Written question asked by Christopher Chope (Conservative) on Monday, 23 May 2022, in the House of Commons. It was due for an answer on Thursday, 26 May 2022 (named day). It was answered by Trudy Harrison (Conservative) on Thursday, 26 May 2022 on behalf of the Department for Transport.

Roads: Bitumens

Question

To ask the Secretary of State for Transport, what assessment his Department has made of the proportion of road surfacing carried out on (a) national roads in England and (b) local roads in England which incorporates warm mix asphalt; and whether steps are being taken to increase the use of warm mix asphalt.

Answer

Warm mix asphalt is National Highways preferred choice of asphalt for all its road schemes and it is accelerating its use as standard across its supply chain as part of a drive toward net zero carbon emissions. More information can be found on National Highways’ website on Net zero highways: https://nationalhighways.co.uk/netzerohighways/.

For local roads, it is for each individual local highway authority to assess which parts of its network need repair and what standards and materials, including warm-mix asphalts, should be applied, based upon their local knowledge and circumstances.
