HC Deb 19 January 1993 vol 217 c174W
Mr. Llwyd

To ask the Secretary of State for Transport if he will make it his policy to secure the widespread use of porous asphalt on motorways and trunk roads in the United Kingdom.

Mr. Kenneth Carlisle

It is the Department's policy to use porous asphalt where it can be shown to be the most suitable and cost effective surfacing. A specification and advice note on porous asphalt are to be published shortly by the Department of Transport jointly with the Welsh Office, Scottish Office and Department of Environment (Northern Ireland). These documents will set out those situations where porous asphalt is likely to be suitable.
