Surface cracking and fretted joints destroy surface integrity, decreasing structural strength which leads to premature failure of asphalt pavements.
Deficit budgets are forcing pavement engineers to preserve the value of their highway asset by using innovative maintenance systems to treat cracking and fretted joint failure at the surface to prevent water ingress into the foundation layers of the pavement.
Jointscreed is a screed applied two-part crack and fretted joint repair system for pavements. The process has unique benefits in comparison to similar systems as it requires no milling of the existing carriageway and is typically traffic-ready 15 minutes after application.
Part 1 is a highly polymerised, flexible infill material which fills and supports the edges of the crack or fretted joint.
Part 2 incorporates high PSV aggregate and seals the repair ensuring that it is watertight and provides a finished surface/repair with a high skid-resistant value.
Jointscreed will repair cracks and fretted joints in all asphalt pavements up to a width of 40mm including those in high stressed areas such as junctions, traffic islands and severe bends. The crack or fretted joint is prepared by blowing hot compressed air into it before being infilled with Part 1. Part 2 is then applied in band widths of 100/200mm.
Benefits of using Jointscreed:
- no milling required
- rapid curing time – traffic-ready with 15 minutes
- reduces CO2 emissions – no waste for landfill
- quick application – minimising disruption and traffic management costs
- high skid-resistant values
