摘要: Abstract Novel bituminous mastic formulations with performing viscoelastic and mechanical properties improved resistance to fire, are investigated. The practical performance of the mastics for pavement purposes is analysed. study focused on effectiveness different sepiolite clays their mixtures, combined fire retardant action aluminium trihydrate (ATH). Our results indicate that against favoured by high porosity density sepiolite, its lack affinity bitumen. Mixing two types sepiolites we obtain a which presents synergism between good cohesion/adhesiveness one other one.
