Investigation of nano ulexite mineral effects on mechanical behaviour of warm mix asphalt pavements

Abstract

Investigation of nano ulexite mineral effects on mechanical behaviour of warm mix asphalt pavements Research paper Tuba Kütük-Sert, Resul Ekrem Günbey Investigation of nano ulexite mineral effects on mechanical behaviour of warm mix asphalt pavements The research presented in the paper shows that further investigations on additives used in the warm mix asphalt technology are needed. It was observed that the negative effect of adhesion loss in asphalt mixes produced by warm process can be reduced by adding ulexite mineral nano particles to a commercial additive. The Marshall stability, Indirect tensile strength modulus, and moisture susceptibility, were tested for this purpose. Based on the analysis of results, it can be seen that the WMA mixture production temperature can additionally be reduced, and that lower compaction energy is needed during placement of such mixtures, which results in energy savings.

Determination of the Social Contribution of Sustainable Asphalt Mixes

“…Different synthetic products have been created to reduce environmental impacts when paving road works, and other natural products have been reappraised that can reduce the manufacturing and laying temperature of asphalt mixes. This has generated warm mix asphalts (WMA), which reduce polluting gas emissions and the energy needed to produce the mix and pavement construction processes [5][6][7]. Additionally, studies have demonstrated the technical effectiveness of incorporating recycled asphalt pavement (RAP) compared to traditional hot mix asphalt (HMA) in promoting recycled material use.…”

Investigation of textile waste usage in stone mastic asphalt (SMA) mixtures

“…Therefore, the design of highway networks that requires large capital expenditures is very important [1,2]. A satisfactory pavement design should be sufficiently serviceable, durable, resistant to permanent deformation, economical, and eco-friendly [3][4][5]. On a global scale, flexible pavements are the preferred type of highway superstructure [6][7][8].…”
