Performance Grade PG 64-22
Performance Grade PG 64-22 Bitumen Supplier
Performance Grade PG 64-22 Bitumen is an asphalt binder classified under the Superpave Performance Grade (PG) system, a classification method distinct from traditional penetration grading. Rather than measuring hardness at a single fixed temperature, the PG system defines binders according to the pavement temperature range they are engineered to withstand. The first number, 64, relates to the high-temperature performance classification, associated with resistance to deformation under warm conditions, while the second number, -22, relates to the low temperature performance classification, associated with resistance to thermal cracking. This combination indicates a binder intended for environments with a fairly wide temperature range, spanning warmer high temperatures and colder low temperature extremes. PG binder selection is intended to address specific pavement temperature and performance requirements, while actual pavement performance also depends on asphalt mixture design, traffic loading, aggregate properties, construction quality, and applicable project specifications. PG 64-22 specifications and technical properties are established through standardized Superpave testing methods, and buyers should confirm exact values through applicable test documentation. This grade may be relevant to road construction, highway construction and maintenance, and asphalt pavement production, with municipal roads, airport pavements, and heavy traffic applications considered where technically appropriate. Turkey Bitumen Supplies Performance Grade PG 64-22 Bitumen to international importers, asphalt plants, contractors, and procurement teams, supporting export orders around project specific requirements and technical documentation.
HY International has the capability to Export and Supply the Performance Grade Bitumen PG 64-22 in compliance with National and International standards.

Performance Grade PG 64-22 Bitumen Supplier
Performance Grade PG 64-22 Bitumen is an asphalt binder classified under the Superpave PG system, graded according to the high and low pavement temperatures it is designed to withstand, rather than by penetration hardness.
The "64" indicates the high temperature grade related to resistance against deformation, and the "-22" indicates the low-temperature grade related to resistance against thermal cracking, together defining a wide intended temperature range.
Penetration grading, such as 60/70, measures bitumen hardness at a fixed test temperature, while the PG system evaluates binder behavior across a range of expected in-service pavement temperatures, offering a climate-oriented classification.
PG 64-22 Bitumen may be used in road construction, highway construction and maintenance, and asphalt pavement production, with municipal roads and, where technically appropriate, airport pavements also considered.
Specifications are established through standardized Superpave testing addressing high and low temperature performance. Exact values should be confirmed through applicable test documentation and project design requirements.
Engineers select PG binders by matching the grade's high and low temperature ratings to the expected pavement temperature range at the project site, based on regional climate data and design specifications.
PG 64-22 may be suitable for highways and heavy traffic roads where the project's climate and temperature profile align with this grade, subject to engineering evaluation and applicable design specifications.
PG 64-22 may be considered for municipal roads and, where technically appropriate, airport and infrastructure projects, depending on the specific traffic loading and temperature performance requirements involved.
Buyers should confirm applicable PG test documentation, intended pavement temperature range, project specifications, packaging requirements, and shipping logistics before finalizing a purchase order.
Buyers can contact Turkey Bitumen with their required quantity, destination port, and project details to receive a quotation along with relevant technical information for Performance Grade PG 64-22 Bitumen.
