Polymer Modified Bitumen PMB 40 - Technical Specifications

Key Characteristics of PMB 40

1. Polymer Modification: PMB 40 is modified with polymers such as styrene-butadiene-styrene (SBS), ethylene-vinyl-acetate (EVA), or other similar additives. This modification improves the bitumen’s resistance to deformation, cracking, and aging.

2. High Elastic Recovery: The polymer modification provides enhanced elasticity, allowing the binder to recover its shape after being deformed by traffic loads.

3. Enhanced Resistance: It has improved resistance to rutting at high temperatures, cracking at low temperatures, and fatigue under repeated traffic loads.

Main Applications Of Polymer Modified Bitumen PMB 40

PMB 40 is typically used in applications where high temperature stability, high load-bearing capacity, and flexibility are crucial:

1. Highways and Expressways: Used in high-traffic highways and expressways due to its high resistance to rutting and deformation under heavy and continuous traffic.

2. Urban Roads and Industrial Zones: Applied in urban areas and industrial zones where roads experience frequent heavy vehicle traffic and high temperature exposure.

3. Bridges and Elevated Roads: Suitable for bridge decks and overpasses due to its enhanced flexibility and resistance to thermal stresses, preventing cracking and rutting.

4. Airport Runways and Taxiways: Used in airport pavements where heavy aircraft loads and high temperatures demand superior resistance to rutting and deformation.

5. Heavy-Duty Pavements: Ideal for heavy-duty pavements such as those in container terminals, freight yards, and industrial facilities that see frequent loading and unloading activities.

PMB 40 is a polymer-modified bitumen with a penetration grade of 40. It is designed to offer high resistance to rutting, cracking, and deformation under heavy traffic loads and extreme temperature variations. Its polymer modification enhances its elasticity, durability, and flexibility, making it suitable for highways, bridges, airport runways, urban roads, and heavy-duty pavements in hot climates or high-stress conditions.

Various Packing Method for Polymer Modified Bitumen PMB 40

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.
