Estudo viscoelástico de misturas asfálticas frescas e envelhecidas com agregado sinterizado de argila calcinada

Abstract: RESUMO Os revestimentos asfálticos dos pavimentos flexíveis, em função do ligante betuminoso presente em sua composição, possuem comportamento mecânico dependente de vários fatores, dentre eles: processo de compactação, temperatura e taxa de aplicação de carregamento. Várias são as reações passíveis de ocorrerem nos principais constituintes dessas formulações asfálticas, dentre estas, pode-se citar a oxidação, endurecimento físico e perda de voláteis. No caso do ligante asfáltico, o envelhecimento aumenta a vi… Show more
