TRR No. 1344 Pavement Design, Management, and Performance
Rutting is one of the most common forms of distress in hot mix asphalt (HMA) pavements, significantly affecting ride quality, safety, and structural performance. This study investigates the contributions of individual pavement structural layers—including the surface course, base course, and subgrade—to the overall rutting performance of HMA pavements. Through a combination of field observat…
