M25 Bell Common Tunnel
Client: Costain/Capita
Consultants: Capita/Mouchel (on behalf of Highways Agency)
Site: M25 Bell Common Tunnel
Contractor: Aggregate Industries
Quantity: 22000m2
Product: CompoGrid® CG100 and SealoFlex
Date: July-November 2009

ARCDESO® was used to support Capita in their design of a 95mm asphalt overlay of a CRCP pavement through the Bell Common Tunnel on the M25.

CompoGrid® and SealoFlex (CompoGridSeal) were installed prior to the overlay to arrest reflection cracks that could develop in the bituminous layers.

21000m2 were installed over four nightshifts by specially trained operatives, using purpose-built applicators.  These machines are specifically designed to pre-tension and install reinforcement without creating wrinkles and folds.
