Detailed Product Description
(Polymer Modified Bitumen)
Thisinvention relates to the process for the preparation of a polymer andrubber based modified binder which is useful for the construction ofroads catering to heavy traffic and also for the formation of airfieldsand surfacings, besides its use as binder for stress absorbing membrane(SAM) and stress absorbing membrane interlayer (SAMI) for sealing ofcracks, preventive maintenance of flexible pavement and delayingreflective cracking. Modified Bitumen performs better than ordinaryBitumen in high rain fall area and in situation where the aggregatesare prone to stripping.
- Improves resistance in cracking resulting in stronger and more durable overlays even in extreme climatic conditions.
- Reduces deformation on the roads even at temperatures of ( 50-70 degrees C)
- Polymer and Rubber based modifer binder extend life of pavement by 50-70% compared to conventional bitumen.
- PMB act as a multigrade bitumen and are economical when life cycle cost is taken into consideration.
