Effects of Mineral Additives on the Durability of Coating-Grade Roofing Asphalts
The effects of 14 mineral additives on the durability of coatings made from three asphalts were evaluated in accelerated durability machines. The durability of the coating is largely a function of the asphalt used; it increases, generally, with coating thickness and mineral additive concentration. Additives with flat, platelike particles finer than 75 microns in diameter were most effective in producing coatings of increased durability. Complete dispersion of the additives in the base asphalts is necessary to produce consistent results.
