| description | Obtaining adequate density is a major requirement in the construction of hot mix
asphalt (HMA) pavements. Density is very much related to the air voids. As air voids increase,
the density decreases. This study determined the maximum in-place air void for impermeable
HMA pavements. A total of 497 core samples were obtained from 57 different ongoing HMA
construction projects immediately after rolling. Nine different mix types utilised in this study
were fine dense-graded 9.5 mm, 12.5 mm, 19.0 mm and 25.0 mm nominal maximum aggregate
size (NMAS) mixes, coarse dense-graded 9.5 mm, 12.5 mm and 19.0 mm NMAS mixes, and
Stone Matrix Asphalt (SMA) 9.5 mm and 25.0 mm NMAS mixes. Bulk specific gravity of each
core sample was determined using both American Association of State Highways and
Transportation Officials (AASHTO) T 166 and vacuum sealing methods, and permeability was
determined using American Society for Testing and Materials (ASTM) PS129-01. This study
found that in-place air void content was the most significant factor affecting permeability. The
in-place air voids for dense-graded HMA pavements should not exceed 7% |
