Simulating the Effects of Hot Mix Asphalt Aging for Performance Testing and Pavement Structural Design

This digest summarizes key findings from Part 1 of NCHRP Project 9-23, "Environmental Effects in Pavement Mix and Structural Design Systems." This project was conducted to (1) verify the work done under the SHRP Projects A-002, A-003, and A-005 in developing AASHTO Standard Practices R 28 and R 30 for simulating the real-world aging of asphalt binders and hot mix asphalt (HMA) mixes and (2) provide guidance on the significance of the limitations of the practices.
