EK35 Top Coat
The EK35 top coat is applied directly to the runway surface to create an erosion resistant surface which minimizes dust emissions and potential Foreign Object Debris (FOD).
4″-6″ EK35 Stabilized Well Compacted Aggregate Surface Course
EK35 is blended into the upper 4″-6″ of the surface course to increase longevity, strength, stiffness and uniformity of runway surface.
Well Compacted Aggregate Base Course
The well compacted aggregate base course should consist of proper gradation aggregate and be compacted to a minimum of 95% of its maximum dry density prior to installing the overlying EK35 stabilized surface course.
The subgrade is the compacted native soil in which the base course is laid upon and acts as the foundation for the runway.
