Main features of Jointmaster

Rebated / inlaid repairs:

Jointmaster® is a fully approved system for repairing all cracks, joints and surface defects in the highway. Developed to treat bituminous and concrete surfaces, defects are repaired and reinstated with Jointmaster, a bituminous compound which eliminates the original failure mode (movement) by virtue of its flexible and elastic nature.

The Process:

Image
  • Approved by BBA under HAPAS (Highway Authorities Products Approval Scheme) as a flexible crack repair system for highways since 2007.
  • Decades of experience on motorways, trunk roads and local authority highways.
  • Replacing failed asphalt with high polymerised, flexible jointing repairs for a permanent watertight seal.
  • Tested and approved skid resistant finish even after extensive trafficking.
  • Suitable for all sites: asphalt, concrete and overlayed concrete. Urban or rural. City, motorway, country lane or housing estate.
  • Tested and approved for rut resistance from heavy traffic, HGV’s and Buses.
  • High outputs minimise disruption. Sites can be reopened to traffic at the end of each shift. Other site traffic can transverse the repairs once cooled.

Outputs: 

  • Outputs of up to 1000 Lin.m are achievable in a day for rebated work and many thousands of metres for overbanding. The type of site and type of work will dictate what this figure will be
  • Higher outputs such as motorway work can be achieved with additional resource 
  • Longitudinal recessed work 800-1,000 Lin.m per day 
  • Transverse joints 300-400 Lin.m per day 
  • Overseal banding up to 4,000 Lin.m per day

Minimising disruption

Traffic Control:

Works can be carried out under lane closure, Stop and Go, or traffic lights. Single file traffic can usually be maintained. 

Working Hours:

In busy areas, work can be carried out during restricted working hours. On motorways and other traffic sensitive roads, we usually carry out the work over a nighttime lane closure. The road is fully open to traffic the next morning. Work areas can be opened to traffic at the end of each shift, leaving a trafficable surface during the daytime before we return the following night to continue the work. 

Key Points of jointmaster :   • BBA HAPAS approved  • Treat all crack types  • Concrete & Asphalt substrates  • 5 Year minimum expected life  • Motorway use M25, M3, M4, A1  • Flexible polymerised bitumen

It’s odd to think that bitumen is one of the oldest engineering materials known to man, having been in use for at least 8,000 years. Sumerians as far back as 6,000 BC were using naturally occurring bitumens in a thriving ship building industry and one of the oldest written accounts of the use of bitumen appears in the Bible (Gen:11-1-4) where it was used as an adhesive jointing material. With all the advances in technology over the past 8,000 years, we still strive to overcome one of the oldest conundrums facing an engineer, ‘How do I repair a cracked road surface?’ The answer to this question is simply ‘flexibility’.

Jointmaster has been specifically designed to combat the effects of reflective and fatigue cracking, providing a flexible range of treatments to accommodate the requirements of the most demanding location. Jointmaster is a system with independent approval from British Board of Agrément (BBA) under the Highway Authorities Product Approval Scheme (HAPAS) and a system which is delivered and installed by a company with certification under ISO9001:2015 , ISO14001:2015 and ISO45001:2018. 

Jointmaster is the market leader in crack repair technology and the clear choice for most of the Highway Agency motorway and trunk road contracts, it fully complies with Clause 711 volume 1 of the Manual of Contract Documents for Highways Works (MCHW).

How can Jointmaster help? 

Jointmaster was purposefully designed to meet the BBA HAPAS requirements for flexible inlaid crack repairs.  

The formulation is specifically designed to be flexible (to absorb future movement), to bond to the surround, and to withstand the effects of modern day traffic.  

All of these factors resolve problems associated with reflective and fatigue cracking.  

It is a polymer modified rubber/bitumen binder, mineral fillers, graded granite aggregate and chopped fibres. It can stretch and compress with the natural movement of the carriageway without cracking or tearing. BBA tests show that the compound is capable of elongation exceeding 30% yet withstand heavy trafficking, whilst maintaining the necessary skid resistance values. Full details of the tests follow and can be seen in the attached BBA/HAPAS certificate found in 'Downloads'.  

Jointmaster stops the further ingress of water into the substrate through the cracks, which extends the useful life of the surface, as pavement deterioration is substantially reduced.

BBA HAPAS requires approved systems to meet certain criteria.  

The criteria for an inlaid crack repair system includes skid resistance testing both before and after wheel tracking tests. This was a vital requirement stipulated by the Highways Agency to combat motorcycle skidding accidents on longitudinal joint and crack repairs.  

Rutting tests were required to ensure the materials installed were of adequate strength to support the surrounding asphalt surface. Without this support strength, the area of the repair could be the initiator of a rutting problem.  

Tensile bond test the ability of the material to stick to the surrounding surface. It’s no good if the material avoids cracking down the middle but pulls away from the edge of the road. 

Perhaps most crucially of all is Elongation. This particular test is only a requirement of BBA HAPAS inlaid treatments complying with type ‘F’ or ‘Flexible’ grade repairs. The alternative approval type ‘H’ or ‘Hard/High Modulus’ requires no flexibility. With Elongation, the material is required to extend to plus 30% of its original width when pulled apart before showing any signs of cracking or de-bonding. This is element that ensures further movement in the road is accommodated.
