IKO’s Permatrack Bridge Surfacing system was specified to resurface the Ouse Swing Bridge. Built as part of the Selby Bypass, the bridge was opened in 2005. However, 10 years on and re-surfacing of the bridge was required, as well as to the roads either side.
IKO’s system was chosen because of its waterproof mastic asphalt wearing course specifically for Bridge Decks, which offers improved material flexibility and maintains good rut resistance. The product when laid is not affected by water ingress or freeze thaw cycling and provides the necessary skid resistance when tested against requirements.
Consulting Engineers, Jacobs, approached IKO for the specification, and BriggsAmasco was chosen as the installing contractor because of its machine installation equipment. This enabled a far quicker installation than the conventional method of hand laying.
The existing mastic asphalt surfacing and bridge deck waterproofing was stripped off and replaced with Stirling Lloyd’s eliminator waterproofing system and IKO Permatrack. IKO supplied a total of 100 tonnes in 6 no. loads and the 1,200m2 project was completed in just five days.
IKO Sales Director Marcus Lee, comments: “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.”
