The practical performance of the mastics for pavement purposes is analysed. The study is focused on the effectiveness of different sepiolite clays and their mixtures, combined with the fire retardant action of aluminium trihydrate (ATH). Our results indicate that the performance against fire is favoured by the high porosity and density of the sepiolite, and by its lack of affinity with bitumen. Mixing two types of sepiolites we obtain a mastic which presents a synergism between the good cohesion/adhesiveness of one of the formulations and the improved fire performance of other one.7enginfo:eu-repo/semantics/restrictedAccessjournal article10.1016/j.conbuildmat.2011.12.055BitumenFlame retardantsPavementsRheologyCivil and Structural EngineeringBuilding and ConstructionGeneral Materials Sciencehttp://www.scopus.com/inward/record.url?scp=84855516321&partnerID=8YFLogxK
