Studying the Applicability of a Modified Penetrometer to Measure the Creep Compliance of Asphalt Binders.
A solution for measuring creep compliance of asphalt binders is obtained by
testing samples using a spherical indenter at intermediate temperatures. The initial
assumptions considered a semi-infinite medium with no ...
Influence of nanosilica and diatomite on the physicochemical and mechanical properties of binder at unaged and oxidized conditions
(2016)
Modification of binders helps address common distresses in pavements by changing their essential properties. In order to further characterize the role of additives in these changes, a set of nanosilica and diatomite modified ...
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 ...
Evaluation of methodologies for aging simulation of asphaltic mastics in laboratoryAvaliação de metodologias para a simulação de envelhecimento de mástiques asfálticos em laboratório
(2017-07-01)
The aging in laboratory of asphalt mastics, which have mineral fillers, should be analyzed differently from existing procedures for asphalt binders. For samples with filler, it is suspected that the decantation of the ...
Desenvolvimento de ligantes asfálticos modificado com lignina como aditivo antienvelhecimento
(Universidade Federal de Minas GeraisUFMG, 2017-10-27)
Asphalt aging is an important problem, and research on anti-aging additives has been carried out to mitigate degradation by the effect of solar radiation. Lignin was selected as an anti-aging additive because of its ...
