4. Results and Discussion 4.1. Analysis of Optimal Tack Coat Oil Volume Three types of tack coat materials (matrix emulsified asphalt, SBS-modified emulsified asphalt, and SAE) were subjected to an inclined shear test at 25 °C. The sprinkling volumes of the three emulsified asphalts were 0.4 kg/m2, 0.6 kg/m2, 0.8 kg/m2, 1.0 kg/m2, and 1.2 kg/m2, respectively. Finally, a polynomial curve was fitted to these test data. Finally, a polynomial curve was fitted to these test data.
