MODIFIED BITUMEN

Prominent & Leading Manufacturer from West Bengal, we offer polymer modified bitumen and crumb rubber modified bitumen.

  • CRUMB  RUBBER MODIFIED BITUMEN

Supported by highly experienced professionals, we have emerged as an affluent organization for offering exclusive collection of Crumb Rubber Modified Bitumen. It can be used for wearing courses at heavy trafficked roads, busy intersections, bridge decks and roundabouts for increased life of the surfacing. This bitumen is processed as per the set industry norms under the guidance of skilled professionals. We offer this bitumen in different packaging option as per the requirements of clients. Our quality analyst tests our offered product on various predefined industry norms in order to ensure flawless at users end.

Features:

  • Lower susceptibility to daily & seasonal temperature variations

  • Higher resistance to deformation at elevated pavement temperature

  • Better edge resistance properties

  • Better adhesion between aggregate & binder ensure longer life, strength & stability

  • Higher fatigue life of mixes due to high elastic recovery

  • Delay of cracking & reflective cracking

  • Overall improved performance in extreme climate conditions & under heavy traffic condition

  • Better water resistance

  • Prevents rutting

  • Resistance to creep & higher indirect tensile strengthen surface course

Applications:

CRMB can be used for wearing courses at heavy trafficked roads, busy intersections, bridge decks and roundabouts for increased life of the surfacing.

  • POLYMER MODIFIED BITUMEN

We are providing our clients an excellent quality Polymer Modified Bitumen. Which meets the requirements in accordance with PMB of IS 15462-2004 specifications designed for pavement applications. Heavy traffic intensity in terms of commercial vehicles, overloading of trucks and significant variations in daily & seasonal temperature of the pavement have been responsible for early development
of distress symptoms like raveling, undulations, rutting, cracking, bleeding, shoving & potholing of bituminous surfaces. The offered range is processed in line with industry standard utilizing supreme class chemical compounds under the supervision of skilled professionals. This bitumen can be availed in various packaging options provided to our renowned clients, as per information laid down by them. Moreover, this bitumen can be availed at affordable prices from us.

Features:
 

  • Our PMB ensures

  • Durable surface characteristics

  • Excellent anti-stripping properties

  • High cohesiveness

  • High stiffness modulus leading to greater resistance to permanent deformation

  • Improved bonding between bituminous layers

  • Improved fatigue resistance than increased resistance to reflective cracks


Application:
 

  • Polymer Modified Bitumen can be used in asphalt mix designs which result in the manufacture of cohesive asphalt mix with good elasticity suitable for type of traffic. Special attention to be given to the temperatures while manufacturing, lying and compaction are performed.

Types of PMB & recommendation for specific use:
 

  • PMB 120: recommended for cold climate areas

  • PMB 70: recommended for moderate climate areas

  • PMB 40: recommended for hot climate areas
