Kianco Natural Bitumen Asphalt Product
 
>> Category:
Natural Bitumen Asphalt Grade
 
>> Product Code:
KMCBN-GMA-1080
 
>> Description:

Modifier for hot mix binders to achieve broader Useful Temperature Interval (UTI) and improve high temperature properties of bitumen. KMCBN-GMA was developed for use in conjunction with, or as a substitute for, polymers in asphalt.

 
>> Applications:

Natural Bitumen Asphalt Grade improves the high temperature properties of asphalt and is a reinforcing agent for hot mix asphalt (HMA). This grade has superior purity and a finer particle size distribution compared to conventional Gilsonite grades. It can be directly blended into the asphalt binder.

Natural Bitumen or Gilsonite Modified Asphalt (GMA) is inherently phase stable. GMAs produce paving surfaces with higher stability, superior rut resistance, improved resistance to water stripping, and reduced temperature susceptibility.
