Research ArticleOpen accessPhrase in the titleApplication of Bio-Modified Montmorillonite Clay to Enhance Asphalt Oxidation ResistanceShahrzad Hosseinnezhad, Elham H. Fini, Taher M. Abu-LebdehThis study evaluates the effectiveness of using a Bio-modified Nanoclay additive (BNC) to reduce the oxidative aging of asphalt pavements. The study results through X-Ray Diffraction analysis showed that the modification of montmorillonite clay with bio-modifier increased the basal d-spacing of clay. The resulting nanoclay with increased interlayer spacing was chosen for application in asphalt binder. Rheological characterization of clay-modified … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 31 Mar 2018 · 9,054 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating the Efficacy of a Bio-Based Modifier to Improve the Rheological Properties of Recycled Asphalt ShinglesMohammed Jawad, Elham H. Fini, Taher M. Abu-LebdehThis study investigates the use of Bio-Binder, derived from swine manure, as an additive to improve rheological properties of bitumen extracted from recycled asphalt shingles. Test results show that adding Bio-Binder to Recycled Asphalt Shingles (RAS) leads to reduced viscosity, modulus shear complex G*, relaxation time RT and segregation. Results illustrated that the derived Bio-Binder additive can remove the negative … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 11 Mar 2017 · 7,146 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating Effects of Application of Silica Fume to Reduce Asphalt Oxidative AgingNader Abutalib, Elham H. Fini, Sassan Aflaki, Taher M. Abu-LebdehThis paper investigates the feasibility of using silica fume to enhance the rheological properties of asphalt binder. It has been widely reported that asphalt binder oxidation is one of the phenomena that reduces the service life of asphalt pavement by negatively impacting its rheological properties. This in turn can lead to a more brittle pavement which is more prone to … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 22 Apr 2015 · 8,485 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating Bio-Char as Flow Modifier and Water Treatment Agent for Sustainable Pavement DesignRenaldo Walters, Shamim A. Begum, Elham H. Fini, Taher M. Abu-LebdehThe life expectancy of Asphalt Binder (AB) has been negatively impacted by the harsh bombardment of Ultraviolet (UV) rays. UV rays cause asphalt to oxidize faster, which results in the deterioration of asphalt's rheological characteristics that can lead to pavement distresses. This paper investigates merits of bio-char to improve asphalt aging susceptibility by blending one control binder (PG 64-22) and … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 22 Apr 2015 · 9,049 accessesView PDFCite
Research ArticleOpen accessIn the abstractENHANCING ASPHALT RHEOLOGICAL BEHAVIOR AND AGING SUSCEPTIBILITY USING BIO-CHAR AND NANO-CLAYRenaldo C. Walters, Elham H. Fini, Taher Abu-LebdehThe life expectancy of Asphalt Binder (AB) has been negatively impacted by the harsh bombardment of UV rays. UV rays cause asphalt to oxidize faster, which results in deterioration of asphalt rheological characteristics that can lead to pavement distresses. This study investigates the impact of bio-char and nano-clay of asphalt rheological properties. Two nano scale materials were used for this … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 24 Mar 2014 · 10,525 accessesView PDFCite
