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 70-10 Bitumen

PG 70-10 Bitumen design allows for excellent resistance to rutting at elevated temperatures and cracking in colder weather, making it an ideal choice for various heavy-duty pavement applications. Various applications are

Highways and Major Roadways: Commonly used for paving high-traffic highways and major roadways in hot climates. Ensures stability and durability under heavy loads and elevated temperatures.
Airports and Runways: Suitable for airport runways and taxiways, where it can handle the weight and movement of aircraft without deforming.
Bridges and Overpasses: Applied in the construction of bridge decks and overpasses, providing resistance to deformation and cracking from thermal stresses.
Industrial Areas and Heavy Traffic Routes: Ideal for industrial roads and heavy-duty pavements, supporting high-load vehicles and ensuring long-lasting performance.
Rehabilitation Projects Used in asphalt overlays for the rehabilitation of existing pavements, enhancing their strength and durability.

Its high-performance characteristics make it suitable for heavy-duty pavements that need to withstand both high temperatures and significant traffic loads, ensuring durability and long-term service life.
