A Waterproof Mastic Asphalt Wearing Course for a Bridge Deck

Along with re-surfacing, inspection, showed signs of wear and tear on the bridge surface areas too. Consulting Engineers, Jacobs, approached IKO for the specification, and Galliford Try won the tender. BriggsAmasco were chosen as the installing contractor. IKO’s Permatrack Bridge Surfacing system was chosen - a waterproof mastic asphalt wearing course for Bridge Decks containing both polymer and epure (Trinidad Lake Asphalt) modifications to the bitumen binder, which offers improved material flexibility and maintains good rut resistance. Existing mastic asphalt surfacing and bridge deck waterproofing was stripped off and replaced with Stirling Lloyd’s eliminator waterproofing system and Permatrack.
