Projeto e implementação de ensaio de fadiga por tração-compressão direta (uniaxial) para avaliação de dano em misturas asfálticas

Abstract: RESUMO No país, são dois os mais recorrentes defeitos encontrados nas rodovias: deformação permanente e trincamento por fadiga. Dentre as mais variadas causas, a formação e propagação de trincas no revestimento asfáltico ocorrem em consequência das repetidas solicitações do tráfego que, com o tempo, reduzirão drasticamente a vida de serviço do pavimento, por exemplo, facilitando a penetração de água nas camadas granulares da estrutura e acelerando sua deterioração. Além disso, os ensaios mais comumente utiliza… Show more

“…The modification of the asphalt composite participants for the region aims to solve the above problems, however, one must take into account the repeated load transmitted to the coating during vehicle traffic, intrinsic action the pavement fatigue life [7]. To estimate the fatigue life of asphalt mixtures, there are laboratory tests that seek to simulate the conditions of road application and those seeking a reasoned approach [8]. Most fatigue test results have been obtained through simple bending tests, in which stresses or deformations are repeatedly applied until the prismatic specimen breaks or is structurally compromised [9].…”
