Jointmaster Case Studies
Jointmaster Case Studies
A40 Whitney Oxfordshire
Client: Oxfordshire County Highways through a Main Contractor
Site: A dual carriageway bypassing Witney in Oxfordshire. Surface is 20mm Hot Rolled Asphalt
Problem: Fretting of centre line seam joint. Potential motorbike ‘stuck in a rut’ accident due to poor compaction of HRA at edge of each strip.
Solution: Jointmaster rebated repair 200mm wide by 20mm deep and some 50mm deep infill patches.
Facts and Figures
- 4,000 Lin.m of 200mm wide x 20mm deep
- 1.4m³ at 50mm depth
- Lane closure between 9.30am and 4pm
"As a customer, we knew we could rely on Jointmaster to provide a long-lasting repair, carried out with minimal disruption. This is a cost-effective system for restoring the profile of the surface, making it safe for motorcycles. The application was perfect for the job."
Holderness Road Hull City
Client: Hull City Council through PBS Construction
Site: Dual carriageways leading into the centre of the city. Surface; 40mm HRA over 40mm base course. Sub-base; C30 lean mix. Scheduled for surface dressing.
Problem: Reflective cracking from the sub-base and fatigue cracking in the wheel track.
Solution: Jointmaster rebated joint repair 200mm wide by 40mm deep combining BBA HAPAS approved 20mm flexible crack repairs with 20mm 'H’ grade base layer for high stress situations.
Facts & Figures
- 13,000 Lin.m of 200mm wide x 40mm deep
- Carried out under lane closures between 9.30am & 3.30pm
"In Hull we have a problem with reflective cracking appearing through overlaid carriageways from the concrete base. Jointmaster has provided a quick and efficient technique to solve this defect, while providing a smooth-running surface. We previously used Rhino about five years ago to repair deeper joints in similar circumstances which have held up well."
A11 Wymondham Bypass
The A11 Wymondham bypass is a busy dual carriageway with a CRCP (continually reinforced concrete pavement) construction. Linking the A14 with Norwich, this site is one of the main routes through East Anglia for freight transport between London and the seaports.
The design of the CRCP was cracking and over time some cracks had interlinked with resulting failure of the concrete surface.
Rhino Asphalt Solutions installed the BBA HAPAS approved Jointmaster system to repair the concrete surface to a depth of 40mm in a variety of patches and cracks both transverse and longitudinally.
M20 Operation Brock
Selected as a key partner on the M20 Operation Brock project, Rhino provided a range of critical repair solutions to enable the additional width of carriageway utilising the hard shoulder in the event of contra-flow.
BBA/HAPAS approved Jointmaster was the chosen product that, due to the unique flexibility, withstands the movement of the concrete pavement without the need to re-form expansion joints. Repairs to bay corners, mid-bay cracking, thin bonded repairs and bridge transition joints were all treated with this process.
Our BBA/HAPAS approved Ironmaster Manhole and gully repair process was used to replace much of the carriageway ironwork ensuring that the hard shoulder could be trafficked with confidence.
Rhino Asphalt Solutions installed the BBA HAPAS approved Jointmaster system to repair the fretted longitudinal seam joints in the asphalt mat. This left a safe running surface for traffic and maintained the integrity of the surface.
M90 Kinross, Scotland
To upgrade the M90, the existing overlaid concrete pavement has been resurfaced to improve ride quality and reduce regular maintenance ‘callouts’ caused by deteriorating reflective cracking in the asphalt surface. It was found that prolonged ingress of water had allowed the underlying concrete joints to spall. The damaged joints needed repairing before the new surface could be applied over a 4-year programme of renewal.
