PG 76-22 Polymer Modified

Performance Grade 76-22 Polymer Modified Bitumen

Performance Grade (PG) bitumen PG 76-22 is a type of asphalt binder designed under the Superpave Performance Grading (PG) system. The numbers in the grade reflect the highest and lowest pavement temperatures at which the binder can effectively perform.

Is PG 76-22 Modified or Unmodified?

PG 76-22 is usually polymer-modified, which means it is enhanced with polymers to improve its elasticity, flexibility, and overall durability. This modification helps it better resist rutting at high temperatures and cracking at low temperatures, making it suitable for demanding environments.

Notes a - Pavement temperatures are estimated from air temperatures using an algorithm contained in the LTPP Bind program, may be provided by the specifying agency, or by following the procedures as outlined in M323 and R35. b - This requirement may be waived at the discretion of the specifying agency if the supplier warrants that the asphalt binder can be adequately pumped and mixed at temperatures that meet all applicable safety standards. c - For quality control of unmodified asphalt binder production, measurement of the viscosity of the original asphalt binder may be used to supplement dynamic shear measurements of G/sinδ at test temperatures where the asphalt is a Newtonian fluid. d - G/sin? = high temperature stiffness and G* sinδ = intermediate temperature stiffness. e - The mass change shall be less than 1.00 percent for either a positive (mass gain) or a negative (mass loss) change. f - If the creep stiffness is below 300 MPa, the direct tension test is not required. If the creep stiffness is between 300 and 600 MPa, the direct tension failure strain requirement can be used in lieu of the creep stiffness requirement. The m-value requirement must be satisfied in both cases.

Main Applications Of Performance Grade PG 76-22 Polymer Modified Bitumen

Highways and Major Roads: Used for high-traffic highways, expressways, and roads that face heavy traffic loads, where durability and resistance to rutting are critical.
Airport Runways and Taxiways: Applied in airports, particularly on runways, taxiways, and aprons, to handle the weight of aircraft and the extreme temperature fluctuations common in airport environments.
Bridges and Overpasses: Ideal for bridge decks and overpasses, where exposure to both heat and cold, as well as traffic stresses, can cause cracking and rutting if not properly managed.
Urban Roads and Industrial Areas: Suitable for urban environments and industrial areas that face heavy traffic, requiring high durability and resistance to deformation.
Regions with Extreme Climate Conditions: Effective in regions with extremely hot summers and cold winters, where temperature extremes can compromise the integrity of road surfaces.

PG 76-22 bitumen is a polymer-modified asphalt binder designed for use in areas with extreme temperature variations. Its ability to resist rutting at high temperatures and cracking at low temperatures makes it suitable for highways, airports, bridges, urban roads, and industrial areas. This binder is an ideal choice for demanding climates where roads need to endure both heavy traffic and intense weather conditions.
