The storage moduli of bitumen–silica model composites obey a simple relationship: E′ = E′ 0 + A ϕψ, where ϕ is the filler volume ratio and ψ the bitumen–silica interfacial area for a unit volume of composite. This equation is experimentally varified taking various silicas of different surface areas or chemical surface reactivity. The influence of the interface properties on the mechanical glass transition temperature is also examined.
