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.
   Lightweight aggregate does not polish as it wears.
   Because it is light in weight 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.
