Abstract:
The experiments were conducted to study the effects of mixing temperature, rubber waste particle size, and rubber waste-to-asphalt ratio on viscosity, flexibility, impact strength, adhesion and salt spray resistance properties of the coating. All materials were mixed by stainless steel ball mill at mixing temperatures of 35+-5 ํC (room temperature) and 75+-5 ํC. The rubber waste particle size of 100, 300 and 600 micron and rubber waste-to-asphalt ratio at 0:0, 1:2, 1:1, 2:1 and 1:0 were used. The results showed that the properties of coating made from rubber waste depended on the mixing temperature, rubber waste particle size, and rubber waste-to-asphalt ratio. When the mixing temperature was increased, the viscosity, adhesion and salt spray resistance of coating were increased. However, the viscosity was increased but the adhesion and salt spray resistance were decreased when the rubber waste particle size and rubber waste-to-asphalt ratio were increased. Lastly, under the conditions used in this work, flexibility and impact strength of coating did not show any dependency on the mixing temperature, rubber waste particle size, and rubber waste-to-asphalt ratio.
