Caracterização à fadiga de misturas asfálticas por compressão diametral e comparação com os resultados do ensaio de tração-compressão
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2022-06-09)
The study of fatigue performance of asphalt mixtures is of great importance to prevent this distress in road pavements, whose need is highlighted in the current context of Brazilian paving, which begins the implementation ...
Estudo da rigidez, da deformação permanente e da fadiga de misturas asfálticas com ligantes convencionais e modificados
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2018-11-22)
In Brazil, there are two most recurrent defects found on highways: permanent deformation and cracking due to fatigue. Among the most varied causes, the formation and propagation of cracks in the asphalt coating occurs as ...
Estudo da rigidez e da resistência ao dano de misturas asfálticas com ligantes modificados por borracha e polímero
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2019-07-10)
The quality of Brazilian highways, generally constituted by asphalt concrete, is inadequate to the constant and heavy flow of vehicles that circulate daily. Because of this and considering that they are the main means of ...
Estudo laboratorial das propriedades mecânicas de misturas com diferentes cimentos asfálticos de petróleo produzidos no Brasil
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2018-02-28)
The evaluation of the behavior that different petroleum asphalt cements (CAP) give to the
mixtures becomes important due to the direct relationship between the quality of the
pavement and the performance of the binder. ...
