Safe work in Surrey

Although a lot of surface dressing work as well as other roadworks were cancelled during the UK lockdown, one Nynas customer, Hazell & Jefferies Ltd of Oxford, were able to convince their clients that they could keep working safely under the tight restrictions.

By implementing mitigating procedures such as hiring buses to carry staff to sites and working in close cooperation with their clients and suppliers, Hazell & Jefferies managed to keep their scheduled work programme going and still adhere to the lockdown rules.

Hazell & Jefferies use both intermediate and premium grade bitumen emulsion from Nynas for surface dressing. During the latest surface dressing season, which has largely coincided with the pandemic, Nynas delivered volumes of the polymer modified bitumen emulsion products Nynas Fleximuls and Nynas Duramuls in line with pre-pandemic projections.

“Volumes have held up well. We have successfully delivered the forecasted volume provided by Hazell and Jeffries at the start of the year despite the pandemic and resulting restrictions," says Nynas Sales Manager Chris Rhodes.

A major surface dressing project on the important southern trunk road A31 near Farnham in Surrey is one example of contracts carried out during the lockdown.

The importance of interlayer bond coat application during pavement construction

With our collective duty to ensure sustainable and environmentally responsible solutions, it is more important than ever that the road construction industry strives to get things right first time and build structures to last. That implies new structures, as well as maintenance interventions, must be effectively designed and the installation must truly reflect that design.
