M25: Noise
The question
To ask the Secretary of State for Transport, what steps she is taking to (a) repair and (b) replace concrete sections of the M25 generating excessive noise.
Answered by Lilian Greenwood
Work is being planned to treat the concrete sections of the M25 with a new technique known as Next Generation Concrete Surfacing (NGCS) to reduce noise. The treatment involves repairing the joints between the concrete sections and then retexturing and scoring the concrete road surface itself. The overall effect of repairing the joints and treating the concrete surface will reduce noise. National Highways regularly monitors the condition of the concrete road surface and the joints to carry out repairs as quickly as possible whenever maintenance is required.
