Laboratory investigations of materials for road and/or airport construction deserve special attention from researchers since they have shown to be essential to create materials able to ensure in service high long-lasting performances.

Abstract
Laboratory investigations of materials for road and/or airport construction deserve special attention from researchers since they have shown to be essential to create materials able to ensure in service high long-lasting performances. Moreover, the use of products deriving from recycling of waste materials is of extreme importance from an environmental and economical point of view. For these reasons and following previous research work in which the Authors developed a laboratory procedure for mix design of cement-bound mixtures, in this paper they present the results they obtained by focusing on the effects of different bituminous emulsions, used as additive, on volumetric mechanical and durability performances of such recycled cementbound materials. In summary, the complete set of experimental data shows that, by means an appropriate use of bituminous emulsions in terms of type and dosage, it is possible to produce recycled materials characterized by mechanical properties suitable to different design requirements.File | Dimensione | Formato | |
