Investigating the Relationship of As-Constructed Asphalt Pavement Air Voids to Pavement Performance

The objective of this study was to determine the effect of in-place air voids (AV) on the performance of asphalt concrete (AC) pavements. The research focused on four primary distress types related to asphalt pavement performance: rutting, fatigue cracking, transverse cracking, and ride. The research team applied three analysis methods, described as Analysis Method 1, 2, and 3, to Long-Term Pavement Performance program (LTPP) data and then validated the results with data from other sources.
