Complex Modulus and Stiffness Modulus of Cold Recycled Mixes

Popis výsledku v původním jazyce

This article introduces part of the research done within the international project CoRePaSol focused on cold recycled mixes. Standard design for cold recycled asphalt mixes specifies the use of bituminous emulsions, foamed bitumen or hydraulic binders. In Central European countries, often the combination of cement and bituminous binder is used as the most preferable solution because of increased bearing capacity which can be provided by the final structural layer similarly to cement stabilized materials. For this reason it is expected that strength properties as well as stiffness are improved, nevertheless the strain-related behaviour explained usually by stiffness modulus, resilient modulus or complex modulus is not largely assessed. During the experimental study, cold recycled mixtures with bituminous emulsion or foamed bitumen and different cement content were assessed by the repeated indirect tensile stress test (IT-CY) evaluating different curing periods. Since the main objective
