This course offers the reader information on index-based performance tests that can be integrated into a PEMD (Performance Engineered Mixture Design) process to enhance the performance and extend the service life of asphalt pavements. It provides a general overview and context for the PEMD process, outlining how it fits into the larger picture.

The document presents a five-step procedure guideline for selecting and incorporating performance tests into an index-based PEMD process for asphalt mixture design and acceptance. It also identifies seven evaluation factors and their associated hierarchical levels, forming an approach to screen and assess the suitability of specific performance tests for use in an index-based PEMD process.

Key Topics Covered:

• Introduction
• Overview of the Performance Engineered Mixture Design (PEMD) Process
• Index-Based PEMD Practices
• Asphalt Mixture Performance
• Performance Test Selection Considerations
• Sample Evaluations of Performance Test Characteristics
• Summary
