Rhinoplast Preservation

Norbreck Road is 1.4km long urban road in the north of Blackpool. The surfacing material is all SMA, with about 70% being 14mm SMA and the rest in a newer application of 10mm SMA. This scheme was highlighted due to the SMA surfacing approaching its ‘end of life’ performance, having already suffered from patch repairs, and it is a low congestion risk. The surfacing was generally in a sound condition with some areas marked up for repairs prior to treatment. Blackpool Council wanted to maintain the low noise characteristics of the existing SMA surfacing in the urban area and minimising disruption caused by conventional maintenance methods.

Services supplied

Application of RHiNOPHALT® began once the road was swept and all gullies were masked off. Spraying time for both sections of road was 1 hour for the first night shift and about 1.5 hours for the second shift. Curing was 1 hour on the first shift, which is rapid for this time of year, and was assisted by the wind speed. Curing on the second shift was a little longer at 1.5 – 2 hours, mainly due to the wind dropping even though the air temperature was a little warmer and humidity lower. Line marking commenced once the RHiNOPHALT® was fully cured and the road was opened well before the closure end time of 06:00.

Outcomes

Maintained the low noise characteristics of the existing SMA surfacing in the urban area minimising disruption caused by conventional maintenance methods.
