What is PG 76-10?
PG 76-10 is a grade of polymer-modified bitumen specifically formulated to perform better under hot weather and heavy traffic. “76” means that the binder maintains its properties at high service temperatures up to 76°C, and “-10” means it is flexible under low service temperatures down to -10°C. PG 76-10 is thus especially adapted for use in regions of severe heat and mild winter conditions where typical binders will rut or soften.
How Polymer Modification Enhances Performance?
PG 76-10 is enhanced with high-end polymers, such as Styrene-Butadiene-Styrene (SBS), which significantly increases the elasticity, strength, and resistance to deformation of the binder. The polymers create a network within the bitumen that increases its resistance to rutting, cracking, and premature aging—even under heavy traffic and harsh temperatures.
Unlike unpolymerized bitumen, PG 76-10 doesn’t lose its performance and consistency by softening or bleeding and is hence most appropriately used for pavements under cyclic loading and solar radiation.
Benefits of the Use of PG 76-10
Excellent Rut Resistance: Performs excellently under slow-moving or static loading such as intersections and roundabouts.
Thermal Stability: Performs excellently under hot surface temperatures prevalent in desert and tropical climates.
Long Pavement Life: Lower aging rate translates into less maintenance or overlay requirement.
Better Workability: Exhibits a highly favorable viscosity that is easy to mix, compact, and lay down without compromising performance.
Better Aggregate Bonding: Promotes better mix cohesion, less prone to stripping, cracking, and moisture damage.
Common Applications
PG 76-10 is designed for high-performance asphalt use, including:
Highways and major arterials subjected to extreme heat and load stress
Urban traffic and traffic circles subjected to rutting distress by stop-and-go conditions
Bus roads and BRT corridors with the need for long-term, enduring pavements
Airport taxiways and aprons, where surface performance is crucial
Industrial and port zones subjected to high axle loads and hot surface temperatures
Workability and Test Standards
PG 76-10 meets rut resistance, fatigue cracking, and low temperature performance under Superpave testing. It meets global standards like AASHTO M320, with high reliability for Middle East, Asian, and African projects.
Its best viscosity range supports easier handling, improved compaction, and mix design stability even with long-distance transportation or hot paving.
Sustainability and Cost Efficiency
Thanks to its longer service life and durability, PG 76-10 contributes to more sustainable road construction. By reducing the need for repeated maintenance cycles or resurfacing, it not only conserves operational costs but also saves the environment from reduced material consumption and emissions.
Its compatibility with recycled asphalt pavement (RAP) also supports sustainable building practices, which renders it an environmentally friendly choice for modern infrastructure.
