Polymer modified bitumen (PMB) (PMB JTG F40)
Polymer modified bitumen (PMB) is produced as per Chinese standard PMB JTG F40 from bitumen, SBS-polymers and additives based on unique technology developed by PROFBIT R&D team. Product range includes following grades: SBS PMB I-A, SBS PMB I-B, SBS PMB I-C, SBS PMB I-D.
PMB is used in construction, reconstruction and maintenance of roads and highways, bridges and airfields. PMB use makes it possible to prolong service life of the road surface and reduce the cost of its operation and maintenance due to PMB advanced characteristics against standard road bitumen: increased resistance to deformation, increased resistance to aging, increased resistance to rutting and cracking.
