Carriageway surfacing
5.—(1) Where any carriageway comprised in Work No. 1a and 1b, or any slip road, is to be resurfaced as part of the authorised development, TSCS is to be provided unless otherwise approved by the Secretary of State. Any material approved by the Secretary of State as low noise surfacing must have similar noise reduction properties as TSCS.
(2) Any subsequent resurfacing of any carriageway or slip road referred to in sub paragraph (1) must be carried out using low noise surfacing material with similar (or improved) noise reduction properties to the TSCS unless otherwise approved by the Secretary of State following consultation with the relevant planning authority.
