A comparison study between micro bauxite powder and nano bauxite powder for rutting and physical properties

Abstract EN

The main purpose of this paper is to compare the physical properties of Micro Bauxite Powder (MBP) and Nano Bauxite Powder (NBP) as modifiers of asphalt binder.

This comparison is to evaluate which modifier has a better ability to improve the performance of the asphalt binder.

The comparisons include the tests such as penetration, ring and ball, ductility, and viscosity performance.

In addition, the evaluation of aging conditions noted that micro bauxite powder and nano bauxite powder could resist and delay the aging which can promote pavement durability.

In general, the investigation of the performance of micro bauxite powder and nano bauxite powder modified asphalt binder showed that NBP had a significant impact on binder greater than MBP.

The best condensation that could be considered as the optimum content was 5% for both modifiers.
