Superpave performance grading (PG) is based on the idea that an HMA asphalt binder’s properties should be related to the conditions under which it is used. For asphalt binders, this involves expected climatic conditions as well as aging considerations.

The Performance Graded (PG) system is a method of measuring asphalt binder performance. It was originally developed during the Strategic Highway Research Program (SHRP) in the early 1990s. In 2005, California agreed to adopt the PG system for grading asphalts in the state.

Application of Performance Grade (PG) Bitumen. PG 52-28 is primarily used in paving for both new construction and pavement rehabilitation and in both dense-graded and open graded Hot Mix Asphalt (HMA). This product could also be used for sealing of …

2023年5月15日 · Discover the essential steps to accurately determine PG grade of asphalt for achieving optimal performance. This comprehensive guide provides valuable insights into the factors, considerations, and laboratory testing methods involved in asphalt PG grading.

The most advanced asphalt binder grading system is Performance Graded (PG) System, which is resulted from the $50 million Strategic Highway Research Program (SHRP) and has been adopted by all of the other 49 states in the U.S.

3 天之前 · The Performance Graded System. The performance graded (PG) system categorizes asphalt grades based on their performance under varying temperatures and conditions. It accounts for hot and cold climates and evaluates asphalt binders by testing their durability and flexibility. After exploring this brief guide to the different types of asphalt ...

There are mainly three grades of asphalt: penetration graded asphalt, viscosity graded asphalt, and performance graded asphalt. 1. Penetration Graded Asphalt: This type of asphalt is the most commonly used asphalt grade in the construction of roads and pavements.

McAsphalt’s performance-graded asphalt cement products meet or exceed the AASHTO M 320 and M 332 specification requirements and are engineered to address fundamental material properties that account for specific pavement distresses and failure mechanisms.

2024年1月31日 · Performance Grade (PG) bitumen grades like PG58 and PG52 are specifically designed to provide enhanced performance in environments where low temperatures can cause traditional asphalt to become brittle and crack.

Rather than a specific process or procedure, Superpave is a performance-based specification for asphalt binder and volumetric mixture design. The idea was to allow asphalt pavement designs that could handle the unique weather and traffic conditions of a given site in …
