The product is intended for polymer-bitumen binders (PBB) used for road construction, for mastics, and
The main components providing elasticity and wear resistance to the road pavement, including rutting
resistance, are PBBs manufactured by mixing oil road bitumen and styrene-butadiene copolymers (SBC) in
the presence of plastifiers. The main problem of PBB is partial compatibility between copolymers and
bitumen components, affecting the system’s stability during storaging and transporting for more than 5
hours in hot condition. MONAMET B3 modifier allows improving the compatibility of PBB components so
that the obtained PBB materials remain stable for at least three days. The improved compatibility of PBB
components qualitatively influences properties of the obtained PBBs, which in turn positively influences
final properties of road pavements. Stability of PBB components opens up new opportunities for PBB
storaging and transporting in heated condition with concerns for the quality of the material delivered to
asphalt plants. Furthermore, the PBB preparation time is reduced by 2 to 3 times depending on the road
bitumen grade used as the feedstock, which, besides increased PBB quality, significantly lowers
expenditures for manufacturers of this kind of binders.
MONAMET organo-modified nanoclay by METACLAY JSC, dispersed in binder to intercalated condition, is
responsible for ensuring the PBB system’s stability. Added together with MONAMET B3 modifier, the
organophilic clay is combined with both SBC and road bitumen components, with all the PBB components
permeating nanoclays interlayer spaces, creating a kind of network of numerous linkages, similar to
framework structures formed when mixing with polymers.
Modifier for Road Bitumen and Polymer-Bitumen BindersThe product represents a polymer compatibilizer for road bitumen and polymer-bitumen binders based onorganophilic nanoclay – modified montmorillonite.
