The Birth of AROS™ (Anisotropic Rubber Obviated 
        Stress) 
           
In the early 1990's a team of development engineers from Lockheed Missiles & 
Space Corp. (LMSC) set out to investigate how their ceramic technologies might play 
into SBS production, particularly as it related to asphalt modification and 
pavement construction. 
          Non-traditional scientific evaluation of the failure mechanism(s) 
          associated with asphalt refractory composites (ARC) utilized in the 
          built infrastructure were pursued by the development team. Detailed 
          studies of the surface chemistry and petrographic character of clays 
          and aggregates were performed by scientists and engineers including 
          Orbiter (Space Shuttle) ceramic re-entry tile, team specialists; 
          specifically searching for opportunities to upgrade ARC interfacial 
          chemistry. Innovation ensued, targeting in particular the cost 
          effective improvement of four asphalt emulsion characteristics: 1) 
          adhesion, 2) cohesion, 3) early green strength and 4) water resistance 
          when employed in ambient cured, structural waterproofing and pavement 
          preservation systems.  
          The result of these past 14 years of development, spawned from LMSC 
          ceramic technologies, has produced an Asphalt Rubber binder (ARB) 
          technology that will serve as the long awaited 'paradigm shift' in 
          flexible pavement materials. This new innovation is referred to as 
          AROS™.  |
