Abstract: A method for constructing an activity surface comprising a plurality of binder coatings interspersed with layers of particulate rubber. A tack coating preferably of asphaltic material, is applied to establish a good bond to the underlying foundation material. Subsequent binder coatings are of a latex liquid with a small quantity of surfactant added to enhance the penetration of the coating. A sealing coat is applied to seal the upper surface and to mechanically screen the harmful effects of sunlight. Each coating of latex is permitted to dry before applying a subsequent layer of rubber particles.

Abstract: A method for constructing an activity surface comprising a plurality of binder coatings interspersed with layers of particulate rubber. The first two binder coatings are of diluted emulsified asphaltic material to establish a good bond to the underlying foundation material. Subsequent binder coatings are of a styrene butadiene and water mixture with a small quantity of surfactant added to enhance the penetration of the coating. A sealing coat is applied to seal the upper surface and to mechanically screen the harmful effects of sunlight. Each coating of diluted styrene butadiene is permitted to dry before applying a subsequent layer of rubber particles.
