Additives for each bituminous binder of bituminous composite material

摘要

An additive for each bituminous binder of a bituminous binder capable of reducing the bitumen binder viscosity of the bituminous composite material by application of an alternating magnetic field for healing cracks in the paved road and deep microcracks in the asphalt, Of the magnetic iron oxide particles can be melted in a quick and convenient manner and are not improved in particular in order to obtain each bituminous binder of bituminous composite material which can be used for cracking of asphalt structure in the field There is no doubt. This is accomplished by forming an additive comprising at least a portion of magnetic iron oxide nanoparticles having an average size of 1 nm to 300 nm coated with fatty acids.
