Análise de desempenho à fadiga de misturas asfálticas por meio da simulação no software LVECD
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2019-07-11)
The understanding of the behavior of asphalt mixtures and their performance evaluations against the fatigue phenomenon are extremely relevant in the pavement scenario. Through these analyzes, it is possible to previously ...
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 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. ...
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 do comportamento à fadiga de misturas asfálticas aplicadas em campo por meio da teoria viscoelástica de dano contínuo
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2018-07-31)
The behaviour analisys of asphalt mixtures is extremely important in the paving cenarium, whose final objective is to improve the performance combined with resources saving. It is known that the fatigue cracking is the ...
Análise da influência da variação de temperatura no desempenho de pavimentos asfálticos à fadiga a partir do modelo S-VECD
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2019-07-12)
Asphalt mixes show a strong correlation between its temperature and its mechanical properties. In Brazil, it is used the DNER design method, which does not consider temperature in order to evaluate the behavior of asphalt ...
Caracterização avançada de ligantes e misturas asfálticas brasileiras
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2021-06-30)
The linear viscoelastic (LVE) and damage characterization of bituminous mixtures is imperative to analyse and design pavements. Bituminous mixtures inherit the viscoelastic behavior of bitumen. The bitumens used in paving ...
Misturas integralmente recicladas: comportamento à fadiga e degree of binder activity
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2019-07-11)
The brazillian road network, in general, have been presenting functional and structural shortcomings conducted by a constant growth of highway traffic over the years. Thus, the need for routine rehabilitation is essential ...
Estudo entre escalas de ligantes e misturas: investigação do comportamento viscoelástico linear e parâmetros de dano dos materiais asfálticos
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2023-04-06)
The most common distress in the asphalt coating layer of the country's highways are permanent
deformation in the wheel tracks and fatigue cracking. The phenomena of cracking and permanent
deformation that occur at the ...
Caracterização à fadiga de misturas asfálticas por compressão diametral e comparação com os resultados do ensaio de tração-compressão
