Diseño de nuevos ligantes sintéticos a partir de materiales reciclados

Abstract

Pavements are made from a blend of mineral arid whith bitumen, named asphalt. This blend has suitable mechanical properties to whithstand traffic loads, in a wide range of temperatures and stresses. Bitumen technology had to adapt to new demands of a transport system which require more resistance and durability. With this aim, bitumen supplied for paving uses, are being modified through the addition of polymers. In any case, there are several special purposes in which bitumen is susbtituted by desing materials called syntetic binders. In general, synthetic binder is a blend of a mineral oil, resin and polymer. The end of this work is the desing and characterisation of syntetic binders with selected properties. This thesis will start with the study of the mechanical and thermal properties of the individual components, followed by the study of the binary mixtures: oil-resin, oil-polymer and resin-polymer.
