Figures 1, 3 and 5 show the deformation behavior of polymer blends, it was found that the linear viscoelastic
behavior at the initiation of the compression due to the relaxation of polymer blends (Sombat, 2004). The linear
viscoelastic region describes the resistance of the polymer blends to loading and thus rutting and cracking due to
