§ Mr. George Gardinerasked the Secretary of State for Transport if he will estimate the approximate cost of replacing the present brushed concrete surface of the Reigate-Leatherhead section of the M25 with tarmacadam.
§ Mr. Peter BottomleyThe approximate cost which allows for overlaying with 100 mm of bituminous 597W material, ancillary works and traffic management would be some £3 million at present-day prices. This does not include any assessment of traffic delay costs over the period of the works which would be several months.
There will be no significant noise difference from an asphalt surface with similar skid resistance characteristics.
