Table 5: _Cont._The viscosity measurement results confirmed that regardless of the CA average particle size, the viscosity of BWM increases as the ASE content increases. This suggests that an increase in the ASE content prevents precipitation and segregation in raw material components and suppresses flow-ability, thus resulting in increased viscosity. In addition, it was confirmed that the CA average particle size of 16.0 \(\upmu\)m has the highest viscosity, and the specimen applied with the particle size ranging from 5.0 \(\upmu\)m to 1.0 \(\upmu\)m except for the CA average particle size of 16.0 \(\upmu\)m exhibits the characteristic that the viscosity increases as the CA average particle size decreases. This is because plasticizer absorption and friction increase when the surface area of contact between the CA and other raw materials increases as the CA average particle size decreases.
