      <title>POROUS FRICTION SURFACE RUNWAY AT USNAS DALLAS, TEXAS</title>
      <link>https://trid.trb.org/View/56576</link>
      <description><![CDATA[The performance of the porous friction surfacing (PFS) on a runway at the U.S. Naval Air Station, Dallas, Texas, was evaluated. Runway friction measurements with a mu-meter, field permeability measurements, visual condition surveys, corings of the pavement for determination of asphalt binder properties, and an investigation of aircraft accidents attributed to hydroplaning were accomplished. The results of these investigations show that the porous friction surface is providing (1) a highly skid-resistant surface for high-speed jet aircraft operations; (2) an excellent surface with few visible defects; and (3) a minimum service life of 5 years with a potentially much longer life.

      <title>EVALUATION OF EXPERIMENTAL POLYURETHANE-COATED MEMBRANES</title>
      <link>https://trid.trb.org/View/23888</link>
      <description><![CDATA[This report describes an investigation conducted for the development of an improved flexible prefabricated membrane surfacing suitable as an expedient dustproofing and waterproofing medium for soil subgrades used as forward-area airfields and road surfacings. This was accomplished by means of: laboratory tests of PUC membranes, adhesives, and nonskid compounds to determine physical properties, and skid tests simulating C-130 braking action on nonskidcoated PUC membranes placed on a soil subgrade to determine skid resistance and durability.]]></description>
