What is Polymer Modified PG 76-10?
Polymer Modified PG 76-10 is a type of asphalt binder used in road construction and paving. It is a modified version of the base asphalt binder, PG 76-10, which stands for Performance Grade 76-10. The “PG” designation refers to the performance characteristics of the binder, such as its temperature susceptibility and resistance to rutting and cracking.
Polymer Modified PG 76-10 is made by adding polymers, such as styrene-butadiene-styrene (SBS) or styrene-butadiene rubber (SBR), to the base asphalt binder. This modification improves the binder’s properties, making it more durable and resistant to deformation under high temperatures and heavy traffic loads.
The addition of polymers enhances the elasticity and flexibility of the asphalt binder, allowing it to withstand thermal expansion and contraction, as well as resist cracking and rutting caused by repeated loading. This makes Polymer Modified PG 76-10 suitable for use in areas with extreme weather conditions or heavy traffic.
Advantage of Polymer Modified PG 76-10
1. Improved durability: The polymer modification enhances the binder’s resistance to deformation, cracking, and rutting, making it more durable and long-lasting. This results in reduced maintenance and repair costs over the lifespan of the road.
2. Enhanced temperature resistance: PG 76-10 has a high temperature susceptibility, meaning it can withstand a wide range of temperatures without becoming too soft or too brittle. This allows it to maintain its structural integrity in hot climates or during temperature fluctuations.
3. Increased flexibility: The addition of polymers improves the binder’s elasticity and flexibility, allowing it to better accommodate thermal expansion and contraction. This reduces the risk of cracking and damage due to temperature changes.
4. Improved resistance to aging: The polymer modification helps slow down the aging process of the asphalt binder, making it less prone to oxidation and deterioration over time. This prolongs the lifespan of the road and reduces the need for frequent repairs or resurfacing.
5. Better adhesion: PG 76-10 has excellent adhesion properties, allowing it to bond well with aggregates and form a strong and stable pavement structure. This results in improved pavement performance and reduces the likelihood of delamination or separation.
6. Versatility: PG 76-10 can be used in a variety of applications, including highways, urban roads, airports, and parking lots. It is suitable for both heavy traffic areas and low traffic volume roads.

Packing of Polymer Modified PG 76-10
G 76-10 asphalt binder is typically supplied in bulk quantities, such as tanker trucks or railcars, for large-scale road construction projects. It is also available in drums or totes for smaller applications or for ease of handling on job sites.
When packed in drums, PG 76-10 asphalt binder is usually stored and transported in standard 55-gallon steel drums. These drums are sealed to prevent contamination and maintain the quality of the binder during storage and transportation.
For larger quantities, PG 76-10 can be packed in totes, which are intermediate bulk containers (IBCs) that can hold several hundred gallons of the binder. Totes are often used when a larger volume of asphalt binder is required, but not enough to justify a tanker truck delivery.
Regardless of the packaging method, it is important to follow proper handling and storage procedures to ensure the quality and performance of the PG 76-10 asphalt binder. This includes protecting it from moisture, extreme temperatures, and contamination, as well as following any specific guidelines provided by the manufacturer.
