NICHIPHALT HDS is a polymer modified asphalt type III.
It contributes to the high durability and long lifetime of the paving.


Compared to polymer modified asphalt type II, NICHIPHALT HDS has the following features.

  1. Because a higher dynamic stability will be obtained, it will be ideal for paving roads that are subject to ultra-heavy traffic or that are required to have an ultra-long life.
  2. Resistance to cracking will also be improved.
  3. The workability during the paving construction is the same as for normal modified asphalt.


  • Surface layers and base courses of roads subject to heavy traffic
  • Locations subject to traffic congestion such as intersections and bus stops
  • Locations such as docks, truck terminals and piers where heavy vehicles operate
  • Grooving pavement
  • Airport paving
