National Petro Product

• Composition: CSS-1 consists of bitumen droplets dispersed in a water phase with a cationic emulsifier. 
• Setting Time: It is a slow-setting emulsion, meaning it takes time to dry after application, allowing for longer workability and better coating of aggregates. 
• Applications: Used in tack coats, base stabilization, fog sealing, dust control, and specialty applications. 
• Standards: CSS-1 is manufactured according to standards like ASTM D 2397M-13. 
• Advantages:
  • Can be used with moisture aggregates. 
  • Low application temperature, reducing energy consumption. 
  • Can be used in various weather conditions, extending the application period. 
  • Does not require heating or petroleum solvents like cutback bitumen. 

Solid Cutback Bitumen refers to a form of bitumen that has been modified to improve its workability and application properties, typically by dissolving it in a solvent. It is used in road construction and maintenance to provide a more flexible and easily workable material. 

Cut Back Bitumen is a type of bitumen that has been diluted with a solvent to reduce its viscosity, making it easier to handle and apply at lower temperatures. The solvent evaporates after application, leaving behind the bitumen to perform its intended function.

Polymer Modified Bitumen (PMB) is bitumen that has been enhanced with polymers to improve its performance characteristics. The addition of polymers alters the physical properties of bitumen, making it suitable for a wide range of demanding applications.
