Rediset LQ is a liquid variation of AkzoNobel's Rediset WMX, a warm mix additive that allows the processing of asphalt mixes at lower temperatures and the compaction of asphalt mixes containing high contents of reclaimed asphalt pavement (RAP).
More than 38,000 tons of WMA with Rediset LQ have been laid since K-Five began paving in early October.

More than 38,000 tons of WMA with Rediset LQ have been laid since K-Five began paving in early October. The paving season for 2011 was concluded in early December and resumed in early April 2012. A temporary taxiway, designed to have a life span of three to five years, was completed in early November to enable connection of existing taxiways with new pavement, thus ensuring that this new section was fully open to aircraft operations.

At this point, about 50% of the permanent taxiways project has been paved, with completion scheduled for early June 2012. All told, Danna estimates that a total of 65,000 to 70,000 tons of WMA with Rediset LQ will be laid.
