Air voids are an important parameter in asphalt pavement construction. If air voids are too high or too low, pavement life can be reduced. The objective of NCHRP Project 20-50 (18) was to determine the effects of as-constructed air voids on performance using field data from the Long-Term Pavement Performance (LTPP) program.
