Lightweight Chip Seal and Other Uses on Asphalt Road Surfaces
            
   When bonded to asphalt, structural lightweight
   aggregate chip seal creates a significantly improved
   asphalt bituminous surface treatment that is safer,
   more economical and longer lasting than conventional
   aggregates.  Wet or dry, road surfaces of lightweight
   chip seal provide superior skid resistance that is
   maintained throughout the surface life,
   because lightweight aggregate does not polish as it
   wears. Because it is lightweight there are trucking and
   handling cost advantages to the contractor.  Also,
   windshield damage and damage to headlights, and
   paint caused by "flying" stones is virtully eliminated with structural lightweight aggregate, thus
   avoiding costly insurance claims and motorist complaints.
