HC Deb 28 March 1979 vol 965 c204W
32. Mr. Madel

asked the Secretary of State for Transport what is the nature and extent of research being conducted by his Department as to the durability of certain stretches of motorways before essential repairs are needed; and if he will make a statement.

Mr. Horam

A machine which can assess when essential repairs will be needed has been developed by the transport and road research laboratory for use in the United Kingdom. The laboratory is also doing research to develop road surfaces which last longer.
