  • Floating asphalt pavement system
    Patent number: 3993412
    Abstract: Tennis courts, basketball courts, volleyball courts, all weather running tracks and other similar recreational areas having defects in their surfaces are resurfaced by laying multiple layers of a free floating flexible material over the defective surface and then applying a standard asphalt resurface over the top layer of free floating flexible material.
