Evaluación de la cohesión de betunes modificados con polvo de neumáticos

摘要: This article reports on a study of crumb rubber-mediated improvement in bitumen cohesion, analyzed with the UCL method. UCL, procedure developed to characterize bituminous binders, evaluates cohesion obtained by adding certain amount or mastic standard mix aggregate. method was chosen because it can be used assess containing rubber added either wet dry process. In process is combined as if were fine aggregate; i.e., and binder are blended during manufacture, laying compaction. process, prior mixing when mix, has already been modified. The effect digesting this mixed material use also present study. A comparison (with without digestion) processes showed latter more effective, particularly via microscopic dispersion.
