Proposals for modification of Iranian bitumen to meet the climatic requirements of Iran

Effect of climate change on asphalt binder selection for road construction in Italy

“…Given these premises, the aims of this paper are double: first obtain a map useful for the choice of the asphalt binder for road construction within the whole Italian area, as already done in other countries by some authors (Aflaki and Tabatabaee, 2009;Al-Abdul Wahhab et al, 1997;Hassan et al, 2008;Khalil et al, 2009;Marciano et al, 1997). At the same time, analyzing temperature time series for trend detection, the second objective of this work is to provide a tool for the selection of the asphalt binder that fulfills the road performance requirements during the 20 year service life even in transient climatic conditions.…”

Ageing Performances of Asphaltite Modified Bitumens; Comparisons with Equivalent Petroleum Bitumens

“…Several researchers have studied the composition and mechanical properties of various modified bitumens (Huang and Shu 2009;Kök et al 2011;Yildirim 2007;Aflaki and Tabatabaee 2009;Aflaki et al 2014).…”

Evaluation of the mechanical properties of natural asphalt-modified hot mixture

“…Widyatmoko and Elliot [3] used TLA and Uintatite to modify bitumen and showed that Uintaite or TLA caused an increase in the complex modulus (G*) and a reduction in the phase angle (d), indicating an increased elastic response. Aflaki and Tabatabaee [4] indicated that bitumen modification with gilsonite cause an increase in asphalt binder stiffness accompanied by intermediate and low-temperature deterioration. Huang et al [5] suggested introduction of an intermediate layer between the aggregate and asphalt binder in the HMA mixture as a novel method by which to mitigate the stress and strain concentration.…”
