In this study products different composites with multiblends of bitumen, recycled isotactic poly propylene (iPP) resin and poly ester reinforcement. The Effects of correlation length, interdiffusion-coalescence and segregated-networks phenomenon in composite's modulus were considered. Therefore it was specified that the modulus of these composites in addition to reinforcement's type, are in depend on toughness, viscosity and modulus of modified bituminous resins. These Experimental variations compared with Voigt and Takayanigie's models. The results showed that Takayanigi's model with 2-2.25 in adjustment parameters, predicate modulus better than Voigt.
