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 ...
Incorporation of synthetic macrofibres in Warm Mix Asphalt
(Lavoisier, 2018-06)
The reinforcement of asphalt concrete with fibres is not a common practice in the pavement field. Although some research papers refer to the use of microfibres, the behaviour of asphalt concrete incorporating macrofibres ...
Development of asphalt emulsions incorporating waste lubricating oil
(Associação Brasileira de Petróleo e Gás, 2015)
The aim of this study is to develop asphalt emulsions incorporating used lubricating oil (OLUC), as a
modifier agent, to produce stable emulsions and resulting in cost-effective and environmentally friendly
product ...
Comparison of the n-Alkanes and Polycyclic Aromatic Hydrocarbons Concentrations in the Atmosphere during the Preparation of Warm and Hot Mixtures Asphalt for Pavements
(SOC BRASILEIRA QUIMICASAO PAULO, 2012)
Asphalt binder is used in the production of hot mixes asphalt (HMA) for paving and, due to the high temperatures used, generates fumes thatcontainn-alkanes and polycyclic aromatic hydrocarbons (PAH). Asphalt mixes prepared ...
Improvements on asphalt mixtures rutting performance characterization by the use of low shear viscosity
(Springer, 2012-07)
The relationship between the rutting performance of dense asphalt concretes and the low shear viscosity (LSV) of different asphalt binders was analysed in a previous work. A LSV limit was found for the original asphalt to ...
Effect of Aging on the Properties of Asphalt and Asphalt Mixtures
This article presents the results of the analysis of the effect of aging on the properties of asphalt and asphalt mixtures. The objective of this study was to compare the properties of the original asphalt and aged asphalt ...
