent of streets, including ironwork adjustments/replacements, renewal of kerbing and channels. New road markings were installed to the new carriageway surface. A number of sites comprised full footpath driveway reconstructions, while a number only included footpath patches were identified as failing. Some sites also comprised renewal of the full kerb lines, whereas a couple of sites only identified minor kerbing replacements.
South Sea Road and Stottlebink in Flamborough comprised use of a ‘foam’ mix binder course in the carriageway, a highly recycled content asphalt providing a low manufacturing process carbon footprint.
Kingston Road was carried out under phased lane closures during the day time to carry out necessary civils such as kerbing and ironwork replacements. The carriageway was then planed and resurfaced under closures to various depths at night depending on the condition of existing surface. A number of deep excavation repairs were also required where significant failures in the existing surface were identified. New buff anti-skid was applied, including green anti-skid, to form cycle lanes.
Full reconstruction of the carriageway including new channels being installed and some minor footpath works.
Full Reconstruction of Carriageway
The majority of works carried out on Vane Street was a full reconstruction. We excavated roughly 800m2 of carriageway by 530mm below the existing sub-base. The new layer was then built up of 350mm type one stone laid in 100mm layer compacted at each layer, 90mm base AC-32 dense binder, 50mm binder course AC-20 dense bin and 40mm surface course.
Planing and Resurfacing of Carriageway
Roughly 120m2 of carriageway was planed to a depth of 90mm and we installed 50mm binder course AC-20 dense bin and 40mm surface course. Roughly 200m2 we planed to a depth of 40mm and installed 40mm surface course.
We installed new channels down either side of the carriageway (roughly 230m) and replaced any broken kerbs as well as undertaking minor concrete repairs in the vehicle access to the companies down Vane Street.
Installation of new traffic signals at Harlow Moor Road junction & Pannal Ash Road junction. Reconstruction of footways to accommodate shared use cycle path and altered kerbline. Carriageway resurfacing & line markings, installation of black, green bad buff anti-skid. Installation of new street light columns.
The works were to deliver the widening of Otley Road on the approach to Harlow Moor Road to facilitate the creation of a designated left turn lane on the western approach to Harlow Moor Road and designated right turn lane on the eastern approach to Harlow Moor Road.
In addition, there was the implementation of a designated off-road cycleway along Otley Road between Harlow Moor Road and Cold Bath Road utilising the existing footways in addition to the widening of the existing footways and creation of on-road cycleway facilities.
Both of the above involved upgrading the existing signalised junctions with new signals. Works also included site clearance, new kerbing, new footways, revised road markings and signing, street lighting, carriageway surfacing and drainage.
The works comprised the reconstruction of the footpath using Hull City Council supplied natural aggregate concrete Kellen paving and also the replacement of kerbs including a section of HCC supplied granite kerbs and channels, and some concrete.
In addition, works also involved the installation of multiple new gullies (connected into the existing sewer) to provide adequate drainage.
A Belisha beacon pedestrian crossing, including speed calming carriageway table, was installed outside of the new Arco building entrance to provide a safe crossing point for pedestrians.
The whole length of carriageway was resurfaced from beneath Myton Bridge to the Queen Street junction, including deep reconstruction in failed areas. Surfacing works also included a section of Queen Street by the A63 traffic lights, which also required concrete repairs prior to laying the new surface.
In addition to the above, an isolated section of the Queen Street carriageway (towards the pier) was also resurfaced during the main carriageway works.
The kerbline was altered at the junction with Queen Street to accommodate the carriageway layout redesign. This removed the junction at Humber Street with Queen Street, with new give way markings installed from the Queen Street south approach to the junction.
The scheme also included the installation of the Heald bollard safety system at the entrance to the busy stretch of Humber Street containing bars and other businesses. The Matador sliding bollard system prevents unwarranted vehicle access while being able to be opened remotely to allow authorised access.
This project involved the resurfacing of the carriageway from Hotham Road South to County Road South.
The works were completed under a road closure in two phases and there was a lot of involvement from the PBS site engineer during the planning of the existing tarmac and installation of new surfacing to ensure everything was laid to the correct level.
Additional works also involved resurfacing the stretch of footpath from the shops to the school. We came across a lot of soft spots that we quickly had to dig out and stone up for ready for the tarmac surfacing.
