Estudo da rigidez, da deformação permanente e da fadiga de misturas asfálticas com ligantes convencionais e modificados
(Universidade Federal de Santa Maria, 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 ...
Avaliação dos procedimentos para determinação de teor de ligante e granulometria em concretos asfálticos de diferentes faixas granulométricas e origens mineralógicas
(Universidade Federal de Santa Maria, 2017-07-13)
The verification of binder content and granulometry of asphalt mixtures are of great importance in the
technological control of the construction process. These ensure a good performance of the pavement
in its useful life. ...
Estudo laboratorial das propriedades mecânicas de misturas com diferentes cimentos asfálticos de petróleo produzidos no Brasil
(Universidade Federal de Santa Maria, 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 do comportamento à fadiga de misturas asfálticas aplicadas em campo por meio da teoria viscoelástica de dano contínuo
(Universidade Federal de Santa Maria, 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 ...
Estudo do comportamento de concretos asfálticos com diferentes tipos de agregados e cales
(Universidade Federal de Santa Maria, 2014-08-15)
Pavements are highly relevant structures in the current economic context and its performance
depends, among other factors, on the component of the materials of each layer of the structure.
One of the solutions studied ...
Estudo do efeito deletério da água em misturas asfálticas a quente produzidas no Rio Grande do Sul
(Universidade Federal de Santa Maria, 2019-02-21)
Asphalt pavements should provide users with safe and reliable transportation, however, agents such as traffic actions, weather conditions and inadequate maintenance result in the process of road deterioration. The water ...
Estudo do comportamento viscoelástico de concretos asfálticos convencionais e modificados através de ensaios de laboratório e de análise de desempenho
(Universidade Federal de Santa Maria, 2015-08-19)
Road transport is of great importance for many countries, in Brazil it can be even more extreme, by excessive movement of cargo through this modal. We know that the maintenance costs of roads are high, forcing researchers ...
Análise de desempenho à fadiga de misturas asfálticas por meio da simulação no software LVECD
(Universidade Federal de Santa Maria, 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 e da resistência ao dano de misturas asfálticas com ligantes modificados por borracha e polímero
(Universidade Federal de Santa Maria, 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 da deformação permanente de concretos asfálticos aplicados em campo
(Universidade Federal de Santa Maria, 2020-10-15)
Transport on highways, mainly on asphalt pavement, is crucial for many countries around the globe, being
relevant to the economic and social contexts of a country. Another key factor is the mechanical behaviour of
asphalt ...
