AASHTO PP 105-20 PDF Download

AASHTO PP 105-20 is a standard practice that provides guidance on achieving a balanced design of asphalt mixtures. The standard emphasizes the use of mixture volumetric properties and performance-based or related test results to develop a job mix formula for asphalt mixtures. It serves as a framework for selecting mix parameters and ensures that the design is based on a combination of performance requirements and volumetric properties.

The standard practice also allows for the use of preliminary mix parameters as a starting point for performance prediction analyses. This ensures that the design of asphalt mixtures takes into account both the desired performance characteristics and the volumetric properties required for durability and long-term performance.
