Britpave to review Highways Agency’s soil stabilisation guidance

Infrastructure industry trade association Britpave has announced that the Highways Agency has given it responsibility for updating and revising its guidance on soil stabilisation.

Britpave has said that this is the first time that the Agency has tasked an external organisation with updating its guidance.

Under the agreement, Britpave’s Soil Stabilisation Task Group will take responsibility responsibility for maintenance and development of ‘HA74 Treatment of Fill and Capping Materials using either Lime or Cement or Both’. The advice note forms part of the Design Manual for Roads and Bridges and provides guidance on the use of lime and cement to stabilise capping materials for highway works and slope repairs, covering site investigation, design and construction.

“This is an important step for the Highways Agency,” said Highways Agency geotechnical team leader Alex Kidd. “In accordance with our recently published Technical Standards Strategy, we recognise that practitioners are often best placed to ensure the current validity of guidance documents and we wish to encourage industry to development and potentially own the guidance required to deliver Agency needs. This is thought to be a the first time that the agency has given responsibility for one of its advice notes to an outside organisation and we are confident that it is in line with our strategic objectives.”

“Advice Notes such as HA74 are meant to be practical guidance documents. It therefore makes sense that those with practical, hands-on experience are the ones ensuring that the guidance is kept fully up-to-date with current best industry practice,” said Britpave Soil Stabilisation Task Group chairman Al McDermid.

The Agency will still have a role within the revision as Kidd is a member of the Britpave task group.
