IKO’s Permatrack Bridge Surfacing system has been used to resurface the Ouse Swing Bridge in Yorkshire.
Constructed in 2005 as part of the Selby Bypass, the bridge and its adjoining roads required resurfacing.
IKO’s Permatrack system was specified for its waterproof mastic asphalt wearing course, developed specifically for Bridge Decks. This offers improved material flexibility and maintains good rut resistance.
When laid, the product is not affected by water ingress or freeze thaw cycling and offers effective skid resistance when tested against requirements.
IKO was approached by Consulting Engineers Jacobs for the specification, which was installed by BriggsAmasco. The company’s machine installation equipment enabled a far quicker installation than the conventional method of hand laying.
The existing mastic asphalt surfacing and brdige deck waterproofing was replaced with Stirling Lloyd’s eliminator waterproofing system and IKO Permatrack.
IKO supplied 100 tonnes in 6 no. loads, enabling the 1,200m2 project to be completed in five days.
IKO Sales Director Marcus Lee commented: “IKO Permatrack is used extensively as the surface course for expansion joints on both raised structures and a wide variety of bridge decks.
Its advanced polymer modification makes it highly durable and resistant to deformation, and there is no compaction required. It also offers high stability and no impact sensitivity, which means it can easily accommodate structural movements without fracturing or cracking.”
