The Introduction of Micro - & Nanodispersed Fillers into the Bitumen Binders for the Effective Microwave Absorption (for the Road, Airfield & Bridge Pavements)

In this paper, the means of improving the efficiency of heating bituminous binders modified with micro- and nanodispersed fillers under the influence of microwave is described. The carbon nanomaterials (multi-walled carbon nanotubesis in particular) were selected upon the analytical review of the effectiveness of various electrically conductive and magnetically sensitive fillers in micro- and ultradispersed form to drive the efficiency of heating a bitumen binder in the microwave field. The experimental of the study included the preparation of a bitumen binder samples with the addition of electrically conductive and magnetically sensitive fillers, and specifically those selected on the basis of theoretical studies of multi-walled carbon nanotubes and various types of ferrite waste from metallurgy. The influence of modification of bitumen samples on the rate of their heating by electromagnetic microwave radiation is analyzed upon the obtained thermal heating coefficients. It is shown that the combination of small carbon nanotubes and magnetosusceptible waste additives provide the fastest and most uniform heating, and the optimal ratio of the components in the bitumen binder and mastic to ensure effective absorption of microwave energy coatings.
