Investigating the Relationship of As-Constructed Asphalt Pavement Air Voids to Pavement Performance
Several controlled laboratory studies have shown that air voids (AV) can have a large
effect on the performance of asphalt pavements. AVs that are
either too high or too low can cause a reduction in pavement life.
The TRB National Cooperative Highway Research Program's
NCHRP Web-Only Document 299:
Investigating the Relationship of As-Constructed Asphalt Pavement Air Voids to Pavement Performance
determines the effect of in-place AVs on the performance of
asphalt concrete (AC) pavements.
The document also has supplemental appendices that are available by request to
Ed Harrigan. They include data sets for LTPP, Pavement ME Design Validation, MnROAD Validation, and NCAT Validation.
