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 70-16 Bitumen

PG 70-16 Bitumen ability to resist rutting in high temperatures and cracking in cooler conditions makes it suitable for heavy-duty pavements that require durability and performance. Various applications are

Highways and Major Roads: Commonly used for paving high-traffic highways and major roads where durability and resistance to deformation are critical. Ensures stability under heavy traffic loads and elevated temperatures.
Airport Runways and Taxiways: Suitable for airport pavements, including runways and taxiways, where it must withstand the weight of aircraft while maintaining performance.
Bridges and Overpasses: Used in the construction of bridge decks and flyovers, providing resistance to cracking from thermal stresses and heavy vehicle loads.
Industrial Areas and Heavy Traffic Routes: Ideal for industrial pavements, service roads, and areas with frequent heavy vehicle traffic. Ensures long-lasting performance and durability under demanding conditions.
Pavement Rehabilitation and Overlays: Commonly used in asphalt overlays for the rehabilitation of existing pavements, enhancing the performance and extending the life of older roads.
Parking Lots and Commercial Areas: Applied in commercial parking lots and shopping centers, providing a strong surface capable of handling regular vehicle traffic without deformation.
