By oxidizing the unoxidized asphalt composition, the particle size of the ground tire rubber and the devulcanized rubber was reduced, which increased the surface area so as to expose the non-vulcanized sites for reaction. The oxidization process released oils in ground tire rubber that reduced the viscosity of the unoxidized asphalt composition which improved resistance to oxidative aging and enhanced durability due to fine particle reinforcement. Based on the data presented in Table 1, asphalt not suitable for use due to unsatisfactory penetration point and unsatisfactory durability can be combined with ground tire rubber and devulcanized rubber and oxidized to obtain an oxidized asphalt composition useful for roofing applications.

Each of Sample A to Sample H is separately mixed with a limestone filler to obtain an asphalt filled coating having 10% to 90% by weight of the limestone filler, and 10% to 90% by weight of the oxidized asphalt composition. Each asphalt filled coating is applied to a coated coupon. The physical properties of the coated coupons are measured to evaluate the performance of the asphalt filled coatings in roofing applications. Each of the coated coupons exhibit a tensile strength, a tear strength, and an elastic recovery that is either suitable or superior (relative to conventional asphalt filled coatings without the rubber compositions) and thus the asphalt filled coatings are determined to be useful for roofing applications, including, without limitation, roofing shingles. The process for preparing the coated coupons is performed on a standard manufacturing line for roofing shingles. All percentages by weight are based on a total weight of the asphalt filled coating.
