TARRC & WRAP Programme

TARRC supplies technical know-how and practical experience to WRAP Programme

Measuring tread wearTARRC is assisting Rubber Recovery of Barnsley by providing technical assistance and by running commercial vehicle tyre service trials as a part of the WRAP research programme. In the programme of work, which is designed to demonstrate that reclaimed rubber crumb can be used in high specification compounds such a tyre treads, TARRC mixes the specially treated rubber crumb into tyre tread masterbatch and then builds hot-cure retreaded tyres from the resultant material.

The reclaim material is being studied at 2 different loadings in the virgin compound: 40 and 50%. The materials were mixed during early February; the tyres were moulded in late February.

The rolling resistance of the tyres was measured on a test drum to ISO 18164 (2005). The tyres containing the reclaim rubber had rolling resistances roughly 20% lower than the control compound. This should result in a fuel saving of between 3 and 5%.

The fleet trials began in March and are expected to last between 6 and 9 months, ending in November/December. After an initial period of running, the tyres are measured every month to determine tread wear. It is too early yet to comment on the data.
