HC Deb 16 January 1987 vol 108 c326W
Mr. Neale

asked the Secretary of State for Transport what steps he takes to monitor the performance of materials used in the construction of motorways and trunk roads to ensure specifications are producing the required result.

Mr. Peter Bottomley

The Department's engineers are closely involved with the construction and maintenance of motorways and trunk roads and monitor the performance of in-service roads. When a problem with a material is encountered on any site, the performance of that material on other sites is investigated and corrective action taken if required; consideration is also given to the need to revise any standards or specifications.
