§ Chris GraylingTo ask the Secretary of State for Transport, Local Government and the Regions what recent estimate he has made of the cost difference between low and high noise road surfaces. [41653]
§ Mr. JamiesonA recent estimate by the Highways Agency suggests that there is very little difference in whole life cost between low and high noise road surfaces. This estimate takes account of both the initial cost and the expected life of the surface, which can both vary between individual products and applications.
