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. |
