Polymer Modified Bitumen PMB 70 - Technical Specifications

Key Characteristics of PMB 70

1. High Temperature Performance: Designed to perform effectively at temperatures up to 70°C. This makes it resistant to rutting and deformation under hot conditions, such as in high-temperature regions or during hot summers.

2. Improved Flexibility: Provides increased flexibility, allowing it to better withstand thermal stresses and prevent cracking.

3. Polymer Modification: Typically modified with elastomers like styrene-butadiene-styrene (SBS) or other polymer additives, which enhance the elasticity, cohesion, and durability of the bitumen. This modification helps improve its resistance to cracking and rutting.

Main Applications Of Polymer Modified Bitumen PMB 70

PMB 70 is used in a variety of applications where high temperature stability, flexibility, and durability are essential:

1. Highways and Major Roads: Widely used in high-traffic highways and roads due to its resistance to rutting at high temperatures and heavy traffic loads. It enhances road durability and reduces maintenance needs.

2. Bridges and Elevated Structures: Ideal for bridges and overpasses, which are exposed to temperature fluctuations and high traffic. The enhanced flexibility helps prevent cracking.

3. Urban Roads and Industrial Areas: Suitable for urban roads and industrial zones where heavy vehicles frequently travel. PMB 70’s resistance to deformation makes it a preferred choice for these areas.

4. Airport Runways and Taxiways: Used in airport pavements where high resistance to rutting and cracking is necessary due to the heavy loads from aircraft and high-temperature exposure.

5. Warm and Hot Climate Regions: PMB 70 is suitable for regions that experience warm to hot climates, as it can withstand high temperatures without losing its structural integrity.

PMB 70 is a polymer-modified bitumen designed to offer high-temperature resistance, flexibility, and durability. It is ideal for use in highways, bridges, urban roads, airport runways, and industrial zones, particularly in hot climates or areas with heavy and continuous traffic loads. Its polymer modification improves its performance, making it resistant to deformation, rutting, and cracking.

Various Packing Method for Polymer Modified Bitumen PMB 70

Packing bitumen is an essential process to ensure its safe transportation, storage, and handling. The method of packing often depends on the type of bitumen, the transportation method, and the end-use. Here are the various methods used to pack bitumen:

Drum Packing

Bitumen is commonly packed in steel drums, which are robust and provide good protection during transportation.

Jumbo Packing

Bitumen is packed in high-density polyethylene (HDPE) bags and are lined with a plastic bag to prevent leakage.

Tank Container

These are large, insulated containers used for the international transport of bitumen.
